1+## Building instructions for Debian 13

2+

3+1. Install necessary software

4+ - `sudo apt install cmake golang gperf meson nasm ninja-build pkg-config rustup sdkmanager wget yasm`

5+ - `rustup default stable && rustup target add aarch64-linux-android armv7-linux-androideabi i686-linux-android x86_64-linux-android`

6+ - `sudo apt install google-android-platform-36-installer google-android-build-tools-36.0.0-installer google-android-ndk-r27c-installer openjdk-21-jdk-headless`

7+

8+2. Don't forget to include the submodules when you clone:

9+ - `git clone --recursive https://github.com/forkgram/TelegramAndroid.git`

10+

11+3. Build the native dependencies (BoringSSL, OpenH264, Opus, libvpx, dav1d, FFmpeg, tlottie and TDLib):

12+ - Go to the `TMessagesProj/jni` folder and execute the following (define the paths to your NDK and SDK):

13+

14+ ```

15+ export ANDROID_NDK_HOME=/usr/lib/android-sdk/ndk/27.2.12479018

16+ export ANDROID_SDK_ROOT=/usr/lib/android-sdk

17+ export ABIS="arm64-v8a armeabi-v7a"

18+ sudo sdkmanager "cmake;3.22.1" "ndk;27.2.12479018" --sdk_root /usr/lib/android-sdk

19+ ./prebuild/build_all.sh

20+ ```

21+

22+ The archives land in `TMessagesProj/jni/prebuild/lib/<abi>/`; drop `ABIS` to build all four.

23+

24+ Gradle runs the same steps automatically through `TMessagesProj/jni/prepare.py`.

25+

26+4. If you want to publish a modified version of Telegram:

27+ - You should get **your own API key** here: https://core.telegram.org/api/obtaining_api_id and edit a file called `gradle.properties` in the source root directory.

28+ The contents should look like this:

29+ ```

30+ APP_ID = 12345

31+ APP_HASH = aaaaaaaabbbbbbccccccfffffff001122

32+ ```

33+ - Do not use the name Telegram and the standard logo (white paper plane in a blue circle) for your app — or make sure your users understand that it is unofficial

34+ - Take good care of your users' data and privacy

35+ - **Please remember to publish your code too in order to comply with the licenses**

36+

37+The project can be built with Android Studio or from the command line with gradle:

38+

39+`./gradlew assembleAfatRelease`

40+

41+## Reproducible builds

42+

43+The repository ships a pinned Docker image and a build script that produce

44+byte-for-byte identical APKs across machines, given the same git revision and

45+signing key.

46+

47+Pinned in [docker/Dockerfile](docker/Dockerfile):

48+

49+- Ubuntu 22.04, JDK 17, UTC timezone, `C.UTF-8` locale

50+- Android command-line tools `11076708`

51+- SDK platform 36, Build Tools 36.0.0

52+- NDK `27.2.12479018` (native dependency scripts and gradle `externalNativeBuild`)

53+- CMake `3.22.1`

54+

55+### Building

56+

57+```

58+scripts/reproducible-build.sh

59+```

60+

61+`SOURCE_DATE_EPOCH` is taken from `git log -1 --format=%ct HEAD`, then exported

62+into the container. The script applies [reproducible.gradle](reproducible.gradle)

63+as an init script, which forces `preserveFileTimestamps = false` and

64+`reproducibleFileOrder = true` on every archive task (AGP 8 already does this

65+for APKs and AABs; the init script covers custom Zip/Jar tasks).

66+

67+To build a non-default target:

68+

69+```

70+scripts/reproducible-build.sh :TMessagesProj_App:bundleBundleAfatRelease

71+```

72+

73+### Verifying a published APK

74+

75+```

76+scripts/verify-apk.sh path/to/published.apk \

77+ TMessagesProj_App/build/outputs/apk/afat/release/app.apk

78+```

79+

80+The script delegates to [apkdiff.py](apkdiff.py) which ignores the v1 signature

81+block (`META-INF/MANIFEST.MF`, `META-INF/CERT.RSA`, `META-INF/CERT.SF`) since

82+those depend on the signing key, not on the source.

83+

84+### Known caveats

85+

86+- **Build host OS leaks into the APK.** `Utilities.parseInt` branches on

87+ `BuildConfig.BUILD_HOST_IS_WINDOWS`, which is set at build time. The

88+ reproducible image is Linux, so the canonical value is always `false`.

89+ Builds run directly on Windows will diverge.

90+- **Signing key.** Two builds signed with different keys will differ in the

91+ signature blocks. Use `scripts/verify-apk.sh` to compare ignoring those

92+ entries, or sign the rebuilt APK with the same key before comparing.

