Camera always returns resultCode as 0

Question

I am trying to develop using camera in my android application.

The problem is that the camera always returns a result code of 0, irrespective of if I press done or c

Answer 1

The issue (in android >= 5.0) might be with singleInstance mode.

if you have your activity launchMode set to singleInstance, then in android < 5.0 you will receive cancelled result immediately. In android >=5.0 you will have resultCode == Activity.RESULT_CANCELED.

Try using launchMode = singleTask. It is much like singleInstance, but allows other activities to be launched on the task.
