title: Unfortunately, Package Installer has stopped while requesting permission in Marshmallow
body: <p>I am trying to request permission to seek permission to read storage. After recent Android Studio upgrade, I started getting error "Unfortunately, Package Installer has stopped" while requesting permission and the permission request dialog does not come up.</p>
  
  <p>Here is the code snippet where I am requesting the permission</p>
  
  <pre><code>    int readPermission = ContextCompat.checkSelfPermission(this, Manifest.permission.READ_EXTERNAL_STORAGE);
      int writePermission = ContextCompat.checkSelfPermission(this, Manifest.permission.WRITE_EXTERNAL_STORAGE);
      if (readPermission != PackageManager.PERMISSION_GRANTED || writePermission != PackageManager.PERMISSION_GRANTED) {
          ActivityCompat.requestPermissions(this,
                  new String[]{Manifest.permission.READ_EXTERNAL_STORAGE, Manifest.permission.WRITE_EXTERNAL_STORAGE},
                  REQUEST_READWRITE_STORAGE);
      }
  }
  </code></pre>
