Code for detecting when you leave an Android app

Further to Detecting whether an Android app is stopping (or starting), I implemented code to decide when you are leaving or entering my game Rabbit Escape.

The relevant class is called Lifecycle2SoundEvents. (Yes, it’s a terrible name. Yes, I spent a long time trying to name it, and this is the best I came up with.)

And the tests, which are in TestLifecycle2SoundEvents, look like this:

@Test
public void Press_the_home_button_api10_causes_pause()
{
    Tester t = new Tester( activity1 );

    t.in.onSaveInstanceState( activity1 );
    t.in.onPause( activity1 );
    t.in.onStop( activity1 );

    // When we press home, we must at least pause (really we stop)
    t.assertPaused();
}

which I was reasonably pleased with, because they match my original blog post Order of Android Activity lifecycle events fairly well, without too much noise.
