Extending GameActivity Bridge

Shows how to expand GameActivity C++ bridge files.

Unity doesn't provide a way to add additional C++ files into GameActivity (libgame.so), thus this project uses Assets\Editor\PostProcessor.cs to copy ExtraSourceFiles contents to <gradle_project>\unityLibrary\src\main\cpp\GameActivity\CustomFolder.

Check MyFile.cpp, it does few things:

  • Register to GameActivity's input event, and call SendMessage whenever touch event is down
  • Register to GameActivity's resume event, and call SendMessage whenever app is resumed

Quick Steps

  • Open Unity project
  • Build & Run
  • Tap on screen, "Tap at X x Y" should appear on the screen
  • Pause/Resume app, "Resume caught" should appear on the screen

You can register to variaty of things in GameActivity native bridge, and peform a custom logic.

Check unityLibrary\src\main\cpp\GameActivity\UGAEvents.h for full list of available events.
