DataFormatException: invalid stored block lengths

[farrukhnajmi]

Thanks for a great library.

Using latest version 2.2.4 of zip4j, I am using the following code to extract a zip file:

        ZipFile zipFile = new ZipFile(assetFile);
        zipFile.extractAll(assetExtractionFolder.getAbsolutePath());

and getting the following exception. Note zip file opens fine with zip command in my Ubuntu 18.04 laptop.

Thanks for the zip file. It will greatly help me investigate the issue. I will update the thread once I find something.

[srikanth-lingala]

Issue fixed in v2.2.6 release just now. It might take a few mins to a couple of hours until the version is synced to maven central.

Srikanth you are truly awesome! I am amazed by the responsiveness of this project. Thank you.

[farrukhnajmi]

Confirming the fix! Thanks again @srikanth-lingala for the awesome help.

I have got this issue on v2.2.7 when I gave the wrong password to extract the zip file.
zip file password is 123, I gave 12jdfkl.

doAsync {
val protectedZip = ZipFile(zipFilePath, zipPassword.toCharArray())
protectedZip.extractAll(extractAt)
mFileList = StorageUtils.instance.getWeBoxFilesAtStorage(extractAt)
uiThread {
setAdapter()
dismissProgressDialog()
}
}
