I didn't change much.
In the permission tab i have only:
In app browser and splash-screen enabled (but previous exports with more permission worked as well, so i don't your problem is there)
In the build tab under android-crosswalk:
I filled in the normal values for app id/name/desc etc.
The app version and version code i had to change on the second export so google play will let me upload the file.
Domain access i left with *
and cli version with 3.3
I checked the full screen box
install location: default
i check the signed box
and i used crosswalk beta
I also uploaded icons and splash screen images (all images must be located inside the www directory of the project before selecting them.
As for exiting the app with the back button, that's another strange thing, it exits with the back button regardless to any events calling it, i think it's something new and built-in xdk, i have only one layout in this project, so i don't have any events to switch layouts on back button or anything, but i believe if i did, it would close the app as well, which is not a good thing at all...
Just to make it clear, i have an event on back button/touch sprite - browser close.
This event only works if var canPlay = 0
but it closes the apps even when this var is = 1
I hope this helps you guys.
