Android data compression (except java.util.zip?)

I have a lot of data (text format) to send from the device. That obviously means I have to squeeze it. But my question is, are there any ways to do this other than using a zip algorithm ( like this ). The reason I ask this question is here for a text file, i.e. 7-zip twice (!) Better than zip. This is a significant gain. And perhaps there are even better algorithms.

So, are there any efficient ways to compress data (better than zip) for Android?

You will need to compile another library into your code, since I doubt that compression algorithms other than zlib are available as part of the standard Android libraries.

The 7-zip algorithm you are referring to is actually called LZMA, which you can get in the form of a library in the LZMA SDK . The source code is available in both Java and C. If you can associate C code with your application, this would be preferable for speed.
