将mssql连接到android应用程序

我试图将我的android应用程序连接到mssql数据库。但当我尝试连接时，我遇到了一个异常。我已经在调试模式下检查，并从Class.forName去异常捕获这里是我的代码。将mssql连接到android应用程序

protected void onStart() { 
    try 
    { 
     // Load the SQLServerDriver class, build the 
     // connection string, and get a connection 
     Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver"); 
     String connectionUrl = "jdbc:sqlserver://xxx\\xxxxx:1433;" + 
           "database=xxxx;" + 
           "user=xxxx;" + 
           "password=*****"; 
     Connection con = DriverManager.getConnection(connectionUrl); 
     System.out.println("Connected."); 

     // Create and execute an SQL statement that returns some data. 
     String SQL = "SELECT COUNT(*) FROM xxxxxx"; 
     Statement stmt = con.createStatement(); 
     ResultSet rs = stmt.executeQuery(SQL); 
     TextView tv=(TextView) findViewById(R.id.textView1); 
     tv.setText((CharSequence) rs); 


     // Iterate through the data in the result set and display it. 
     while (rs.next()) 
     { 
      System.out.println(rs.getString(1) + " " + rs.getString(2)); 
     } 


    } catch (Exception e) { 
     e.printStackTrace(); 
    } 
    super.onStart(); 
}
