Android : Move activity to background in broadcast receiver

Is this possible to move activity to background in broadcast receiver? Here is my code:

@Override
public void onReceive(Context context, Intent intent) {
    if (Intent.ACTION_BOOT_COMPLETED.equals(intent.getAction())) {

            Intent i = new Intent(context, Login.class);
            i.addFlags(Intent.FLAG_ACTIVITY_NEW_TASK);
            context.startActivity(i);
            //I want to move above activity to background
        }
    }

Is this possible to do? I googled it, but I couldn't find right answer. Thanks for any help ;-)
