从广播接收器启动服务

Question

如果我从Activity开始我的Service，它将正常运行（通过单击按钮）。但是，如果我从BrodcastReceiver开始它不起作用。我究竟做错了什么？ 这里是我的Service代码，BroadcastReceiver

这是我如何做到这一点，它的工作原理：

public class BadgesReceiver extends BroadcastReceiver { 
    private static final String TAG = "BadgesReceiver"; 

    public static final String BADGES_UPDATE_ACTION = BuildConfig.PACKAGE_NAME + ".action.UPDATE_BADGES"; 

    @Override 
    public void onReceive(Context context, Intent intent) { 
     final String action = intent != null ? intent.getAction() : null; 
     Log.d(TAG, "onReceive action: " + action); 
     if (!TextUtils.isEmpty(action) && action.equals(BADGES_UPDATE_ACTION)) { 
      final Intent i = new Intent(context, MyService.class); 
      i.setAction(MyService.UPDATE_BADGES_ACTION); 
      context.startService(i); 
     } 
    } 
}
