For guidelines on managing multiple application versions and application updates, see Application Versions.
When you update an app, you can choose to send a push notification to the devices of users who have installed the app and have the new version assigned to them. On iOS devices, the push notification flags the App Catalog icon on the user's Home screen with a badge that identifies the number of updates available. On Android devices, the user receives a notification in the Notifications area and can tap it to open the App Catalog.
Users receive push notifications only if the user is running an App Catalog for which the Push Notification feature is enabled. For information on enabling Push Notification, see Push Notification for an App Catalog.
Once in the App Catalog—regardless of whether a push notification is sent—users can install any updates that are available to them. In the App Catalog, Apperian flags updates a couple ways:
Update button: When a native app is installed on the device and an update for that app is available, the Open button changes to Update on the All page and any other page listing the app in the App Catalog. The user can tap Update to install the update directly from the app listing.
With iOS apps, the Open button display only if the URL scheme is defined within the app's binary, and/or the app was signed with Apperian. When the user installs an app that does not meet either criterion, the App Catalog displays an Installed button instead of the Open button. Whether the button is Open or Installed, when there is an update of the app available to the user, the button changes to Update.
When you update an iOS or Android app, you can make the update mandatory to specify that users are required to update to the new version by a particular date. When an update is mandatory, users are prompted to install it when they log in to the App Catalog, and they cannot continue using the App Catalog until all mandatory updates are installed.
If you do not require the user to update by a specified date, then the update is optional—that is, the user chooses when and if to install the update.
The Self Updating App policy makes it easier for users to stay current with app versions. When a user launches an app with this policy applied, Apperian checks if there is a new version, and if there is, prompts the user to install it. The Self Updating App policy is different from the push notifications and Updates page described above in that rather than relying on the user to initiate installation of an update through the App Catalog, Apperian instead prompts the user to update while the user is launching the app.
When an update is mandatory, the user must either install the update or exit the app. When an update is optional, or when the date for a mandatory update has not yet been reached, the user can choose whether to install the update. If the user does not install the update, the user can continue to use the currently installed version. For more information on this policy, see Self Updating App.
