The nature of apps on mobile devices is that you can't use them while they're updating. Google has added widely requested features in the latest In-app Updates API.
But Google noted that the app has grown to 30 million monthly users, some of which were using powerful phones with plenty of storage. But this is about to change, now that Google is introducing a new API for Android. The Android Developers blog says that the "update flow" can be customized to feel like part of the app (see GIF at the top of this article).
The tool, very appropriately dubbed the Google Play in-app update API, gives developers the ability to display dialog boxes in unupdated Android games or apps that either encourage players to update their copy to the latest version and allow them to do so while the app is still running. The first is a full-screen experience, which blocks use of the app until the update downloads and installs.
Google also rolled out Instant discovery that allows to easily adopt the new kind of apps.
Android's announcement of its Foldables technology was also a summit highlight, with the company highlighting its support for the forthcoming Samsung device that was previewed this week by Samsung Senior Vice President Justin Denison at the 2018 Samsung Developer Conference. Google hasn't announced an official date that it will get wide release but said the API will be available to all developers soon.
