Chat along with another data sending in socket programming android

I'm developing a project where client sends screenshots of its activity to server where the bitmap is converted to string.For me it works well.I would like to add a chat between client and server in this project.How can I achieve this?Any kind of help is accepted.

Searching the Server IP on Client instead of inputing

Server: PC
Client: Android
So my Client/Server app consists in opening webpages and executing a bot, everything is fine if I use only for a router, but I would like to be able to to connect in different places (different router/PC).
I was searching for "Wi-fi Search of IP" and got nothing.
Is it possible to give to the Server side a fix IP? like always 192.168.1.68?

You can use ServerSocket(int port, int backlog, InetAddress bindAddr)
Constructs a new ServerSocket instance bound to the given localAddress and port.

Value getting toasted but not getting in textview?

I am developing the android application in which sever sends the command to client and client side works on command and sends the result.
I am using handler in client side on every 15 sec to write the data on server side.
My problem is i am getting the output from client side and toasted correctly but the value is assigning to Textview first time which comes from client when the second time the value comes its getting toasted correctly but not assigning to Textview
Here my code Goes

I toasted my string in run method of connectthread class
like
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
And after that i am assigning the value to the textview
I am getting the correct value in toast.
i am getting the problem at server side near
if(count<5)
{
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
contact.setText(msgLog);
}
this code
In 'contact' textview i am setting the value
Thanks in advance

Since you are using msgLog in UIThread,
thus its value replace when this thread repeat run method.
try to append new value on msgLog not just replace it
msgLog="";
while (true) {
if (dataInputStream.available() > 0) {
String newMsg = dataInputStream.readUTF();
msgLog += newMsg;
ServerSocketNew.this.runOnUiThread(new Runnable() {
#Override
public void run() {
// infoIp.setText(msgLog);
// Toast.makeText(getApplicationContext(), "prev="+prev, Toast.LENGTH_LONG).show();
// Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
Log.e("Number",msgLog);
e2.setText(msgLog+"#"+msgLog);
if(count<5)
{
Toast.makeText(getApplicationContext(), "messagelog="+msgLog, Toast.LENGTH_LONG).show();
// Flags="False";
// contact.setText("");
// contact1.setText("");
//contact1.setText(msgLog2);
contact.setText(msgLog);
}
count=count+1;
}
});

I m not receiving real time stream because receivePacket is the most 1024 bytes

i want to do real time stream from my pc to android device with WIFI. Server code is written by Java. My codes is running true. when I clicked the button in android, in server, sendPacket is actived and it sends packet. I send 65000 bytes(sendPacket) from server, but client receive is 1024 bytes(receivePacket). that' s problem. If sendPacket is smaller, view is very bad.Thank you for your helps...

i don't know why my code isn't working, my progress bar won't update and file not send.
Anyone can help me? thx before

You've got a lot of code, but as long as I know, the receiver should use an AsyncTask, that's how I do it and it works for me. Instead of a thread use an Asynctask and the OnProgressUpdate method of the AsyncTask to update the ProgressDialog in the main thread.
For example:
public class getFile extends AsyncTask<Void, String, Void>
{
ProgressDialog pB;
String hostAddress=null;
InetSocketAddress socketAddress;
Socket socket=null;
ServerSocket serverSocket=null;
int port=3001;
int SOCKET_TIMEOUT = 3000;
public getFile(String _hostAddress, Context context)
{
this.pB = new ProgressDialog(context);
this.pB.setTitle(context.getText(R.string.sYourMessageText);
this.pB.setMessage(null);
this.pB.setProgressNumberFormat(null);
this.pB.setProgressPercentFormat(null);
this.pB.setCancelable(false);
Drawable d = getResources().getDrawable(R.drawable.x_greenprogress);
pB.setProgressDrawable(d);
pB.setProgressStyle(ProgressDialog.STYLE_HORIZONTAL);
hostAddress=_hostAddress;
}
#Override
protected void onPreExecute()
{
this.pB.show();
}
#Override
protected Void doInBackground(Void... params)
{
try {
//sent ip
socketAddress = new InetSocketAddress(this.hostAddress, port);
socket = new Socket();
socket.bind(null);
socket.connect(socketAddress, SOCKET_TIMEOUT);
PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())), true);
out.println(messsage);
out.flush();
out.close();
socket.close();
socket = null;
//receive file
socket = new Socket();
serverSocket = new ServerSocket(portal);
socket = serverSocket.accept();
final String name;
final String ext;
String[] tokens = filename.split("\\.(?=[^\\.]+$)");
name = tokens[0];
ext = tokens[1];
final File f = new File(Environment.getExternalStorageDirectory() + "/"
+ getPackageName() + "/" + name + System.currentTimeMillis()
+ "." + ext);
File dirs = new File(f.getParent());
if (!dirs.exists())
dirs.mkdirs();
f.createNewFile();
InputStream is = socket.getInputStream();
FileOutputStream fos = new FileOutputStream(f);
BufferedOutputStream bos = new BufferedOutputStream(fos);
byte buf[] = new byte[1024];
while ((len = is.read(buf)) != -1)
{
bos.write(buf, 0, len);
bos.flush();
fileSize+=len;
// to update the progress bar just call:
this.publishProgress("" + (int) ((fileSize * 100) / filelength));
}
is.close();
fos.close();
bos.close();
socket.close();
serverSocket.close();
}
#Override
protected void onProgressUpdate(String... progress)
{
this.pB.setProgress(Integer.parseInt(progress[0]));
}
#Override
protected void onPostExecute(Void result)
{
if (this.pB.isShowing())
this.pB.dismiss();
}
}
EDIT:
By the way, why do you connect to the server, send an IP close the connection and wait for the server to connect? Why don't use the first socket to do the file transfer? The connection has already been established.