93+- **NDK / AGP upgrades.** Bumping `ndkVersion`, `buildToolsVersion`, or the

94+ AGP/Kotlin plugin versions invalidates the reproducibility baseline. Update

95+ the Docker image in the same commit and rebuild the reference APK.

1+ GNU GENERAL PUBLIC LICENSE

2+ Version 2, June 1991

3+

4+ Copyright (C) 1989, 1991 Free Software Foundation, Inc.,

5+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA

6+ Everyone is permitted to copy and distribute verbatim copies

7+ of this license document, but changing it is not allowed.

8+

9+ Preamble

10+

11+ The licenses for most software are designed to take away your

12+freedom to share and change it. By contrast, the GNU General Public

13+License is intended to guarantee your freedom to share and change free

14+software--to make sure the software is free for all its users. This

15+General Public License applies to most of the Free Software

16+Foundation's software and to any other program whose authors commit to

17+using it. (Some other Free Software Foundation software is covered by

18+the GNU Lesser General Public License instead.) You can apply it to

19+your programs, too.

20+

21+ When we speak of free software, we are referring to freedom, not

22+price. Our General Public Licenses are designed to make sure that you

23+have the freedom to distribute copies of free software (and charge for

24+this service if you wish), that you receive source code or can get it

25+if you want it, that you can change the software or use pieces of it

26+in new free programs; and that you know you can do these things.

27+

28+ To protect your rights, we need to make restrictions that forbid

29+anyone to deny you these rights or to ask you to surrender the rights.

30+These restrictions translate to certain responsibilities for you if you

31+distribute copies of the software, or if you modify it.

32+

33+ For example, if you distribute copies of such a program, whether

34+gratis or for a fee, you must give the recipients all the rights that

35+you have. You must make sure that they, too, receive or can get the

36+source code. And you must show them these terms so they know their

37+rights.

38+

39+ We protect your rights with two steps: (1) copyright the software, and

40+(2) offer you this license which gives you legal permission to copy,

41+distribute and/or modify the software.

42+

43+ Also, for each author's protection and ours, we want to make certain

44+that everyone understands that there is no warranty for this free

45+software. If the software is modified by someone else and passed on, we

46+want its recipients to know that what they have is not the original, so

47+that any problems introduced by others will not reflect on the original

48+authors' reputations.

49+

50+ Finally, any free program is threatened constantly by software

51+patents. We wish to avoid the danger that redistributors of a free

52+program will individually obtain patent licenses, in effect making the

53+program proprietary. To prevent this, we have made it clear that any

54+patent must be licensed for everyone's free use or not licensed at all.

55+

56+ The precise terms and conditions for copying, distribution and

57+modification follow.

58+

59+ GNU GENERAL PUBLIC LICENSE

60+ TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION

61+

62+ 0. This License applies to any program or other work which contains

63+a notice placed by the copyright holder saying it may be distributed

64+under the terms of this General Public License. The "Program", below,

65+refers to any such program or work, and a "work based on the Program"

66+means either the Program or any derivative work under copyright law:

67+that is to say, a work containing the Program or a portion of it,

68+either verbatim or with modifications and/or translated into another

69+language. (Hereinafter, translation is included without limitation in

70+the term "modification".) Each licensee is addressed as "you".

71+

72+Activities other than copying, distribution and modification are not

73+covered by this License; they are outside its scope. The act of

74+running the Program is not restricted, and the output from the Program

75+is covered only if its contents constitute a work based on the

76+Program (independent of having been made by running the Program).

77+Whether that is true depends on what the Program does.

78+

79+ 1. You may copy and distribute verbatim copies of the Program's

80+source code as you receive it, in any medium, provided that you

81+conspicuously and appropriately publish on each copy an appropriate

82+copyright notice and disclaimer of warranty; keep intact all the

83+notices that refer to this License and to the absence of any warranty;

84+and give any other recipients of the Program a copy of this License

85+along with the Program.

86+

87+You may charge a fee for the physical act of transferring a copy, and

88+you may at your option offer warranty protection in exchange for a fee.

89+

90+ 2. You may modify your copy or copies of the Program or any portion

91+of it, thus forming a work based on the Program, and copy and

92+distribute such modifications or work under the terms of Section 1

93+above, provided that you also meet all of these conditions:

94+

95+ a) You must cause the modified files to carry prominent notices

96+ stating that you changed the files and the date of any change.

97+

98+ b) You must cause any work that you distribute or publish, that in

99+ whole or in part contains or is derived from the Program or any

100+ part thereof, to be licensed as a whole at no charge to all third

101+ parties under the terms of this License.

