    Searching a compressions algorithmn

    Which is Apache Software Licence 2.0 compartible. Fast in decompression and need max 8mb better less, optimal <4mb for decompression. Decompressor should be smaller than 500kb, optimal <200kb. Compression timings and memory consumption can be bad & big..


    Files to compress are: java byte code, dex, text, grafics, xml, binaries


    thx in advance

    CMs are stronger but slower (especially at decoding) and need more memory (at least 32M).
    Also CMs are mostly stronger on texts and such, while with binaries its not so certain.

    Although I guess you can check ppmd and ppms:
