啟動服務

啟動服務非常簡單，只需在 Activity 中呼叫 startService 即可：

Intent intent = new Intent(this, MyService.class);  //substitute MyService with the name of your service
intent.putExtra(Intent.EXTRA_TEXT, "Some text"); //add any extra data to pass to the service

startService(intent); //Call startService to start the service.