102+

103+ c) If the modified program normally reads commands interactively

104+ when run, you must cause it, when started running for such

105+ interactive use in the most ordinary way, to print or display an

106+ announcement including an appropriate copyright notice and a

107+ notice that there is no warranty (or else, saying that you provide

108+ a warranty) and that users may redistribute the program under

109+ these conditions, and telling the user how to view a copy of this

110+ License. (Exception: if the Program itself is interactive but

111+ does not normally print such an announcement, your work based on

112+ the Program is not required to print an announcement.)

113+

114+These requirements apply to the modified work as a whole. If

115+identifiable sections of that work are not derived from the Program,

116+and can be reasonably considered independent and separate works in

117+themselves, then this License, and its terms, do not apply to those

118+sections when you distribute them as separate works. But when you

119+distribute the same sections as part of a whole which is a work based

120+on the Program, the distribution of the whole must be on the terms of

121+this License, whose permissions for other licensees extend to the

122+entire whole, and thus to each and every part regardless of who wrote it.

123+

124+Thus, it is not the intent of this section to claim rights or contest

125+your rights to work written entirely by you; rather, the intent is to

126+exercise the right to control the distribution of derivative or

127+collective works based on the Program.

128+

129+In addition, mere aggregation of another work not based on the Program

130+with the Program (or with a work based on the Program) on a volume of

131+a storage or distribution medium does not bring the other work under

132+the scope of this License.

133+

134+ 3. You may copy and distribute the Program (or a work based on it,

135+under Section 2) in object code or executable form under the terms of

136+Sections 1 and 2 above provided that you also do one of the following:

137+

138+ a) Accompany it with the complete corresponding machine-readable

139+ source code, which must be distributed under the terms of Sections

140+ 1 and 2 above on a medium customarily used for software interchange; or,

141+

142+ b) Accompany it with a written offer, valid for at least three

143+ years, to give any third party, for a charge no more than your

144+ cost of physically performing source distribution, a complete

145+ machine-readable copy of the corresponding source code, to be

146+ distributed under the terms of Sections 1 and 2 above on a medium

147+ customarily used for software interchange; or,

148+

149+ c) Accompany it with the information you received as to the offer

150+ to distribute corresponding source code. (This alternative is

151+ allowed only for noncommercial distribution and only if you

152+ received the program in object code or executable form with such

153+ an offer, in accord with Subsection b above.)

154+

155+The source code for a work means the preferred form of the work for

156+making modifications to it. For an executable work, complete source

157+code means all the source code for all modules it contains, plus any

158+associated interface definition files, plus the scripts used to

159+control compilation and installation of the executable. However, as a

160+special exception, the source code distributed need not include

161+anything that is normally distributed (in either source or binary

162+form) with the major components (compiler, kernel, and so on) of the

163+operating system on which the executable runs, unless that component

164+itself accompanies the executable.

165+

166+If distribution of executable or object code is made by offering

167+access to copy from a designated place, then offering equivalent

168+access to copy the source code from the same place counts as

169+distribution of the source code, even though third parties are not

170+compelled to copy the source along with the object code.

171+

172+ 4. You may not copy, modify, sublicense, or distribute the Program

173+except as expressly provided under this License. Any attempt

174+otherwise to copy, modify, sublicense or distribute the Program is

175+void, and will automatically terminate your rights under this License.

176+However, parties who have received copies, or rights, from you under

177+this License will not have their licenses terminated so long as such

178+parties remain in full compliance.

179+

180+ 5. You are not required to accept this License, since you have not

181+signed it. However, nothing else grants you permission to modify or

182+distribute the Program or its derivative works. These actions are

183+prohibited by law if you do not accept this License. Therefore, by

184+modifying or distributing the Program (or any work based on the

185+Program), you indicate your acceptance of this License to do so, and

186+all its terms and conditions for copying, distributing or modifying

187+the Program or works based on it.

188+

189+ 6. Each time you redistribute the Program (or any work based on the

190+Program), the recipient automatically receives a license from the

191+original licensor to copy, distribute or modify the Program subject to

192+these terms and conditions. You may not impose any further

193+restrictions on the recipients' exercise of the rights granted herein.

194+You are not responsible for enforcing compliance by third parties to

195+this License.

