根据此处的 Android 文档:
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？
最佳答案
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.
