回答1:

Make Sure u have the permission in AndroidManifest File :

  <uses-permission android:name="android.permission.RECEIVE_BOOT_COMPLETED" />

Change this to :

@Override
public void onReceive(Context context, Intent intent) {
    Intent serviceIntent = new Intent(context,BackgroundService.class);
    startService(serviceIntent);
    }

回答2:

RECEIVE_BOOT_COMPLETED: Broadcast Action: This is broadcast once, after the system has finished booting. It can be used to perform application-specific initialization, such as installing alarms. You must hold the RECEIVE_BOOT_COMPLETED permission in order to receive this broadcast.
