android下可以连接远程数据的，不过你远程的数据库服务的要开启远程，具体设置http://www.ways2u.com/knowledge/?post=142

Java利用JDBC访问数据库的编程步骤
http://www.ways2u.com/?post=76

android 链接mysql数据库实例：
package com.hl;

import java.sql.DriverManager;
import java.sql.ResultSet;

import com.mysql.jdbc.Connection;
import com.mysql.jdbc.Statement;

import android.app.Activity;
import android.os.Bundle;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class AndroidMsql extends Activity {
    
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        Button btn=(Button)findViewById(R.id.btn);
        btn.setOnClickListener(new OnClickListener() {
   
   @Override
   public void onClick(View v) {
     sqlCon();    
   }
  });
       
    }
    
    private void mSetText(String str){
      TextView txt=(TextView)findViewById(R.id.txt);
      txt.setText(str);
    }
    
    private void sqlCon(){
     try {
         Class.forName("com.mysql.jdbc.Driver"); 
  } catch (Exception e) {
   e.printStackTrace();
  }
  try {
            String url ="jdbc:mysql://192.168.142.128:3306/mysql?user=zzfeihua&password=12345&useUnicode=true&characterEncoding=UTF-8";//链接数据库语句
            Connection conn= (Connection) DriverManager.getConnection(url); //链接数据库
            Statement stmt=(Statement) conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
            String sql="select * from user";//查询user表语句
            ResultSet rs=stmt.executeQuery(sql);//执行查询
            StringBuilder str=new StringBuilder();
            while(rs.next()){
             str.append(rs.getString(1)+"\n"); 
            }
            mSetText(str.toString());
        
            rs.close();    
            stmt.close();
            conn.close();
            
  } catch (Exception e) {
   e.printStackTrace();
  }

 }

}

不过eclipse老是提示：
warning: Ignoring InnerClasses attribute for an anonymous inner class that doesn‘t come with an associated EnclosingMethod attribute. (This class was probably produced by a broken compiler.)
不知道谁有解决的办法呢？？
