Working through rebuild, it seems to be necessary to update minor version number, prior to running build, to persuade GooglePlay dashboard to accept the new APKs
Update: changing the version code on the Project/Build Settings/Crosswalk for Android page does _not_ seem to fix it. Still rejected by GooglePlay for having same version number...
On examination the Crosswalk build seems to be failing to take the updated version numbers into account (the APK coming out has same version number as previous, despite uploading all the source again during build)
Any ideas ? Will continue to work backwards towards Construct2...
Further Update:
XDK build process is broken, I think... It runs, but just FAILS to transfer the updated version number from Projects/Build Settings as described above. IntelRobert please advise how to force XDK to update the version number in the output .apk files
My apologies if this is somehow obvious - I've searched around the web a bit and other people seem to be reporting same problem with XDK
Final(!) Update:
Worked after restart XDK. Suspect problem was me not the s/w. Definitely messy getting GooglePlay to accept updated apks though. Put both x86 and arm versions.
Thank you for your time and help.
