Android App Bundle
Android App Bundle is a publishing format for Android apps that allows developers to build and deliver optimized APKs for different device configurations. It enables Google Play to generate and serve split APKs (APK splits) tailored to each user's device, reducing app size by excluding unused resources and code. This format replaces the traditional monolithic APK for app distribution on Google Play.
Developers should use Android App Bundle when publishing apps on Google Play to reduce app size, improve download speeds, and enhance user experience, especially for users with limited storage or data plans. It is essential for modern Android development as it supports dynamic delivery features like on-demand modules and instant apps, and it is required for publishing new apps on Google Play since August 2021.
