My question is simply how can i do a dialog pop up from other application.
I search around and many answer is NO.

However, the messenger like Whaxxapp is exactly doing this. It can pop up an instantly reply while i am playing game, taking picture and etc. (like pausing)

And i had do some research and works,
i am able to create a service which start from my activity (activity A).
And the service is registered a contentobserver, when the observer onchange is fired, it can launch an activity(pendingactivity B) and the activity B which i had set the theme transparent and look like a dialog popup. however, it will also change the background back to my activity A and with the popup as well.

What i want to do is not go back to my activity A and just pop up (or launch the pending activity B) when i receive an onchange. (same as Whaxxapp pop up message with interaction)

Thanks so much.

    You should start Activity B to new task. So when you press back activity A won’t be shown. Add Intent.FLAG_ACTIVITY_NEW_TASK flag to Activity B intent.