196+

197+ 7. If, as a consequence of a court judgment or allegation of patent

198+infringement or for any other reason (not limited to patent issues),

199+conditions are imposed on you (whether by court order, agreement or

200+otherwise) that contradict the conditions of this License, they do not

201+excuse you from the conditions of this License. If you cannot

202+distribute so as to satisfy simultaneously your obligations under this

203+License and any other pertinent obligations, then as a consequence you

204+may not distribute the Program at all. For example, if a patent

205+license would not permit royalty-free redistribution of the Program by

206+all those who receive copies directly or indirectly through you, then

207+the only way you could satisfy both it and this License would be to

208+refrain entirely from distribution of the Program.

209+

210+If any portion of this section is held invalid or unenforceable under

211+any particular circumstance, the balance of the section is intended to

212+apply and the section as a whole is intended to apply in other

213+circumstances.

214+

215+It is not the purpose of this section to induce you to infringe any

216+patents or other property right claims or to contest validity of any

217+such claims; this section has the sole purpose of protecting the

218+integrity of the free software distribution system, which is

219+implemented by public license practices. Many people have made

220+generous contributions to the wide range of software distributed

221+through that system in reliance on consistent application of that

222+system; it is up to the author/donor to decide if he or she is willing

223+to distribute software through any other system and a licensee cannot

224+impose that choice.

225+

226+This section is intended to make thoroughly clear what is believed to

227+be a consequence of the rest of this License.

228+

229+ 8. If the distribution and/or use of the Program is restricted in

230+certain countries either by patents or by copyrighted interfaces, the

231+original copyright holder who places the Program under this License

232+may add an explicit geographical distribution limitation excluding

233+those countries, so that distribution is permitted only in or among

234+countries not thus excluded. In such case, this License incorporates

235+the limitation as if written in the body of this License.

236+

237+ 9. The Free Software Foundation may publish revised and/or new versions

238+of the General Public License from time to time. Such new versions will

239+be similar in spirit to the present version, but may differ in detail to

240+address new problems or concerns.

241+

242+Each version is given a distinguishing version number. If the Program

243+specifies a version number of this License which applies to it and "any

244+later version", you have the option of following the terms and conditions

245+either of that version or of any later version published by the Free

246+Software Foundation. If the Program does not specify a version number of

247+this License, you may choose any version ever published by the Free Software

248+Foundation.

249+

250+ 10. If you wish to incorporate parts of the Program into other free

251+programs whose distribution conditions are different, write to the author

252+to ask for permission. For software which is copyrighted by the Free

253+Software Foundation, write to the Free Software Foundation; we sometimes

254+make exceptions for this. Our decision will be guided by the two goals

255+of preserving the free status of all derivatives of our free software and

256+of promoting the sharing and reuse of software generally.

257+

258+ NO WARRANTY

259+

260+ 11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY

261+FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN

262+OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

263+PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED

264+OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF

265+MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE. THE ENTIRE RISK AS

266+TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU. SHOULD THE

267+PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,

268+REPAIR OR CORRECTION.

269+

270+ 12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING

271+WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR

272+REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,

273+INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING

274+OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED

275+TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY

276+YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER

277+PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE

278+POSSIBILITY OF SUCH DAMAGES.

279+

280+ END OF TERMS AND CONDITIONS

281+

282+ How to Apply These Terms to Your New Programs

283+

284+ If you develop a new program, and you want it to be of the greatest

285+possible use to the public, the best way to achieve this is to make it

286+free software which everyone can redistribute and change under these terms.

287+

288+ To do so, attach the following notices to the program. It is safest

289+to attach them to the start of each source file to most effectively

290+convey the exclusion of warranty; and each file should have at least

291+the "copyright" line and a pointer to where the full notice is found.

292+

293+ <one line to give the program's name and a brief idea of what it does.>

294+ Copyright (C) <year> <name of author>

295+

296+ This program is free software; you can redistribute it and/or modify

297+ it under the terms of the GNU General Public License as published by

298+ the Free Software Foundation; either version 2 of the License, or

299+ (at your option) any later version.

300+

301+ This program is distributed in the hope that it will be useful,

302+ but WITHOUT ANY WARRANTY; without even the implied warranty of

303+ MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the

304+ GNU General Public License for more details.

305+

306+ You should have received a copy of the GNU General Public License along

307+ with this program; if not, write to the Free Software Foundation, Inc.,

308+ 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.

309+

310+Also add information on how to contact you by electronic and paper mail.

311+

312+If the program is interactive, make it output a short notice like this

313+when it starts in an interactive mode:

314+

315+ Gnomovision version 69, Copyright (C) year name of author

316+ Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.

317+ This is free software, and you are welcome to redistribute it

318+ under certain conditions; type `show c' for details.

319+

320+The hypothetical commands `show w' and `show c' should show the appropriate

321+parts of the General Public License. Of course, the commands you use may

322+be called something other than `show w' and `show c'; they could even be

323+mouse-clicks or menu items--whatever suits your program.

