title: App icon not being set, it is always showing default green android icon
body: <p>I have followed the following steps as suggested by tutorials and other stack overflow questions:</p>
  
  <ol>
  <li>android:icon="@mipmap/ic_launcher" in the manifest where the app icon is named ic_launcher and all the mipmaps have been appropriately replaced on basis of resolution</li>
  <li>replaced all mipmap images with the the images generated from <a href="https://romannurik.github.io/AndroidAssetStudio/" rel="noreferrer">Android Asset Studio</a></li>
  <li>I have selected the appropriate files in the image asset by right clicking on res.</li>
  <li>I have uninstalled the old app. Rebuilt the app the ans then run</li>
  <li>I have invalidated cache and restarted Android Studio too</li>
  <li>Restarted the mobile</li>
  <li>Added a 512 * 512 pixel image in image asset too.</li>
  </ol>
  
  <p>The problem I suspect is that when I launch the image asset, the default is on clipart and not on image. So everytime the app is run it may be picking up the default clipart icon. </p>
  
  <p>I have also kept the app icon in the toolbar. This changes sometimes. If the app is run again it changes back to the default green android icon.</p>
  
  <p>I have the new android studio 2.1. So is there some problem with it in this regards?</p>
