Question

I have a chat app, when my app is in the background (called HOME button), my app is running countiniously…

When on my app a user initiate a private chat with me, i d like to showing up a notification.

So how I can check in my app, that my app is in the background?

I think the easiest way is to use onPause in your chat activity:

@Override
protected void onPause() {
    super.onPause();
    // Another activity is taking focus (this activity is about to be "paused").
    //set a flag somewhere (in your service?) to say activity has been minimised
}

See the Activity lifecyle docs for more details.
