Android Java Libraries in UE4 Game (OUYA SDK, Google Play Game Services, etc.)

Can I ask what functions are you calling in GameActivity.java and from what methods? I’m adding to the PR which adds a listener to expose more Java events to UE4 plugins.

Of course, I need to add a bunch of comments for each of these Activity methods.

You can see with these added callbacks, you’ll have access to invoke your JAR/Java methods from your UE4 plugin without modifying the engine’s GameActivity.java.
Added GameActivity event callbacks for UE4 plugins. · tgraupmann/UnrealEngine_JNI_OnLoad@8e6ff62 · GitHub

Here is the logcat showing the example log lines.

I have two outstanding PRs.

Added a callback for the JNI_OnLoad event to be used by UE4 plugins - https://github.com/EpicGames/UnrealEngine/pull/2313
Add Android Input callback - https://github.com/EpicGames/UnrealEngine/pull/2314

The result of all this is that I’ll be able to release a Cortex/OUYA plugin to the marketplace. So a game developer would just need to get an example project like Tappy Chicken and then add the Cortex plugin from the marketplace. The user builds for Android and the game would work with a controller on the Forge TV Android console. And that’s without touching any code.

Thank you very much! I have solved my problem. The problem is that I imported a wrong package. ;)
