Amazon announced support for Android App Bundles in its Appstore. Amazon will make it optional for developers to use App Bundles. The Amazon Appstore will be the default source for Android apps on Windows 11. In a surprising move on Friday, Amazon announced that it is supporting Android App Bundles for the Amazon Appstore. App Bundles were recently announced by Google as its replacement for APKs. The new format touts smaller file sizes for faster downloads, dynamic asset compression, and more, making it an ideal solution for many of the best cheap Android phones. And while there are some benefits to the move, it has caused some worry over support for third-party app stores that rely on APKs since Google is making the move to App Bundles mandatory for new apps later this year.
