Web storage is a data persistence store in the form of Key-value. Web storage are designed to overcome some of the limitations that are caused by cookies. When data needs to be tightly controlled on the client, it is not necessary to continuously send the data back to the server. There are two goals for WEB storage: To provide a path for storing session data, and

The Android system provides a system-level Configuration Storage scheme for applications, which is implemented by the Sharedpreferences interface, where all the information stored in the interface is saved in the form of a name-value pair, but its data types are limited to basic data types such as strings, shapes, booleans, and so on. These configurations are eventually saved in an XML file, and each time the app is opened, the saved information is lo
