> Key: COMPRESS-508
> URL: https://issues.apache.org/jira/browse/COMPRESS-508
> Project: Commons Compress
> Issue Type: Improvement
> Components: Build
> Affects Versions: 1.20
> Environment: Android 9 and Android 10, on both emulator and real device .
> Reporter: AD_LB
> Priority: Major
> Attachments: 2020-03-31_20-53-36.png, 2020-04-01_18-28-19.mp4, ZipTest.zip, ZipTest2.zip, ZipTest3.zip, test.zip

> I'm trying to use ZipArchiveInputStream to iterate over the items of a zip file (which may or may not be a real file on the file-system, which is why I use a stream), optionally creating a stream from specific entries.
> One of the operations I need is to get the size of the files within.
> For some reason, it fails to do so. Not only that, but it throws an exception when I'm done with it:
> {code:java}
> Error:org.apache.commons.compress.archivers.zip.UnsupportedZipFeatureException: Unsupported feature data descriptor used in entry ...
> {code}
> I've attached here 3 files:sample project, the problematic zip file (remember that you need to put it in the correct path and grant storage permission), and a screenshot of the issue.
> Note that if I open the file using a third party PC app (such as [7-zip|https://www.7-zip.org/] ), it works fine, including showing the file size inside.
> Files:
> !2020-03-31_20-53-36.png![^test.zip]
> [^ZipTest.zip]
> Here's the relevant code (kotlin) :
>
> {code:java}
> thread {
> try {
> val file = File("/storage/emulated/0/test.zip")
> ZipArchiveInputStream(FileInputStream(file)).use {
> while (true) {
> val entry = it.nextEntry ?: break
> Log.d("AppLog", "entry:${entry.name} ${entry.size} ")
> }
> }
> Log.d("AppLog", "got archive ")
> } catch (e: Exception) {
> Log.d("AppLog", "Error:$e")
> e.printStackTrace()
> }
> }
> {code}
