title: Ionic2: Package com.my.app has no certificates at entry AndroidManifest.xml
body: <p>I created one application using Ionic2 and when i run the command <code>ionic cordova run android --prod --release</code> I am getting an error</p>
  
  <pre><code>Failure [INSTALL_PARSE_FAILED_NO_CERTIFICATES: Package /data/app/vmdl
  971492117.tmp/base.apk has no certificates at entry AndroidManifest.xml]
  </code></pre>
