Games using Play Asset Delivery can use texture compression format targeting, so your users only get the assets suitable for their device, with no wasted space or bandwidth. Play Asset Delivery: Reduces user waiting time by dynamically delivering large assets while cutting delivery costs.

Play Feature Delivery: Used by more than 10% of the top apps using app bundles, Play Feature Delivery gives you the ability to customize what feature modules are delivered to which device and when, with install-time, conditional, and on-demand delivery modes.

Play App Signing: Play App Signing, which is required for app bundles, protects your app signing key from loss by using Google’s secure infrastructure and offers the option of upgrading to a new, cryptographically stronger app signing key.

This makes your app smaller (on average, 15% smaller than a universal APK) and faster to download, which can lead to more installs and fewer uninstalls.

Android App Bundle: Google Play uses the app bundle to generate and optimize APKs for distribution for different device configurations and languages.

If you haven’t made the switch to app bundles yet, here are some of the benefits you’re missing: This will replace the APK as the standard publishing format. To bring these benefits to more users and focus on modern Android distribution that benefits all developers, Google Play will start requiring new apps to be published with the Android App Bundle starting August 2021. There are now over 1 million apps using app bundles in production, including the majority of the top 1,000 apps and games on Google Play such as Adobe, Duolingo, Gameloft, Netflix, redBus, Riafy, and Twitter.

Since we launched the Android App Bundle in May 2018, we’ve seen our developer community embrace this new standard to benefit from streamlined releases and advanced distribution features.
