readme: Update and add detailed steps to build instructions (#1865)
Currently, the build instructions are very brief and don't explain the
whole process of setting up the build environment in detail. Thus, add
explicit steps on how to download required tools and prepare then for
compilation.

Translations

The project is translated on Transifex.

Dev

Language mappings are defined in .tx/config, with the second code being the one from transifex. Google play supported languages: https://support.google.com/googleplay/android-developer/table/4419860. Android supported languages: https://stackoverflow.com/questions/7973023/what-is-the-list-of-supported-languages-locales-on-android. If a new language is added on transifex that's not supported, add them to deleteUnsupportedPlayTranslations in app/build.gradle.

Building

These dependencies and instructions are necessary for building from the command line. If you build using Docker or Android Studio, you don't need to set up and follow them separately.

Dependencies

  1. Android SDK and NDK
    1. Download SDK command line tools from https://developer.android.com/studio#command-line-tools-only.

    2. Unpack the downloaded archive to an empty folder. This path is going to become your ANDROID_HOME folder.

    3. Inside the unpacked cmdline-tools folder, create yet another folder called latest, then move everything else inside it, so that the final folder hierarchy looks as follows.

      cmdline-tools/latest/bin
      cmdline-tools/latest/lib
      cmdline-tools/latest/source.properties
      cmdline-tools/latest/NOTICE.txt
      
    4. Navigate inside cmdline-tools/latest/bin, then execute

      ./sdkmanager "platform-tools" "build-tools;<version>" "platforms;android-<version>" "extras;android;m2repository" "ndk;<version>"
      

      The required tools and NDK will be downloaded automatically.

      NOTE: You should check Dockerfile for the specific version numbers to insert in the command above.

  2. Go (see https://docs.syncthing.net/dev/building#prerequisites for the required version)
  3. Java version 11 (if not present in $PATH, you might need to set $JAVA_HOME accordingly)
  4. Python version 3

Build instructions

  1. Clone the project with
    git clone https://github.com/syncthing/syncthing-android.git --recursive
    
    Alternatively, if already present on the disk, run
    git submodule init && git submodule update
    
    in the project folder.
  2. Make sure that the ANDROID_HOME environment variable is set to the path containing the Android SDK (see Dependecies).
  3. Navigate inside syncthing-android, then build the APK file with
    ./gradlew buildNative
    ./gradlew assembleDebug
    
  4. Once completed, app-debug.apk will be present inside app/build/outputs/apk/debug.

NOTE: On Windows, you must use the Command Prompt (and not PowerShell) to compile. When doing so, in the commands replace all forward slashes / with backslashes \.
