title: Android install source
body: <p>Is it possible to get the source of install from an <code>Android</code> app?</p>
  
  <p>I mean, I want to see, if the app is installed from the <code>Play Store</code>, <code>Amazon Appstore</code> or via executing an APK.</p>
  
  <p>PS: I think to see it while my app crashes and I was able to send an bug report, that my app was installed via <code>Play Store</code>. How do I get this value?</p>
