I have a GDK application that works fine in XE12, but now crashes in XE16 after switching to GDK: 19. In particular, calling openOptionsMenu() in Activity (in this case, to open the options menu on the Live Card) calls BadTokenExceptions.
Logcat Output:

A method in a service that binds an action to a live map:
@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 already running } return START_STICKY; // No idea what this does. Your guess is as good as mine. }
And the problem is:
/** * 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! } }
Clicking on a live card causes an immediate crash, and the output from Logcat above is reset. Which is strange, if the commented openOptionsMenu () is uncommented and the existing openOptionsMenu () is commented out, the first click will actually open the menu. The second attempt to open the menu will fail, with the same Logcat output (the BadTokenException exception is the main exception instead of the internal exception in RuntimeException).
