I have an Android project in which I have one Unity activity integrated in it. I’m running into an issue when i call finish() from within unity activity to return the main activity. It causes the entire process to be killed (it sends signal 9 – SIGKILL).
This is how I call the java method that handles the back button from Unity C# code:
void Update ()
{
if (Input.GetKeyDown (KeyCode.Escape)) {
AndroidJavaClass jc = new AndroidJavaClass ("com.unity3d.player.UnityPlayer");
AndroidJavaObject jo = jc.GetStatic<AndroidJavaObject> ("currentActivity");
jo.Call ("goBack");
}
}
And I call finish from the Unity activity once I export my project as an Android project:
void goBack(){
finish();
}
