推荐答案

如果你正着手与 startService 服务，那么第一次的的onCreate 方法将被调用，这不要紧，你有多少次启动该服务，但它的方法 onStartCommand（意向，INT，INT）将被称为对于你的startService电话。当你调用 stopService 不管你有多少次叫 startService 服务停止。

if you are starting service with startService then for first time it's onCreate method will be called and it does not matter how many times you have started the service but its method onStartCommand(Intent, int, int) will be called with respect to your startService call. Service stops when you call stopService irrespective of how many times you have called startService.

不要忘了释放资源，线程，当你停止servive。

Don't forget to release the resources, threads when you stop the servive.
