I've integrated SDK 8.5 in my android application and noticed an important issue:
When pressing home button when in the viewfinder, the application still uses 15 to 20% of the CPU until activity's onDestroy() is called.
This doesn't occur if the viewfinder is exited with back key (onPause() and onDestroy() are called in this case)
This is reproduceable easily with the SDK example application: enter image recognition screen, exit by pressing home and check the profiler output..
This is a major issue as it will warm up the phone and consume a lot of battery...!
Thanks for your support,
