Supported Permission Names:

  • geolocation: Access to device location
  • notifications: Display notifications
  • camera: Access to camera
  • microphone: Access to microphone
  • persistent-storage: Use persistent storage
  • push: Receive push messages
  • screen-wake-lock: Keep screen on

Usage:


 public class MyPage extends HtmlPage implements PermissionsListener
 {
     @Override
     protected void createBody(Body body)
     {
         // Check geolocation permission status
         PermissionsApi.query(this, "geolocation");
     }

     @Override
     public void onEvent(PermissionStatusEvent event)
     {
         String permission = event.getPermissionName();
         String state = event.getState();

         switch (state)
         {
             case "granted":
                 // Permission granted, can use the feature
                 break;
             case "prompt":
                 // User will be prompted when feature is used
                 break;
             case "denied":
                 // Permission denied, feature unavailable
                 break;
         }
     }
 }
