Could you post your exact configuration from your AndroidManifest for the activities that you are calling from and returning a result from?
The reason I ask is that I am struggling with a couple of activities in my app. One should be calling the other using StartActivityForResult but I am getting the dreaded 'Activity is launching as a new task, so cancelling activity result' problem. Neither of my activities are configured in any special way... no weird launchmode or anything but yet it still fails to work for me. Cheers.
