(1) User registration module: realizes user registration. Users need to enter basic personal information when registering;
(2) Login module: realizes registered users logging into the system;
(3) realizes the verification code generation interface;
(4) click to obtain verification When coding, use the service to implement the 60-second countdown function;
(5) The countdown time is displayed on the interface;
(6) Write multiple interfaces to realize jumps between interfaces, including one-way and two-way adjustments

The principle is based on the development of Android applications. It uses the components and functions provided by the Android framework to implement user registration, login and mobile phone verification code login functions.

Underlying architecture flow chart:

用户注册模块：
1. 用户打开注册界面，输入基本的个人信息。
2. 用户点击注册按钮，触发注册逻辑处理。
3. 注册逻辑处理包括验证用户输入的信息是否有效，将用户信息存储到数据库或服务器等持久化存储中。
4. 注册成功后，跳转到登录界面。

登录模块：
1. 用户打开登录界面，输入已注册的用户名和密码。
2. 用户点击登录按钮，触发登录逻辑处理。
