This is the complete source code and the build instructions for the official alternative Android client for the Telegram messenger, based on the Telegram API and the MTProto secure protocol via TDLib.

• awesome-tgx on Telegram
• APKs and Build Info

• At least 5,34GB of free disk space: 487,10MB for source codes and around 4,85GB for files generated after building all variants
• 4GB of RAM
• macOS or Linux-based operating system. Windows platform is supported by using MSYS (e.g., Git Bash).

• Homebrew
• git with LFS, wget and sed: $ brew install git git-lfs wget gsed && git lfs install

• git with LFS: # apt install git git-lfs
• Run $ git lfs install for the current user, if you didn't have git-lfs previously installed

• Shell with git, wget, and make utilities:
  • MSYS: $ pacman -S make git mingw-w64-x86_64-git-lfs
  • Git Bash:
    1. Download wget, unzip wget.exe and move to your Git\mingw64\bin\
    2. Download make, unzip and copy the contents to your Git\mingw64\ merging the folders, but do NOT overwrite any existing files
• Run $ git lfs install for the current user, if you didn't have git lfs previously initialized

1. $ git clone --recursive --depth=1 --shallow-submodules https://github.com/chrhsnv/awesome-tgx awesome-tgx — clone Telegram X with submodules
2. In case you forgot the --recursive flag, cd into tgx directory and: $ git submodule init && git submodule update --init --recursive --depth=1
3. Create keystore.properties file outside of source tree with the following properties:
   keystore.file: absolute path to the keystore file
   keystore.password: password for the keystore
   key.alias: key alias that will be used to sign the app
   key.password: key password.
   Warning: keep this file safe and make sure nobody, except you, has access to it. For production builds one could use a separate user with home folder encryption to avoid harm from physical theft
4. $ cd tgx
5. Run $ scripts/./setup.sh and follow up the instructions
6. If you specified package name that's different from the one Telegram X uses, setup Firebase and replace google-services.json with the one that's suitable for the app.id you need
7. Now you can open the project using Android Studio or build manually from the command line: ./gradlew assembleUniversalRelease.

• arm64: arm64-v8a build with minSdkVersion set to 21 (Lollipop)
• arm32: armeabi-v7a build
• x64: x86_64 build with minSdkVersion set to 21 (Lollipop)
• x86: x86 build
• universal: universal build that includes native bundles for all platforms.

If you are developing a contribution to the project, you may follow the simpler building steps:

1. $ git clone --recursive https://github.com/chrshnv/awesome-tgx awesome-tgx
2. $ cd tgx
3. Obtain Telegram API credentials
4. Create local.properties file in the root project folder using any text editor:
   

   # Location where you have Android SDK installed
   sdk.dir=YOUR_ANDROID_SDK_FOLDER
   # Telegram API credentials obtained at previous step
   telegram.api_id=YOUR_TELEGRAM_API_ID
   telegram.api_hash=YOUR_TELEGRAM_API_HASH

5. Run $ scripts/./setup.sh — this will download required Android SDK packages and build native dependencies that aren't part of project's CMakeLists.txt
6. Open and build project via Android Studio or by using one of ./gradlew assemble commands in terminal

After submitting a pull request and its initial review, special build including your contribution will be published in @tgx_prs channel, where it can be tested by the community. In case any issues or bugs found, you may push more commits to an existing PR that address them and request to publish a newer build by using comments section of pull request or in @tgx_dev chat.

Here's a list of related PR-welcome TODOs:

• Project path must not affect the resulting .so files, so user & project location requirement could be removed
• When building native binaries on macOS, .comment ELF section differs from the one built with Linux version of NDK. It must be removed or made deterministic without any side-effects like breaking native-debug-symbols.zip (or should be reported to NDK team?)
• Checksums of cold APK builds always differ, even though the same keystore applied and generated inner APK contents do not differ. Real cause must be investigated and fixed, if possible.
  To generate cold build, invoke $ scripts/./reset.sh and $ scripts/./setup.sh --skip-sdk-setup.
  Warning: this will also reset changes inside some of the submodules (ffmpeg, libvpx, webp, opus and ExoPlayer)

PS: Docker is not considered an option, as it just hides away these tasks, and requires that all published APKs must be built using it.
