Bug: crash when trying to parse VectorDrawable binary XML file

I try to parse some XML files, and check if an XML file is indeed a VectorDrawable one:

            try {
                val doc = CompressedXmlParser().parseDOM(ByteArrayInputStream(data))
                Log.d("AppLog", "got docs")
            } catch (e: Exception) {
                e.printStackTrace()
                Log.d("AppLog", "")
            }

For some reason, when I try it, I get java.lang.NegativeArraySizeException: -126 .

How come?

Attached the file.

ic_launcher_foreground.zip

Also attached POC project that I used for this:

apkInfoUsingSaf.zip

CompressedXmlParser.getStringFromStringTable method throwing a ArrayIndexOutOfBoundsException

When the parser seems to encounter an element with an attribute that has a long value, the getStringFromStringTable method throws an ArrayIndexOutOfBoundsException.

Here exactly :

The file causing this behavior looks like this :

Only supported on Android?

I tried using this on a non-Android project and Gradle can't find some libs in the Google repo. This is fine, but it might be good to add to the readme :D

$ gradle build                                                                                 1 ↵

[Q] I/O

hi,

thanks for sharing your code!

by any chance... do you happen to be aware of a library that both reads and writes binary xml?

thank you!
