title: Can not resolve symbol on calendar write permission request
body: <p>I'm trying to get the users permission in android to write and read to the calendar. However I get an error on the following code:</p>
  
  <pre><code>    if (ActivityCompat.checkSelfPermission(this, Manifest.permission.READ_CALENDAR) != PackageManager.PERMISSION_GRANTED) {
          ActivityCompat.requestPermissions( this, new String[] {  Manifest.permission.READ_CALENDAR  },
                  MY_PERMISSIONS_REQUEST_READ_CALENDAR);
      }
  </code></pre>
  
  <p>It says: can not resolve symbol MY_PERMISSIONS_REQUEST_READ_CALENDAR.
  I can't quite figure out what it's supposed to be.</p>
