android本地sql连接无效凭据

Question

public class ConnectionClass {
    String ip = "192.168.1.99";
    String classs = "net.sourceforge.jtds.jdbc.Driver";
    String db = "androidtest";
    String un = "mytestuser";
    String password = "db123456";

    @SuppressLint("NewApi")
    public Connection CONN() {
        StrictMode.ThreadPolicy policy = new StrictMode.ThreadPolicy.Builder()
                .permitAll().build();
        StrictMode.setThreadPolicy(policy);
        Connection conn = null;
        String ConnURL = null;
        try {

            Class.forName(classs);
            ConnURL = "jdbc:jtds:sqlserver://" + ip + ";"
                    + "databaseName=" + db + ";user=" + un + ";password="
                    + password + ";";
            conn = DriverManager.getConnection(ConnURL);
        } catch (SQLException se) {
            Log.e("ERRO", se.getMessage());
        } catch (ClassNotFoundException e) {
            Log.e("ERRO", e.getMessage());
        } catch (Exception e) {
            Log.e("ERRO", e.getMessage());
        }
        return conn;
    }
}

我连接SQL Management Studio这个测试用户，但Android模拟器提供＆＃34; Invalid Credentials＆＃34;错误。如何解决这个问题？

编辑：连接成功。