324+

325+You should also get your employer (if you work as a programmer) or your

326+school, if any, to sign a "copyright disclaimer" for the program, if

327+necessary. Here is a sample; alter the names:

328+

329+ Yoyodyne, Inc., hereby disclaims all copyright interest in the program

330+ `Gnomovision' (which makes passes at compilers) written by James Hacker.

331+

332+ <signature of Ty Coon>, 1 April 1989

333+ Ty Coon, President of Vice

334+

335+This General Public License does not permit incorporating your program into

336+proprietary programs. If your program is a subroutine library, you may

337+consider it more useful to permit linking proprietary applications with the

338+library. If this is what you want to do, use the GNU Lesser General

339+Public License instead of this License.

1+# Notifications

2+

3+Since [Android 8.0 Oreo, Google doesn't allow apps to run in the background anymore](https://developer.android.com/about/versions/oreo/background#services), requiring all apps which were previously keeping background connection to exclusively use its Firebase push messaging service.

4+

5+As one can't use Google's push messaging in a FOSS app, Telegram-FOSS has to show you a notification to keep the background service running. Otherwise, you wouldn't be notified about new messages.

6+

7+Sadly, if the app would set the notification to lower priority (to hide it a bit in the lower part of the notification screen), you would immediately get a system notification about Telegram "using battery", which is confusing and is the reason for this not being the default. Despite Google's misleading warnings, there is no difference in battery usage between v4.6 in "true background" and v4.9+ with notification.

8+

9+## Make it better

10+

11+You may still lower the priority of the notification channel or even hide it altogether manually (make a long tap on the notification). You will then receive the misleading system notification, which [may be disabled as well with another long tap](https://9to5google.com/2017/10/26/how-to-disable-android-oreo-using-battery-notification-android-basics/).

1−# MultiGram

2−

3−MultiGram is Forkgram (https://github.com/forkgram/TelegramAndroid) plus a small stack of MultiGram changes.

4−

5−| Branch | What it holds |

6−|---|---|

7−| `forkgram` | Snapshots of Forkgram's `dev` branch, one commit per Forkgram release (the `.github` folder is left out). |

8−| `multigram` | The app: the latest `forkgram` snapshot plus the MultiGram commits on top. Build this branch. |

9−| `main` | This README, the automation that keeps `multigram` in step with Forkgram, and helper scripts. |

10−

11−The sync also uses `multigram-next` (the next `multigram`, while it is being checked) and tags

12−the `multigram` it replaces as `multigram-before-<version>`.

13−

14−[PATCH.md](https://github.com/iko-soy/Multigram/blob/docs/PATCH.md) on the `docs` branch says what

15−to do after a Telegram update when the sync needs a hand, and lists every MultiGram change with

16−the exact code, so the stack can be re-applied by hand.

17−

18−## Build

19−

20−**Actions > Build MultiGram > Run workflow**, ref `multigram`. It compiles the Java and Kotlin

21−code (a few minutes). Tick **APK** to also build a release APK; it compiles the native code

22−too, so it takes much longer, and the APK is attached to the run as `multigram-apk`.

23−

24−## Releases

25−

26−**Actions > Release MultiGram > Run workflow** builds the release APK of `multigram` and publishes

27−it on the Releases page (about 80 minutes; tick **dry_run** to see only the version and notes).

28−Versions follow Forkgram's scheme: `12.10.6.1` is the first MultiGram release on Forkgram 12.10.6,

29−`12.10.6.2` the second, and after a Forkgram update the count starts again at 1 (at most 9 per

30−Forkgram version). The tag is the version. It needs the API id and hash secrets below. Without the

31−signing secrets the APK is signed with Forkgram's public test key and published as a pre-release

32−that says so. Details: section 10.6 of

33−[PATCH.md](https://github.com/iko-soy/Multigram/blob/docs/PATCH.md).

34−

35−## Secrets

36−

37−Set these in **Settings > Secrets and variables > Actions**:

38−

39−- `MULTIGRAM_APP_ID` and `MULTIGRAM_APP_HASH`: your own API id and hash from

40− https://my.telegram.org (API development tools). Without them the APK cannot log in.

41−- Signing (optional): `MULTIGRAM_KEYSTORE_BASE64` (your release keystore, `base64 -w0 release.keystore`),

42− `MULTIGRAM_KEYSTORE_PASSWORD`, `MULTIGRAM_KEY_ALIAS` and `MULTIGRAM_KEY_PASSWORD` (if it differs

43− from the store password). Without them the APK is signed with Forkgram's public test key

44− (`TMessagesProj/config/test.keystore`), which is fine for testing but lets anyone sign an

45− "update" for it. Keep the same key for every build you give out, or phones can't update. The

46− rebrand toolkit can make a key for you (see "Signing and updates" in `multigram/rebrand/README.md`).

