title: Application icon not showing after Gradle plugin update to 3.0
body: <p>I want to upgrade my Android Plugin for Gradle from 2.3.3 to 3.0.1. I could fix all the errors following the <a href="https://developer.android.com/studio/build/gradle-plugin-3-0-0-migration.html?utm_source=android-studio" rel="nofollow noreferrer">Migration Guide</a>. My problem now is that on Android Nougat (24) and Android Marshmallow (23) application icon is replaced with the default robot icon. </p>
  
  <p>Could you help me find the reason for the problem. Previously icon was shown and I don't see logical reason why not now.</p>
  
  <p>I tried all suggestions <a href="https://stackoverflow.com/questions/4776933/android-application-icon-not-showing-up">here</a> without success.</p>
  
  <p>Here is my Manifest file: </p>
