java - 服务泄露了最初在此处注册的 IntentReceiver。您是否错过了对 unregisterReceiver() 的调用？

Question

我正在使用前台 Android Service 通过 REST API 通过 Retrofit 请求资源，作为每 60 秒的计时器。此类服务也在与应用程序不同的进程中运行，这是必要的，这样 Android 就不会在进入打盹模式时终止它。

public class ResourceService extends Service {

   ...

   private BroadcastReceiver mReceiver;

   @Override
   public void onCreate() {
      super.onCreate();
      // create mReceiver (BroadcastReceiver)
      // create intentFilter (IntentFilter)     
      registerReceiver(mReceiver, intentFilter);
   }

   ...
   @Override
   public int onStartCommand(Intent intent, int flags, int startId) {
      // main logic
   }

   @Override
   public void onDestroy() {
      super.onDestroy();
      unregisterReceiver(mReceiver);        
   }
}

当我注销应用程序时，onDestroy() 方法被调用，所以 unregisterReceiver() 也被调用。应用程序按预期进入登录 Activity ，服务成功停止。但是，logcat 出现以下异常:

我看到一个similar answer关于主题，但它指的是 Activity 。这样的回答声明 unregisterReceiver() 应该放在 onPause() 方法中，但是在 Service 父类(super class)中没有这样的方法我可以覆盖。

有人知道上述错误的原因是什么吗？

提前谢谢你。

在onstartcommand中调用unregisterReceiver(locationReceiver)