47−

48−## How the sync works

49−

50−The **Sync with Forkgram** workflow runs every 6 hours (and by hand):

51−

52−1. If Forkgram's `dev` has a new tip (Forkgram rebases `dev` onto every Telegram release, so each

53− new tip is a release candidate), it adds a snapshot commit to `forkgram`: that tree without

54− `.github`, with `Forkgram-Commit`, `Forkgram-Version` and `Telegram-Base` lines in the message.

55−2. It replays the MultiGram commits (`forkgram..multigram`) onto the snapshot as `multigram-next`

56− (`git rebase --onto`).

57−3. It compiles `multigram-next` with the Build MultiGram workflow.

58−4. If that passes, it tags the old `multigram` as `multigram-before-<version>`, moves `multigram`

59− to `multigram-next`, deletes `multigram-next` and closes the sync issue.

60−5. On a conflict or a failed compile it opens an issue labelled `forkgram-sync` (or comments on the

61− open one) with the details; `multigram` stays as it was.

62−

63−It never replaces a `multigram-next` that has commits it did not make (your fix, say): it then

64−changes nothing, not even `forkgram`, and says so on the issue until you run **use_next** or

65−delete `multigram-next`. It records the `multigram-next` it built last in the ref

66−`refs/multigram-sync/next`. Keep `multigram` linear (rebase, do not merge): the replay flattens

67−merges, so a merge commit with changes of its own stops the sync.

68−

69−Run it by hand with **force** to rebuild `multigram-next` without a new release (to test the

70−pipeline, or to retry), or with **use_next** to compile and promote a `multigram-next` you fixed

71−yourself. **use_next** checks that `multigram-next` still has every commit on `multigram` (a

72−commit pushed to `multigram` after you started the fix would otherwise be lost); tick

73−**allow_drop** as well if it leaves some out on purpose.

74−

75−The work is done by `scripts/sync-forkgram.sh` (see `--help`). It also runs locally without

76−pushing anything: from a checkout of `main`, `bash scripts/sync-forkgram.sh --remote origin`

77−leaves the results in your local `forkgram` and `multigram-next` branches.

78−`bash scripts/selftest-sync.sh` tests it against fake repositories.

79−

80−rerere (git's memory of conflict fixes) only knows the fixes recorded in the clone it runs in.

81−It helps when you redo a rebase or run the script in your own clone; the scheduled sync starts

82−from a fresh clone every time, so it reports a conflict again until `multigram` carries the fix.

83−

84−## When the sync issue opens

85−

86−The issue has the exact commands; in short:

87−

88−**Conflict.** Replay the stack yourself, fix the files, push the result to `multigram-next`:

89−

90−```sh

91−git fetch origin

92−git switch -C multigram-next origin/multigram

93−git config rerere.enabled true # reuses your fixes if you redo this rebase here

94−git rebase origin/forkgram

95−# fix the files git names, then: git add <files> && git rebase --continue (repeat)

96−git push --force origin multigram-next

97−```

98−

99−**Compile failure.** Fix the build on top of `multigram-next` and fold the fix into the commit it

100−belongs to:

101−

102−```sh

103−git fetch origin

104−git switch -C multigram-next origin/multigram-next

105−# edit, then, once per MultiGram commit your fix touches (name only that commit's files):

106−git commit --fixup=<the MultiGram commit it belongs to> -- <its files>

107−GIT_SEQUENCE_EDITOR=: git rebase -i --autosquash origin/forkgram

108−git push --force origin multigram-next

109−```

110−

111−Then **Actions > Sync with Forkgram > Run workflow** with **use_next** ticked: it compiles

112−`multigram-next` and, if that passes, moves `multigram` to it and closes the issue. If the

113−compile failed because of a runner or network hiccup, **Re-run failed jobs** on the run page

114−is enough. Until then the sync leaves your `multigram-next` alone; if you give up on it, delete

115−it (`git push origin --delete multigram-next`) and the next sync starts over from `multigram`.

116−

117−## Patches

118−

119−`bash scripts/export-patches.sh --base origin/forkgram --head origin/multigram` writes the stack

120−as numbered patches to `multigram-patches/`, with `APPLY.txt` saying how to apply them onto a

121−plain Forkgram checkout (`git am -3`).

