我在应用程序中设置onStart方法有问题。它总是有一个删除线，说“这个方法在API 5级被淘汰了。我需要onStart，而不是onStartCommand。

我该如何解决？

MyNotificationService.java

import android.app.Service;

import android.content.Intent;

import android.os.IBinder;

import android.widget.Toast;

public class MyNotificationService extends Service {

@Override

public IBinder onBind(Intent arg0) {

// TODO Auto-generated method stub

return null;

}

@Override

public void onCreate() {

// TODO Auto-generated method stub

super.onCreate();

Toast.makeText(this, "OnCreate()", Toast.LENGTH_SHORT).show();

}

@Override

public void onDestroy() {

// TODO Auto-generated method stub

super.onDestroy();

Toast.makeText(this, "OnDestroy()", Toast.LENGTH_SHORT).show();

}

@Override

@Deprecated

public void onStart(Intent intent, int startId) {

// TODO Auto-generated method stub

super.onStart(intent, startId);

}

}

}

@Override

public boolean onCreateOptionsMenu(Menu menu) {

// Inflate the menu; this adds items to the action bar if it is present.

getMenuInflater().inflate(R.menu.reminder, menu);

return true;

}

}
