Hi Xavier,
I had a similar problem with the activity state and screen rotation. I
managed to fix this after adding the following attributes for the crosswalk
activity in the android manifest:
android:launchMode="singleTask"
android:configChanges="orientation|screenSize"
Hope this helps :)
Regards,
Andreas
