Hi, Kostya I can't use second solutions because they are for API level8 and I am developing this for APilevel4(1.6), But after changing byte array size to 1023 it works perfectly fine, Thanks again Kostya I am working on this from last 8 days and today I got the solution.
But still I don't know how it works with 1023 and not with 1024?
