What is the equivalent of onBackPressed() for overriding and taking control of the Recent Apps button on Android?

Question

This is the method to access Android's Back button.

@Override
public void onBackPressed() {
// do something on back.
return;
}

I want to do something similar for the Recent Apps button (the right most one)

Answer 1

You can really change the functionality of the AppButton programatically except if you are creating your own custom launcher but you can still detect if the AppButton is pressed in your app.

sample:

@Override
public void onWindowFocusChanged(boolean hasFocus) {
    super.onWindowFocusChanged(hasFocus);

    if(!hasFocus)
        Log.d("APP BUTTON", "APP BUTTON");
}