122−

123−## What is on the multigram branch

124−

125−- `multigram/rebrand/`: the rebrand toolkit that gives a build its own name, applicationId,

126− launcher icon and signing key (instructions in its `README.md`).

127−- `multigram/hide-search-bar/`: the "Hide chat list search" option in Fork Client Settings >

128− Chat list view (off by default), which removes the search bar and search icon from the chat list.

129−- `multigram/`: the other MultiGram tools and notes, such as the per-install random style and

130− its palette check; the app code is in

131− `TMessagesProj/src/main/java/org/telegram/messenger/multigram/`.

132−

133−## Repository settings

134−

135−- `main` must be the default branch: scheduled workflows only run from it.

136−- The workflows ask for the token permissions they need, so the default workflow permissions

137− can stay read-only.

138−- Issues must be enabled: the sync reports on an issue labelled `forkgram-sync`.

139−- If you protect `forkgram`, `multigram`, `multigram-next` or `multigram-before-*` tags with

140− branch protection or rulesets, let GitHub Actions push and force-push them.

3+All integers are little endian. No global compression. Images and index maps are 64×64, row-major. Emoji records precede internal mask records; keys are strictly increasing within each section. The public loader returns a complete Bitmap; none of these storage details are public API.

28+| 12 | u16 | Second parent record index, or 65535 |

29+| 14 | u16 | Palette size 1…256; zero for whole images |

30+| 16 | u8 | Codec |

31+| 17 | u8 | Prediction |

32+| 18 | u8 | Low 7 bits: palette channels 0, 1, 3 or 4; bit 7: compressed palette |

33+| 19 | u8 | Flags, described below |

34+

35+Parent values are indices in the entire record table, not emoji keys or mask IDs. A parent must be an independent indexed record: codec 0 or 1, prediction 0, no parents. Dependency chains are forbidden. A record may reference the same root for both halves, with independent transforms and remapping tables. Internal mask records cannot themselves reference a mask.

36+

37+Flags:

38+

39+- Bit 0: palette components packed into seven bits.

40+- Bits 1…3: transform of the first parent map.

41+- Bits 4…6: transform of the second parent map.

42+- Bit 7: selected with the visual quality gate; informational to the runtime.

43+

44+Whole-image records have no palette, no parents and prediction 0. Their only permitted flag is bit 7. Unused transform fields written by the builder are zero.

45+

46+## Palettes

47+

48+Indexed payloads start with their palette, optionally compressed as described below. Channels 0 means implicit opaque gray: `palette[i] = (i,i,i,255)`, palette size must be 256, no stored bytes. Channels 1 stores opaque grayscale. Channels 3 stores RGB with alpha 255. Channels 4 stores RGBA, unpremultiplied.

49+

50+If flag bit 0 is clear, components are ordinary bytes. Otherwise each component `v` is representable as `v = (q << 1) | (q >> 6)` for a seven-bit `q`. Store q as a continuous LSB-first bitstream; pad unused final bits with zero. Stored palette length is `ceil(colors * channels * 7 / 8)`. This packing itself is reversible, without extra posterization.

51+

52+If bit 7 of the channel byte is set, the stored palette prefix is `u16(compressedLength)` followed by a raw DEFLATE stream of exactly compressedLength bytes. Its output is the ordinary stored palette representation described above, including seven-bit packing when flag bit 0 is set. The expected output length is therefore either `colors * channels` or `ceil(colors * channels * 7 / 8)`. No dictionary, zlib header or checksum is used. Channel count zero cannot have a compressed palette.

53+

54+This palette stream is independent of the index/residual stream. It is inflated only when the palette is actually used for color expansion; loading a parent index map skips its palette without inflating it. The same Inflater and scratch arrays are reused.

55+

56+## Codecs

57+

58+| Codec | Payload after palette |

59+|---:|---|

60+| 0 | Raw DEFLATE, without zlib header/checksum; decoded bytes are concatenated LUTs, then 4096 residual/index bytes |

61+| 1 | Concatenated uncompressed LUTs, then a VP8L chunk payload; decode to an opaque grayscale index/residual image |

62+| 2 | Whole RGBA VP8L chunk payload; no palette or prediction |

63+| 3 | Complete standard PNG or WebP file; no palette or prediction |

64+| 4 | No stream: payload contains only the palette; prediction must be 4 |

65+

66+For codecs 1 and 2, the 20-byte RIFF/WEBP/VP8L wrapper and final RIFF padding byte are omitted. Before BitmapFactory decoding, rebuild `RIFF`, `u32(12 + payloadLength + padding)`, `WEBPVP8L`, `u32(payloadLength)`, payload, and a zero padding byte if payloadLength is odd. Encoded stream bytes are otherwise unchanged. For codec 1 the LUTs are not included in payloadLength here.

