Android realizes the encapsulation of login and registration function

We all know that Android applications basically use the login and registration function, so it is necessary to encapsulate a good login and registration module. Here I would like to introduce the login and registration function used in my first project. It has been encapsulated. I hope it can be helpful to you. If there are any errors or improvements, I hope you can point out.

We all know that there are the following steps to realize the login and registration functions:

The general process is as follows

For the operation that needs to obtain the user login status, first judge whether the user has logged in.

If the user has logged in, continue with the following operations. Otherwise, jump to the login page to log in.

If you already have an account, you can log in directly, or you can directly select a third-party platform to authorize login.

If you do not have an account, you need to register the account first, and then log in after successful registration; You can also log in through a third-party platform without registering an account.

If you have an account but forget the password, you can reset the password, otherwise you can log in directly.

Well, the common functions of a login registration series are the above five points, and the general process has been known. Next, let's implement them one by one.

Implementation of registration function

When registering, I usually register by mobile phone or email. Here I choose to register by mobile phone number; The verification code is usually received during registration, which is realized through the sms sdk of the third-party mob platform, and the third-party account authorization is also realized by using mob's sharesdk. After registration, the client submits the registration information to the server for registration in the post request mode of HTTP.
