Invalid package extension.

Error message

Invalid package extension.

What it means

Generic validation guard in the private ApkFile constructor: the URI's resolved MIME type is not in SUPPORTED_MIMES, so the source cannot be interpreted as any supported package format (apk, xapk, apks, apkm). The faulty input is apkUri/mimeType pointing at a non-package file or an unresolvable content URI.

Solutions

1. Pass a URI whose MIME type is one of App Manager's supported package types (application/vnd.android.package-archive, vnd.apkm, xapk, apks)
2. Verify the file is a real APK/bundle rather than a corrupted download before opening it
3. If the type is legitimately missing from SUPPORTED_MIMES, extend the supported set instead of forcing the call
