Is it possible to create multiple PendingIntents with the same requestCode and different extras?

Actually, you don’t “create” PendingIntents. You request them from the Android framework. When you request a PendingIntent from the Android framework, it checks to see if there is already a PendingIntent that matches the criteria you pass as arguments.

android: running a background task using AlarmManager

You’ve created a MediaPlayer instance in your BroadcastReceiver and are trying to control that in onReceive(). This is wrong. You should use a Service to manage and maintain the … Read more

There is a timer that starts running when the device boots up to measure the uptime of the device and this is the type that triggers your alarm … Read more
