在服务的onStartCommand()方法中，应使用START_STICKY标志来确保服务正常运行。同时，务必使用多线程来避免服务占用UI线程，导致锁定UI。以下是一个示例代码：

public class MyService extends Service {

private boolean isRunning;

@Override
public void onCreate() {
    super.onCreate();
    isRunning = false;
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {
    isRunning = true;

    new Thread(new Runnable() {
        @Override
        public void run() {
            // Do something here...
            stopSelf();
        }
    }).start();

    return START_STICKY;
}

@Override
public void onDestroy() {
    super.onDestroy();
    isRunning = false;
}

}
