android - 即使在调用 stopService 后服务继续运行

Question

我有一项服务，每 15 分钟检查一次 Web API 以获取一些信息，然后会收到一条通知。现在，当我单击注销按钮时，我正在执行 stopService 来停止正在运行的服务。我在我的设置中运行的应用程序中没有看到它，我相信它当前没有运行。但我仍然每 15 分钟收到一次通知。这是我的服务。

@Override

这是我如何阻止它。

stopService(i1);

这是 Intent 。您可能会寻找它。

i1 = new Intent(this, BGService.class);

我已经包含了我所有的方法和所有重写的方法供大家查看。你们对造成这种情况的原因有什么想法吗？谢谢!

问题:

I'm not seeing it on my running applications on my settings and I believe it is not currently running

解决方案:

是的，您的 Service 已停止，但 Thread 仍在运行。

只需重写Service 的onDestroy() 方法，如下所述:

    @Override
public void onDestroy() {
    super.onDestroy();
     handler.removeCallbacks(sendWakeLock);

}

希望对您有所帮助!!
