Expansion Files (OBB): Smaller Updates For Users14 June 2021
Based on Bazaar regulations, the size of the uploaded APK must not be more than 150MB. For most apps, this amount provides enough space for application codes and assets. However, some apps need more space for high-quality graphic files, media files, and other large assets.
Before, developers had to upload all of their application assets as one APK file; therefore, while updating the app, the large size of the downloading process harmed users’ experience. So now Bazaar allows you to upload two large expansion files for each APK in the panel.
One of the significant benefits of using expansion files is the ability to update your application without re-downloading all of its original assets so that users will receive updates in a smaller size.For more information, see Expansion Files.
