MuntashirAkon/AppManager · error · ApkFile.ApkFileException

Package name not found.

Error message

Package name not found.

What it means

The bundle's base APK entry was found, but the package name could not be read from it (missing or unparseable manifest/metadata in the split), so ApkFile cannot identify what it is opening and aborts. Faulty input: a split archive whose base APK lacks a resolvable package name.

Solutions

1. Use an intact base APK whose AndroidManifest can be parsed; rebuild the bundle if it was modified
2. Verify the archive was not edited or re-zipped in a way that dropped manifest entries
3. Reject the file at import time with a clear user-facing message
