Android : Firemonkey TTakePhotoFromCameraAction.OnDidFinishTaking cause my apps to restart

sorry for wrong title, this is my first question here.

So i'm developing a mobile apps to read barcode. In my apps there is a login form before the main form loaded. On the main form i put action list and add TTakePhotoFromCameraAction action to open the device camera and take photo using it. So far is working well, i'm following the tutorial in http://docwiki.embarcadero.com/RADStudio/XE6/en/Mobile_Tutorial:_Taking_and_Sharing_a_Picture,_and_Sharing_Text_(iOS_and_Android).

But after pressing the yes button after taking photo, my apps return to the login form where i assume it is restarted while it should be back to the main form where i call the action. So what am i missing here. The code i use is the same as the tutorial above.

I'm using Delphi XE 6 update 1

Please let me know if i miss some information you need. Thanks in advance
