The flexible option gives devs the ability to nudge app users towards updating to the latest version of an app through more subtle banners in the app.
According to the example provided by Google, the first one - called "immediate in-app update" - will also have an on-screen pop up, letting you know that an update is available. Google has introduced new tools and features at Android Developer Summit. Another neat reveal coming out of the Android Dev Summit, however, is a feature that will allow users to continue using Android apps while they're being updated. The former doesn't boot you out per se, but the update window takes up the entire screen, so you're essentially prevented from using the app while the update occurs. The prompt comes when the user starts an app, they must update it before using it. There is no specific date mentioned by Google as to when we will see the API in use on Android apps.
"Last December, Google launched Files Go: an app to free up space on mobile phones, find files faster and share them with others easily and quickly-even without an internet connection", states Google's announcement."Files Go was built to solve file and storage management problems for the next generation of smartphone users in countries such as India, Brazil and Nigeria".
Google's new contract for Android vendors that want its core apps aims to bring the industry in line with Samsung's security patching model.
