Llamar openOptionsMenu () en XE16 causa WindowManager.BadTokenException

Tengo una aplicación GDK que funcionó bien en XE12, pero ahora se bloquea en XE16 después de la transición a GDK: 19. En particular, llamar a openOptionsMenu() en una Actividad (en este caso, para abrir un menú de opciones en una Live Card) causa BadTokenExceptions.

Método en servicio que enlaza la actividad a la tarjeta activa:

 @Override public int onStartCommand(Intent intent, int flags, int startId) { // This method is called whenever the Glassware is invoked via voice commands or the OK Glass menu. if (mLiveCard == null) { Log.d(TAG, "Connecting mLocationManager"); Criteria criteria = new Criteria(); criteria.setAccuracy(Criteria.ACCURACY_COARSE); PinDropLocationListener listener = new PinDropLocationListener(); locationListeners.add(listener); mLocationManager.requestSingleUpdate(criteria, listener, null); mLiveCard = new LiveCard(getBaseContext(), LIVE_CARD_TAG); mLiveCard.setViews(new RemoteViews(getPackageName(), R.layout.activity_waiting)); mLiveCard.attach(this); // Prevent this Service from being killed to free up memory Intent menuIntent = new Intent(this, MenuActivity.class); // Since menus can only be attached to Activities, we create an activity to own and launch the menu. menuIntent.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK | Intent.FLAG_ACTIVITY_CLEAR_TASK); mLiveCard.setAction(PendingIntent.getActivity(this, 0, menuIntent, 0)); // This Intent will be fired whenever the LiveCard is tapped. Log.d(TAG, "Publishing LiveCard"); mLiveCard.publish(PublishMode.REVEAL); // Add the LiveCard to the Timeline and switch to it Log.d(TAG, "Done publishing LiveCard"); } else { mLiveCard.navigate(); // Switch to the app if it's already running } return START_STICKY; // No idea what this does. Your guess is as good as mine. } 

Y la problemática Actividad:

 /** * Activity showing the options menu. */ public class MenuActivity extends Activity { // This is technically an Immersion! // Because Services have no UI, we need to open this Activity, which in turn opens its menu! PinDropService.MenuBinder mBinder; private static String TAG = "PinDropMenu"; boolean hasLocation; /* * Links this Activity to the Service that spawned it, so the Menu can send and receive information */ private ServiceConnection mConnection = new ServiceConnection() { @Override public void onServiceConnected(ComponentName name, IBinder service) { if (service instanceof PinDropService.MenuBinder) { mBinder = (PinDropService.MenuBinder)service; hasLocation = mBinder.hasLocation(); Log.d(TAG, hasLocation ? "Received has location" : "Received no location"); //openOptionsMenu(); } } @Override public void onServiceDisconnected(ComponentName name) {} }; @Override protected void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); bindService(new Intent(this, PinDropService.class), mConnection, 0); } @Override public void onResume() { super.onResume(); openOptionsMenu(); } @Override public boolean onCreateOptionsMenu(Menu menu) { MenuInflater inflater = getMenuInflater(); inflater.inflate(R.menu.pindropmenu, menu); return true; } @Override public boolean onPrepareOptionsMenu(Menu menu) { if (!hasLocation) { menu.findItem(R.id.directions).setVisible(false); menu.findItem(R.id.remember).setVisible(false); } else { menu.findItem(R.id.directions).setVisible(true); menu.findItem(R.id.remember).setVisible(true); } return true; } @Override public boolean onOptionsItemSelected(MenuItem item) { // Handle item selection. switch (item.getItemId()) { case R.id.directions: mBinder.startNavigation(); return true; case R.id.remember: mBinder.addToTimeline(); // TODO: Add Mirror functionality! return true; case R.id.stop: // IT IS CRITICALLY IMPORTANT TO ADD THIS OR THE GLASSWARE CAN'T BE KILLED IN USERSPACE! stopService(new Intent(this, PinDropService.class)); return true; default: return super.onOptionsItemSelected(item); } } @Override public void onOptionsMenuClosed(Menu menu) { // Nothing else to do, closing the Activity. finish(); } @Override public void onStop() { super.onStop(); unbindService(mConnection); // Don't leak Services! } } 

Golpear la tarjeta en vivo provoca un bloqueo inmediato y la salida Logcat anterior se descarga. Lo extraño es que si el openOptionsMenu () comentado es uncommented y el openOptionsMenu () existente es comentado, el primer toque realmente abrirá el menú. El segundo intento de abrir el menú fallará, con salida Logcat similar (la excepción BadTokenException es la excepción principal en lugar de una excepción interna en RuntimeException).

Como dijo Petey , pero necesita anular onAttachedToWindow() además de onResume() . Mi código ahora se parece a algo así:

 private boolean isAttached = false; @Override public void onAttachedToWindow() { super.onAttachedToWindow(); this.isAttached = true; openOptionsMenu(); } @Override public void onResume() { super.onResume(); if (this.isAttached) openOptionsMenu(); }

"Las muestras se han actualizado también – de Compass:"

 @Override public void onAttachedToWindow() { super.onAttachedToWindow(); mAttachedToWindow = true; openOptionsMenu(); }
