Hi Christian, You can look at getDirectoryInfo(String articleName, char namespace) in ZimReader.java This'll return null if there is the article doesn't exist, else the DirectoryEntry object. (Is this what you were looking for?)
Actually I plan on adding more features if required. Do you think there are any missing, when compared to zimlib? If yes, could you list them?
Have you tested zimreader-java on an Android phone? How is it's performance?

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.

The JAVA liblzma performance is pretty bad: To increase efficiency of compression in the zim-format articles (and also all other data like images) are stored in clusters. Cluster size is
apparently about
1 MB. This implies that loading an article which is stored at the end of a cluster involves decompressing the
complete
cluster.
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.
