## Build

### Dependencies

- Android SDK Platform & Build-Tools 34.
- Android NDK (Side by side) 25 & CMake 3.22.1, they can be installed using SDK Manager in Android Studio or `sdkmanager` command line.
- [KDE/extra-cmake-modules](https://github.com/KDE/extra-cmake-modules)
- GNU Gettext >= 0.20 (for `msgfmt` binary; or install `appstream` if you really have to use gettext <= 0.19.)

### How to set up development environment

Prerequisites for Windows

- Enable [Developer Mode](https://learn.microsoft.com/en-us/windows/apps/get-started/enable-your-device-for-development) so that symlinks can be created without administrator privilege.

- Enable symlink support for `git`:

```shell
git config --global core.symlinks true
```

First, clone this repository and fetch all submodules:

```shell
git clone [email protected]:fcitx5-android/fcitx5-android.git
git submodule update --init --recursive
```

On Windows, you may need to regenerate symlinks to submodules.

Run in PowerShell:

```powershell
Remove-Item -Recurse app/src/main/assets/usr/share, plugin/hangul/src/main/assets/usr/share/libhangul, plugin/chewing/src/main/assets/usr/share/libchewing, plugin/jyutping/src/main/assets/usr/share/libime
```

Or Command Prompt:

```bat
RD /S /Q app\src\main\assets\usr\share plugin\hangul\src\main\assets\usr\share\libhangul plugin\chewing\src\main\assets\usr\share\libchewing plugin\jyutping\src\main\assets\usr\share\libime
```

Then let `git` regenerate symlinks:

```shell
git checkout -- .
```

Install `extra-cmake-modules` and `gettext` with your system package manager:

```shell
# For Arch Linux (Arch has gettext in it's base meta package)
sudo pacman -S extra-cmake-modules

# For Debian/Ubuntu
sudo apt install extra-cmake-modules gettext

# For macOS
brew install extra-cmake-modules gettext

# For Windows, install MSYS2 and execute in its shell (UCRT64)
pacman -S mingw-w64-ucrt-x86_64-extra-cmake-modules mingw-w64-ucrt-x86_64-gettext
# then add C:\msys64\ucrt64\bin to PATH
```

Install Android SDK Platform, Android SDK Build-Tools, Android NDK and cmake via SDK Manager in Android Studio:

### Trouble-shooting

- Android Studio indexing takes forever to complete and cosumes a lot of memory.

Switch to "Project" view in the "Project" tool window (namely the file tree side bar), right click `lib/fcitx5/src/main/cpp/prebuilt` directory, then select "Mark Directory as > Excluded". You may also need to restart the IDE to interrupt ongoing indexing process.

- Gradle error: "No variants found for ':app'. Check build files to ensure at least one variant exists." or "[CXX1210] /CMakeLists.txt debug|arm64-v8a : No compatible library found"

Examine if there are environment variables set such as `_JAVA_OPTIONS` or `JAVA_TOOL_OPTIONS`. You might want to clear them (maybe in the startup script `studio.sh` of Android Studio), as some gradle plugin treats anything in stderr as errors and aborts.

## Nix

Appropriate Android SDK with NDK is available in the development shell. The `gradlew` should work out-of-the-box, so you can install the app to your phone with `./gradlew installDebug` after applying the patch mentioned above. For development, you may want to install the unstable version of Android Studio, and point the project SDK path to `$ANDROID_SDK_ROOT` defined in the shell. Notice that Android Studio may generate wrong `local.properties` which sets the SDK location to `~/Android/SDK` (installed by SDK Manager). In such case, you need specify `sdk.dir` as the project SDK in that file manually, in case Android Studio sticks to the wrong global SDK.
