How do I get a media projection manager without disturbing the current foreground process, except to ask for permission?

Question

Problem: I have a screenshot app that uses a floating overlay service for controls, and screen cast API Media Project Manager to get access to the screen. Sometimes when a d

Answer 1

I have a continues running service so i declared a one static variable inside the service and use it when user click my floating button (like chatheads).

public static  Intent data = null;  //declaration 

then when first time user open the app I am asking for the permission and setting the value of the data in following way.

     @Override
        protected void onActivityResult(int requestCode, int resultCode, Intent data) {

 if(requestCode == 4){
               Log.d(TAG, "onActivityResult: for Screen Capture");
               if(resultCode == RESULT_OK)
               {
                   Log.d(TAG, "onActivityResult: Permission Granted");
                WindowChangeDetectingService.data = (Intent) data.clone();
                screenCapturePermission = true;
                   updateUI();
               }else
               {
                   Log.d(TAG, "onActivityResult: Permission Deined");
                   screenCapturePermission = false;
                   updateUI();
                   SnackBar screenCapturePermissionSnackbar = new SnackBar(this, "This Permission is needed.", "Grant", new View.OnClickListener() {
                       @Override
                       public void onClick(View v) {
                           takeScreenCapturePermission();
                       }
                   });
                   screenCapturePermissionSnackbar.setDismissTimer(2000);
                   screenCapturePermissionSnackbar.show();

               }
           }
    }

Finally when user clicks on the floating Overlay Button, first check value of the data.

 if(WindowChangeDetectingService.data == null)
        {
            Log.d(TAG, "basicSetup: Asking permission again");
            //open app again
        }else
        {
            Log.d(TAG, "basicSetup: Getting permission for the object");
            readPermissionObject();
        }

Implementation of readPermissionObject is as follows

 private void readPermissionObject()
    {
       Intent data =  WindowChangeDetectingService.getData();
        mMediaProjectionManager  = (MediaProjectionManager) getSystemService(Context.MEDIA_PROJECTION_SERVICE);
        startProjection(Activity.RESULT_OK,data);
    }

Thanks to @netsplit for giving info about data.clone(); .
