进行了Androidstdio的安装与配置，这是连接数据库的代码

public class JDBCUtils {

    private static String driver = "com.mysql.jdbc.Driver";// MySql驱动
    private static String dbName = "face";// 数据库名称
    private static String user = "root";// 用户名
    private static String password = "a123456";// 密码

    public static Connection getConn(){
        Connection connection = null;
        try{
            Class.forName(driver);// 动态加载类
            String ip = "192.168.32.174";// 写成本机地址，不能写成localhost，同时手机和电脑连接的网络必须是同一个

            // 尝试建立到给定数据库URL的连接
            connection = DriverManager.getConnection("jdbc:mysql://" + ip + ":3306/" + dbName + "?characterEncoding=UTF-8",
                    user, password);
        }catch (Exception e){
            e.printStackTrace();
        }
        return connection;
    }
}
