Android开发连接本地Mongodb出现deprecated提示

开发环境是Eclipse+Android SDK+Mongodb+mongo-java-driver
Android的API是8(2.2),最低支持的是1.5,最高支持的是4.4。
Mongodb是用2.6.6
mongo-java-driver是2.13.0-rc2

我是做一个简单的学生资料录入的app。
原理是通过点击 save的button,触发SaveButton_Click,然后SaveButton_Click会把对应的
EditText的内容转换成一个mongodb的文档写入数据库。

编码提示mongo的构造方法已经deprecated,
new Mongo();
new Mongo("localhost");
new Mongo("localhost", 27017);
new Mongo(new ServerAddress("localhost"));

上述4种debug软件会有提示,在模拟器运行也会报错。如何才能解决呢?

MainActivity.java的代码:

package com.example.testing;

import android.support.v7.app.ActionBarActivity;
import android.os.Bundle;
import android.view.Menu;
import android.view.MenuItem;
import android.view.View;
import android.widget.*;

import com.mongodb.*;

public class MainActivity extends ActionBarActivity {

Button button;
int count=0;
String studentname;
String studentnum;
String studentage;
String studentsexual;
Mongo conn;
DB db;
DBCollection coll;
BasicDBObject doc;

@Override
protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);
    button = (Button)findViewById(R.id.saveButton);
}

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.main, menu);
    return true;
}

@Override
public boolean onOptionsItemSelected(MenuItem item) {
    // Handle action bar item clicks here. The action bar will
    // automatically handle clicks on the Home/Up button, so long
    // as you specify a parent activity in AndroidManifest.xml.
    int id = item.getItemId();
    if (id == R.id.action_settings) {
        return true;
    }
    return super.onOptionsItemSelected(item);
}

@SuppressWarnings("deprecation")
public void SaveButton_Click(View view)
{
    try{
           conn = new Mongo("localhost");
          }catch (Exception e){
           throw new RuntimeException(e);
          };
          DB db = conn.getDB("grade");
          DBCollection coll = db.getCollection("Student"); 
          BasicDBObject doc = new BasicDBObject();
          doc.put("name", R.id.nameEditText);
          doc.put("num",R.id.nameEditText);
          doc.put("age",R.id.ageEditText);
          doc.put("sexual",R.id.sexualEditText);
          coll.setWriteConcern(WriteConcern.SAFE); 

}

}

模拟器连接本地pc机不认localhost,应该是10.0.2.2
可以参见http://blog.csdn.net/lyq8479/article/details/6665104

把localhost改成了10.0.2.2还是不行,
发现了一个问题图片说明

mongo那里划了一条线,怎么了?

问题已解决
除了地址之外,还有以下其他几点:
mongo()构造器改为mongoclient()
还要在这点一开始没注意到!
