Android Service System使用start Sticky重启服务时调用哪个方法

Question

根据此处的 Android 文档:

https://developer.android.com/reference/android/app/Service.html#onStartCommand(android.content.Intent, int, int)

onStartCommand() 仅在用户明确启动服务时触发

当系统启动使用START_STICKY启动的服务时调用哪个方法？

Answer 1

将重新创建服务。

onCreate() 和 onStartCommand() 都会被调用。

来自documentation :

Later the system will try to re-create the service. Because it is in the started state, it will guarantee to call onStartCommand(Intent, int, int) after creating the new service instance; if there are not any pending start commands to be delivered to the service, it will be called with a null intent object, so you must take care to check for this.
