Dunction seems well-structured, but there could be a few potential issues causing it not to work as expected. I'll provide a few suggestions and possible fixes to help you troubleshoot the problem:
Potential Issues and Fixes
File Path Issues:
Ensure that the file path passed to listZipContents is correct and accessible from your application. Sometimes, file paths may differ between development and production environments. You can add logging to verify the file path.
Permissions:
If the app is running on Android, make sure that the app has the necessary permissions to read from the storage. You might need to check and request storage permissions at runtime.
ZipFile Close:
Although you are closing the ZipFile after reading, if there's an issue while iterating over entries, the file may not close properly. You can use a try-with-resources statement to ensure the ZipFile is always closed, even if an exception occurs.
React Native Promise
Ensure that the React Native Promise mechanism is being handled correctly. Make sure you are not trying to resolve or reject the promise multiple times.
File Not Found Exception:
If the file is missing or the path is incorrect, make sure to handle this gracefully.
