Hi!
I have released an open source library for decompress GZIP files.
Its a class with a static method which receive an array with the gzip data and returns an array with the uncompressed data.
For now its not a class derived of InputStream because so its faster and smaller, once ofuscated (with proguard) and jaring is less than 2250 bytes, although maybe i will do also an InputStream version soon.
The URL for download is http://www.java4ever.com/index.php?section=j2me&project=apime&menu=download&lang=
Thanks.
