Starting Service from BroadcastReceiver

should be like that:

Intent i = new Intent(context, YourServiceName.class);
context.startService(i);

be sure to add the service to manifest.xml

use the context from the onReceive method of your BroadcastReceiver to start your service component.

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

Don't forget

context.startService(..);
