I have an activity that starts the camera app in secure mode using : 

Intent cameraIntent = new Intent(MediaStore.INTENT_ACTION_STILL_IMAGE_CAMERA_SECURE);

I need to do some processing after the camera app is gone. So in the onResume() , I had written the code to handle the POST processing (This is because, let say the camera app is launched in ParentActivity, then after camera app finishes, the onResume() of ParentActivity will be called). The program is working fine for the camera closing via Back button but when the camera is closed by Home button or Recent button, the POST processing is not getting called. So where can I place the code of POST processing that will get called everytime the user moves away from the camera (via Home , Recent, Back buttons) . I cant change the camera activity code as the camera application is not written by me , so I can't put the POST processing inside the onPause() of the camera activity. Is there anyway, I can override the onPause() of an Activity that I am starting by startActivity ?

  • If the user navigates away from the camera app without taking a picture, what do you have to post-process, since you will not have a picture? – CommonsWare Jul 06 '15 at 13:03
  • The camera is a part of Lockscreen, so even when the user walks away from the camera withouyt doing anything, I have to reenable the lock screen – user2436032 Jul 06 '15 at 13:04
