Could not cache the input file.

Error message

Could not cache the input file.

What it means

ApkFile could not materialize a readable cache copy or file descriptor of the input package: getFdFromUri opened the URI but no local, cacheable file could be derived from the descriptor, so later zip operations have nothing to work with. Faulty input: a content URI whose provider cannot back a seekable, cacheable file.

Solutions

1. Copy the URI contents into the app's cache manually and open ApkFile from the local file instead
2. Check storage permission and free space in the cache directory
3. Ask the user to re-share the file via a local path or the FmProvider authority
