When your users keep your app up to date on their devices, they can try new features, as well as benefit from performance improvements and bug fixes. Although some users enable background updates when their device is connected to an unmetered connection, other users might need to be reminded to install updates. In-app updates is a Play Core library feature that prompts active users to update your app.
The in-app updates feature is supported on devices running Android 5.0 (API level 21) or higher, and requires your app to use Play Core library version 1.5.0 or higher. Additionally, in-app updates are only supported for Android mobile devices, Android tablets, and Chrome OS devices.
Your app can use the Play Core library to support the following UX flows for in-app updates:
Flexible updates provide background download and installation with graceful state monitoring. This UX flow is appropriate when it's acceptable for the user to use the app while downloading the update. For example, you might want to encourage users to try a new feature that's not critical to the core functionality of your app.
Immediate updates are fullscreen UX flows that require the user to update and restart the app in order to continue using it. This UX flow is best for cases where an update is critical to the core functionality of your app. After a user accepts an immediate update, Google Play handles the update installation and app restart.
