How to use putExtra() with FLAG_ACTIVITY_REORDER_TO_FRONT in Android Apps?

Question

I have an application, call "App1". In my App1 I invoke Camera application.

intent = new Intent(Intent.ACTION_MAIN); intent.setComponent(new ComponentName("com.android.camera","com.android.camera.Camera")); startActivity(intent); 

After that, I use FileObserver to listen whether user take a photo. When this happens I call

Context ctx = App1.this.getApplicationContext(); Intent j = new Intent(ctx, App1.class); j.setFlags(Intent.FLAG_ACTIVITY_REORDER_TO_FRONT); j.putExtra("type", 1); startActivity(j); 

It works, I mean it gets my application to front how I leave it, however I need to pass an integer, which is called "type". I think, my application will call "onResume()" but how can I get that extra integer. This type of passing didn't do anything in my application.

There's Bundle savedInstanceState in onCreate method, but there is no such a thing in onResume method. So, I need your help to solve this problem. Thanks in advance.

You need to override Activity.onNewIntent() method.

@Override protected void onNewIntent(Intent intent) {     super.onNewIntent(intent);     setIntent(intent); } 

After onNewIntent() is called, the normal onResume() lifecycle will follow. Alternatively, you can write your code in onNewIntent() itself.
