Android, how to determine if a reboot occurred?

Question

How would I programmatically determine when an android device has rebooted (whether on its own, or user initiated) ?

Answer 1

This snippet starts an Application automatically after the android-os booted up.

in AndroidManifest.xml (application-part):

// You must hold the RECEIVE_BOOT_COMPLETED permission in order to receive this broadcast.

In Java Class

 public class BootUpReceiver extends BroadcastReceiver{

            @Override
            public void onReceive(Context context, Intent intent) {
                    Intent i = new Intent(context, MyActivity.class);  
                    i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
                    context.startActivity(i);  
            }

}
