GameActivity

GameActivity is an Android Activity modeled on the API of NativeActivity, but with a few changes to make it a better starting point for game developers.

• It inherits from androidx.appcompat.app.AppCompatActivity - allowing you to use Jetpack components architecture (and still use some of the newer platform features on older Android devices).
• It renders into a SurfaceView that allows you to interface with any other Android UI element.
• It handles events like a Java activity would do, allowing any Android UI element (like a text edit, a webview, an ad or a form) to work as usual, but still exposes the events to your game using a C interface that makes them easy to consume in your game loop.
• It offers a C API similar to NativeActivity, and to the android_native_app_glue library.

Build the GameActivity AAR from sources

Use the script to build the GameActivity AAR and inject the C++ source files.

• cd GameActivity && ./build.sh

Note that this is a temporary workaround (in the future, running ./gradlew :GameActivity:assembleRelease should be enough).

The AAR is outputed in out/outputs/aar/GameActivity.aar (out directory being where you cloned the Android Game SDK). It contains GameActivity, both the Java class and its C++ implementation, and the “android_native_app_glue” library.

Integrate GameActivity AAR to your build

Refer to the integration guide for now. Link to it and other documentation will be added here later.
