App Update (Android)

 

Preface: Currently, General Android software is constantly updated. when you open an app, if there is a new version, it will prompt you to have a new version to be updated. This function is implemented in this project. In addition, there are two ways to force update and update prompt. When there is an update, a prompt box will pop up. Click Download to create a progress bar for download in the notification, and click Cancel, cancel the update.
