Building

NOTE: Building on Windows is, unfortunately, not supported. Consider using a Linux VM or dual booting.

Important:

You need the Android NDK, Go(Golang) and Ninja to build the apk.
Don't forget to include the submodules when you clone:
- git clone --recursive https://github.com/Telegram-FOSS-Team/Telegram-FOSS.git

Build native FFmpeg and BoringSSL dependencies:

Go to the TMessagesProj/jni folder and execute the following (define the paths to your NDK and Ninja):

export NDK=[PATH_TO_NDK]
export NINJA_PATH=[PATH_TO_NINJA]
./build_libvpx_clang.sh
./build_ffmpeg_clang.sh
./patch_ffmpeg.sh
./patch_boringssl.sh
./build_boringssl.sh

If you want to publish a modified version of Telegram:
- You should get your own API key here: https://core.telegram.org/api/obtaining_api_id and create a file called API_KEYS in the source root directory. The contents should look like this:
```
APP_ID = 12345
APP_HASH = aaaaaaaabbbbbbccccccfffffff001122
```
- 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
- Take good care of your users' data and privacy
- Please remember to publish your code too in order to comply with the licenses

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

./gradlew assembleAfatRelease
