title: Detect when application is back from background
body: <p>I would like to know when my app is back from background. onResume() is not a good solution, because i have another activities beside the Main Activity, so it can back from background to each of them. The purpose is to use <code>Google analytics</code> and to know when a user is launching the app and also bring it back from the background.</p>
  
  <p>Thank you all and much appreciation.</p>
