title: Android app is not running on other device
body: <p>i just made a simple android app with 6 buttons. Each button on click opens a new activity. I installed the app on my device via USB cable from <code>Android studio</code> and it runs fine on my device.</p>
  
  <p>But here rises the problem, when I installed the app on my friends device after sharing via <code>SHAREit</code> the app installed on his device but did not run.</p>
  
  <p>What could be the reason for this? And how can I solve this?</p>
  
  <p>Please help. Thank you</p>
