Calling camera app recreates android activity

问题:

I am working on a tabbed activity which is implemented using ActivityGroup. When I call the camera app and returns back its always calling onCreate() and recreates the activity. Because of this the callback to onActivityResult is having a null data.

I am adding this inside manifest file. But no change.

android:screenOrientation="portrait"
android:configChanges="orientation|keyboardHidden"

I am having this issue only on samsung galaxy s3. I have tested the same on galaxy s2,HTC, galaxy nexus. All devices works fine.

How can I do this properly?

Thanks
