73.5 Adding a Broadcast Receiver

The final step in the project is to add an action to the PiP window. The purpose of this action is to display a Toast message containing the name of the currently playing video. This will require some communication between the PiP window and the activity. One of the simplest ways to achieve this is to implement a broadcast receiver within the activity, and the use of a pending intent to broadcast a message from the PiP window to the activity. These steps will need to be performed each time the activity enters PiP mode so code will need to be added to the onPictureInPictureModeChanged() method. Locate this method now and begin by adding some code to create an intent filter and initialize the broadcast receiver:
