title: storage permissions not being asked
body: <p>I have added to the manifest files these permissions </p>
  
  <pre><code>&lt;uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" /&gt;
  &lt;uses-permission android:name="android.permission.INTERNET" /&gt;
  &lt;uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" /&gt;
  
  &lt;uses-feature android:name="android.hardware.location.gps" /&gt;
  
  &lt;uses-permission android:name="com.google.android.providers.gsf.permission.READ_GSERVICES" /&gt;
  &lt;uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE" /&gt;
  &lt;uses-permission android:name="android.permission.READ_EXTERNAL_STORAGE" /&gt;
  </code></pre>
  
  <p>But when the user installs the app the only permission he is being asked and allows is <strong>location</strong>.</p>
  
  <p>I also want to ask the user for storage permission.How is this possible?</p>
