BroadcastReceiver onReceive open dialog

Question

I'm building an android application with BroadcastReceiver and I want to show a dialog when onReceive starts. I want to show the dialog on the phone (show the user a dialog no matter where he is, like the whatsapp dialog when you get a message).

How I can do that?

Thanks!

Answer 1

If you want to show a dialog from inside your onReceive of the BroadcastReceiver, inside your broadcast receiver you may start a transparent activity with an alert dialog and NEVER called setContentView(). The activity will have an transparent view and only the alert dialog will show. Source: show an alert dialog in broadcast receiver after a system reboot
