Question

Hi I want to send a fixed amount of data (say 5MB) from server to Android client over TCP using the Java programming language. The data doesn’t matter it will be dropped at the client I am only doing this to do performance measurements on the phone.

Can anyone recommend a good way of accomplishing this? How can I have the server continually sending a large amount of data? Without the intermittent behaviour of reading a line from a file, then sending those bytes… then reading another line and sending those ones.

Ideas? Cheers.

You don’t need to send a file, you could just send a block of data.

// server which sends 5 MB on connection.
ServerSocket ss = 
Socket s = ss.accept();
s.getOutputStream().write(new byte[5*1024*1024]);
s.close();
