I looked at DataOutputStream and the only difference I saw was that the doc said that it sends the data in big-endian format. I'm not sure if OutputStream is big-endian or little-endian, I think it's little-endian. DataOutputStream is inherited from OutputStream so they should have the same functionality. Anyway, so your problem is that you're not seeing anything on the other end(Server end). I would use some kind of network analyzer on the server end to see what's coming in. Another thing I'm not quite sure about is that you use flush. In my code, I don't use flush. I just call myoutputstream.write(aByteArray);
I see that this line: dataout.write(bdata,0,bdata.length); has length 0 because bdata is not set to any data. The offset which you have as 0 is fine but unless you are setting bdata to some value or values, it won't write anything because the length is zero. Otherwise it should write something to that socket. If that is not all of your code maybe you can post more of it but if thats all of it, that is what your issue is(bdata.length = 0).
