title: Check if android app has a newer version on playStore
body: <p>I want to know if it is possible to check if the app that the user is running is the latest version that is available at Google PlayStore. I have read some answers and they say that this is not possible, but I see some apps that do this. </p>
  
  <p>Can someone tell me how can I do this? I can see that this is possible.</p>
