How to pass JPEG from JAVA to C in Android

Question

I need send JPEG data to C executable process and return some data from that C process back to JAVA part within Android on non root phone. What could be the best solution ? I heard about pipes. I use IPC with TCP and sockets now, but sockets randomly stuck. Part of my IPC is in JNI too, but I would like don't use JNI again. My C process is started from Java by command Runtime.getRuntime().exec(command)

I think that this code from Peter Knego could be useful, but it is not complete and he didn't provide C part.

String command = "ls";
Process child = Runtime.getRuntime().exec(command);

// Get pipes from process
InputStream in = child.getInputStream();
OutputStream out = child.getOutputStream();
InputStream error = child.getErrorStream();
