That .apkm file will not install from your file manager
Downloaded a beta update today. Tapped the file in the file manager. Nothing happened. No error, no install screen. Nothing. The file was fine. The format was the problem. An .apkm is not an APK It is a zip. Inside is not one app but a set of them: a base.apk , plus config splits. One split per CPU architecture, one per screen density, one per language, and sometimes a pile of feature modules on…
A user encountered issues while attempting to install a beta update from an .apkm file using their file manager. The file manager did not display an error or an install screen after attempting to open the file. The user discovered that .apkm files are not APKs but rather zipped archives containing multiple components. These components include base.apk, configuration splits, one for each CPU architecture, screen density, language, and additional feature modules.
To successfully install the update, the user needed to use adb and unzip the .apkm file first. They found that one bundle was 201 MB with over 30 splits inside, while another was 340 MB with 126 files, 85 of which were feature splits. The user needed only four files from the first bundle and 72 from the second.
Before installing, the user checked the signature of the update to ensure it matched the installed app. They ran two checks: comparing the versionCode and verifying the signing certificate. Both checks confirmed that the update was valid and safe to install. The user then installed only the necessary splits based on their phone's architecture, density, and language preferences using adb install-multiple command. After installation, they verified the version and confirmed that the app was running the new version.