67+

68+Codec 3 stores the entire image file unchanged, including its container. The current pack uses it for one original PNG and 16 lossy WebP images. Codec 4 requires the same palette size as its parent; its palette may contain different colors.

69+

70+## Prediction and geometry

71+

72+| Prediction | Reconstruction |

73+|---:|---|

74+| 0 | No LUTs or parents; decoded byte is the palette index |

75+| 1 | `index = residual XOR lut[parentIndex]` |

76+| 2 | `index = (residual + lut[parentIndex]) & 255` |

77+| 3 | Same addition, first LUT/parent for destination x < 32, second LUT/parent for x ≥ 32 |

78+| 4 | Copy indices from the transformed parent; no residual stream and no LUT |

79+| 5 | Addition as in prediction 3; vertical split at the stored column |

80+| 6 | Addition as in prediction 3; horizontal split at the stored row |

81+

82+Predictions 5 and 6 store one cut byte, in the range 1…63, immediately after the palette prefix and before the codec payload. This byte is outside both compressed streams. Prediction 3 stores no cut byte and keeps its fixed split at column 32. Prediction 6 samples parent A above the cut and parent B below it; prediction 5 samples A to the left and B to the right.

83+

84+Each LUT contains exactly one byte per palette entry of its parent. For two halves, store the first LUT followed by the second. All split positions are in destination coordinates. There is no scaling, blending or positional offset.

85+

86+A three-bit transform maps each destination pixel to the source position in the parent map:

87+

88+```text

89+x = destinationIndex & 63

90+y = destinationIndex >> 6

91+if transform & 1: x = 63 - x

92+if transform & 2: y = 63 - y

93+if transform & 4: swap(x, y)

94+sourceIndex = y * 64 + x

95+```

96+

97+Thus transform 1 is a horizontal reflection and transform 2 is a vertical reflection. Transform 4 transposes the square. The eight combinations cover the symmetries of the square. They affect parent sampling only, not the current residual stream or palette. No transformed Bitmap needs to be allocated.

98+

99+The restored index must be smaller than the current palette size. Final palette expansion produces straight ARGB components.

100+

101+## Complete emoji reconstruction

102+

103+`getEmoji(x, y)` privately looks up the emoji key and decodes its color record. If an internal mask is present, the loader decodes that grayscale record and combines alpha before creating the final Bitmap:

104+

105+```text

106+finalAlpha = (colorAlpha * maskGray + 127) / 255 // integer division

107+```

108+

109+RGB components stay straight until Bitmap creation. Android Bitmap creation performs its normal premultiplication. For full images used with a mask, decoding requests unpremultiplied pixels first. A native full image with no separate mask may be returned directly as a premultiplied Bitmap.

110+

111+The caller receives one complete ARGB_8888 Bitmap and owns it. The loader does not cache the returned Bitmap. Internal mask IDs and mask accessors are not exposed. The root-map cache is independent of Bitmap ownership and bounded to eight 4096-byte maps. All decode operations on one loader are synchronized.

112+

113+## Validation and integrity

114+

115+The loader checks the header, record bounds, references, independent roots, palette indices, dimensions and stream lengths. It does not decompress all images at startup. The pack has no per-record checksum and is intended to be shipped as a trusted application asset. The independent verifier and supplied SHA-256 hashes establish build integrity.

116+

117+Version 3 adds variable horizontal/vertical splits (predictions 5/6) and optional palette compression (bit 7 of the channel byte). Header and record sizes remain unchanged. The supplied Java reader supports both versions 2 and 3. The old v2 reader cannot read v3; replace the pack and loader together. The public getEmoji contract continues to return a complete Bitmap.

20+# build_opus/ is used as temporary workspace and is removed after a successful

21+# build. Sources are never copied.

22+#

23+# Why an explicit source list instead of opus's own CMake:

24+# for the FIXED_POINT ARM path, opus's CMake defines

25+# OPUS_ARM_MAY_HAVE_NEON / OPUS_ARM_PRESUME_NEON, which make the code reference

26+# celt_pitch_xcorr_neon -- a symbol provided only by celt/arm/celt_pitch_xcorr_arm.s.

27+# Instead, this build enables only the NEON intrinsic sources/macros, avoiding

28+# the asm-only symbol while still retaining NEON acceleration.

29+#

30+# Optional environment overrides:

31+# OPUS_SOURCE_DIR=/path/to/opus

32+# ANDROID_NDK_HOME=/path/to/ndk

33+# ANDROID_SDK_ROOT=/path/to/sdk
