Analog Clock Window crashes on startup on Android

Start the "Analog Clock Window" example on an Android device. It shuts down on start-up.

The output in adb logcat seems to indicate that it's crashing when initializing the QPlatformBackingStore:

I/DEBUG ( 123): 72e76df4 72c8aa69 /data/local/tmp/qt/lib/libQt5Gui.so (QPlatformBackingStore::QPlatformBackingStore(QWindow*)+24)
