Ich habe eine GDK-App, die in XE12 funktionierte, aber jetzt in XE16 abstürzt nach dem Übergang zu GDK: 19. Insbesondere verursacht das Aufrufen von openOptionsMenu() in einer Aktivität (in diesem Fall zum Öffnen eines Optionsmenüs auf einer Live-Karte) BadTokenExceptions.Aufruf von openOptionsMenu() in XE16 verursacht WindowManager.BadTokenException
Logcat Ausgang:

die Live-Karte Ursachen Tapping ein sofortiger Absturz, und die obige Logcat-Ausgabe wird ausgegeben. Was komisch ist, ist, dass, wenn das auskommentierte openOptionsMenu() unkommentiert ist und das existierende openOptionsMenu() auskommentiert ist, das erste Tippen das Menü öffnet. Der zweite Versuch, das Menü zu öffnen, schlägt mit ähnlicher Logcat-Ausgabe fehl (die BadTokenException ist die Hauptausnahmebedingung anstelle einer inneren Ausnahme bei RuntimeException).
