Updating an Application

For developers, to update an application, you need to first update the versionCode field in the app.json5 file, package the application using DevEco Studio, and release the application in the AppGallery. For users, the application may be updated in the following approaches:

On the AppGallery: The application market notifies the user of an available update, and the user can install the update by following the onscreen instructions.
In the application: When the application for which an update is available starts up, the AppGallery notifies the user of the update, and the user can install the update by following the onscreen instructions.
