set Media Notification Tap Intent
Sets the android.app.PendingIntent to be triggered when a user taps on a media notification associated with the player.
This allows host apps to specify a custom activity to launch when a user taps the media notification.
It's strongly recommended that the activity being referenced by the PendingIntent is declared with a SINGLE_TOP launch_mode in AndroidManifest.xml. This helps to avoid launching a new, different instance of the activity that's currently hosting the video playback.
Parameters
pending Intent
PendingIntent to be triggered upon notification tap.
