Proper way to stop IntentService
提问by malinjir
I'm using an IntentService to upload images to a server. My problem is that I don't know how/when to stop the service. When I call stopself() in onHandleIntent(Intent ..) all Intents which are waiting in the IntentService queue are removed. But I don't want to stop the service from an activity because I want to complete upload proccess even if my application is not running.
我正在使用 IntentService 将图像上传到服务器。我的问题是我不知道如何/何时停止服务。当我在 onHandleIntent(Intent ..) 中调用 stopself() 时，所有在 IntentService 队列中等待的 Intent 都会被删除。但是我不想从活动中停止服务，因为即使我的应用程序没有运行，我也想完成上传过程。

我的问题是我不知道如何/何时停止服务。
IntentServiceautomatically stops itself when onHandleIntent()ends, if no more commands had been sent to it while onHandleIntent()was running. Hence, you do not manually stop an IntentServiceyourself.
IntentServiceonHandleIntent()如果onHandleIntent()在运行时没有向它发送更多命令，则在结束时自动停止。因此，您不会IntentService自己手动停止。
When I call stopself() in onHandleIntent(Intent ..) all Intents which are waiting in the IntentService queue are removed.
当我在 onHandleIntent(Intent ..) 中调用 stopself() 时，所有在 IntentService 队列中等待的 Intent 都会被删除。
Which is why you do not do that.
这就是为什么你不这样做。
But I don't want to stop the service from an activity because I want to complete upload proccess even if my application is not running.
但是我不想从活动中停止服务，因为即使我的应用程序没有运行，我也想完成上传过程。
Then you let the IntentServicestop itself.
然后你让IntentService停止本身。

An IntentServicestops itself when it has no more Intents (jobs) to process. It runs stopSelf(startId)for each Intent(job). Have a look at the IntentServicesource or the Extending the Service Classfrom here http://developer.android.com/guide/topics/fundamentals/services.html
一个IntentService停止本身时，它没有更多的IntentS（作业）来处理。它stopSelf(startId)为每个Intent（作业）运行。查看IntentService源代码或Extending the Service Class从这里http://developer.android.com/guide/topics/fundamentals/services.html
