Question

I'm trying to establish a connection beetwen my client(.java) and my server(.c) but everytime i try i got this error:

Error in initializing local socket: java.io.IOException: Connection refused

I know the problem it's my client:

private LocalSocket localReceiver;
try {

        localReceiver = new LocalSocket();
        localReceiver.connect(new LocalSocketAddress("serverSocket"));


        Log.d(LOG_TAG, "Done: init()");
    }catch(IOException e) {
        Log.e(LOG_TAG, "Error in initializing local socket: " + e);
    }
