Hi Arunesh,

Firstly, thank you again for doing the java port.

I've one question regarding the features of the port:
Is there or do you plan to add a feature for iterating over the index? (Similar to find/findByTitle in C++ zimlib)
This would be required to add some auto complete feature to the phonegap app.

Best regards,
Christian

Yes, images are not compressed in ZIM files, as Emmanuel pointed out.

Also, I have tried decompressing a LZMA compressed file on an Android phone (HTC Wildfire to be precise), and the decompression speed is not a problem.

LZMA-Java is under frequent development by Lasse Collin, so we should make sure that the latest code is used.

Images should not be compressed in ZIM files for the obvious reasons
they mainly are already compressed. This is the case for all ZIM files I
made. As far as I know this is also the case for Mediawiki:Collection
build ZIM files.
