I was updating my XML files produced from the B4XLibs in B4A standard libraries using b4xlib2XML
All worked except KeyValueStore.b4xlib which produces an error in the Archiver at line 38 in the XMLGenerator module.
It looks like either the Archiver can't cope with however that b4xlib was compressed or whatever compressed it did it wrong, but in a way that other utilities, like 7-Zip don't mind.
[Tool] b4xlib - XML generation
b4xlibs do not require an XML file. The IDE parses the packed code modules. With this tool you can generate the XML from the packed source code. It is useful for documentation purposes as there are tools that expect this XML. For example...
www.b4x.com
B4X:
a.UnZip("", b4xlib, TempFolder, "") ' Error here at line 38
java.io.IOException: java.util.zip.ZipException: invalid entry size (expected 0 but got 163 bytes)
