Existing APK-based apps will still be supported and developers will be able to keep issuing updates. New apps submitted to the Play Store will need to be issued as an app bundle. Google will gradually phase out support for APKs from August 2021.
According to Google, all of this typically results in a 15% reduction in download size, compared to the same app distributed as an APK. The difference is the APKs are generated dynamically, in the cloud.Īpp Bundles also benefit from simpler add-on module loading and enhanced support for large assets such as game content. Crucially, devices still receive APKs – users won’t ever directly interact with an App Bundle. It’ll produce the right bundle on-demand for each user, so an American user with a 10-inch Intel device will get a different download to a German individual with a 5-inch ARM phone. The Play Store then sends only the relevant bits to each device which requests an install. By design, they “bundle” several different versions of an app into one logical package. If a developer wants to offer more streamlined builds, they need to manually compile and sign multiple different APKs.Īpp Bundles take a different approach.
Yet with APK, you’ll normally get every variation, causing larger downloads and increased storage use. If you install an app on your phone, you don’t really need to download the high-res tablet variants of its graphics.
