During normal development, we may sometimes need some global data to make all the activities and views in the application accessible. In this case, you may first want to define a class and then create many static members. However, Android has

"Android threading Mechanism"For performance reasons,Android UI operations are not thread-safe, which means that if there are multiple threads concurrently manipulating the UI component, it can cause thread safety issues. To solve this problem ,

The example in this article describes how the Android operation SQLite the database under the Assets folder. Share to everyone for your reference. Specifically as follows: Because this project needs to bring data, so put the data into a SQLite

Introduction:There is always a need for some information in many places in your application. It can be a session, the result of an expensive calculation, etc., it is usually tempting to let you avoid the overhead of passing objects between activity

In an app there's always some data that needs to be used in multiple places. The data can be a session token, a time-consuming calculation, and so on. Typically, to avoid the overhead of passing objects between the activity, the data is generally

Each time the program runs, it creates an object of the application class and only one. The application disappears at the end of the app. So you can use application to do some data processing and storage. Exchange data between multiple activity or
