To tackle this issue, we instruct android compiler to create an AAB (app bundle) file instead of an APK. A smart watch app will only need low resolution images.

Binaries of architectures such as x86, x86_64 should not be included. For instance, a phone with an ARM CPU should download an APK that only ships ARM binaries. Ideally, we want a user to download an APK with only relevant files. App bundles are invented to solve this problem. This whole portability approach creates bloated APKs, sometimes consists of more than ~75% percent of unused data. Moreover, app resources such as images and videos must be shipped multiple times to support various screen sizes. To be able for an APK to support all Android devices, it has to ship necessary binaries for all kinds of CPU architectures. APK files are ZIPs of compiled java code, XML layouts, native library binaries and other resources.

In the traditional workflow, an Android app is compiled into an APK file.

For those who haven’t got the chance to play with app bundles yet, we are going to take a closer look. Google recently announced that “From August 2021, new apps will be required to publish with the Android App Bundle (AAB) on Google Play”. aab files to Android users?Ī: TestFairy allows.
