Friends I Am trying to connect server on pc and client on android device..
Warning: I am not your friend.
My server is working fine...
but my client is not working ...
Here is my sever and client code...
Server Code...
public class Server_tcp {
Please follow the Java naming conventions.
void run(){
Why is this method not public?
{
try {
System.out.println(Hi Im In 1st Try);
try {
System.out.println(Hi Im In 2nd try );
Boolean end = false;
Why did you declare this 'Boolean' and not 'boolean'?
ServerSocket ss = new ServerSocket();
System.out.println(socket created);
while(!end){
//Server is waiting for client here, if needed
Socket s = ss.accept();
System.out.println(socket accepted);
Calls to 'System.out.println()' are the worst of the available logging
options.
BufferedReader input = new BufferedReader(new
InputStreamReader(s.getInputStream()));
PrintWriter output = new
PrintWriter(s.getOutputStream(),true); //Autoflush
String st = input.readLine();
System.out.println(Tcp Example + From
client: +st);
output.println(I got the Message:));
output.flush();
Why do you flush an auto-flushed stream?
s.close();
if (st==null){ end = true; }
}
ss.close();
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
Handle errors, don't ignore them.
}
} catch (IOException exp) {
// TODO Auto-generated catch block
exp.printStackTrace();
}
}
}
public static void main(String args[])
{
Server_tcp server = new Server_tcp();
while(true){
server.run();
So you restart the server every time you choose to close it. Hmm.
}
}
}
Client Code
public class ClientTCPActivity extends Activity {
/** Called when the activity is first created. */
private EditText et;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
System.out.println(Before try net);
Run();
Please follow the Java naming conventions.
System.out.println(after try net);
}
public void Run() {
System.out.println(inside try net);
try {
System.out.println(inside try);
Socket s = new Socket(192.168.1.27,);
//outgoing stream redirect to socket
// OutputStream out = (OutputStream) et.getContentDescription();
PrintWriter output = new PrintWriter(s.getOutputStream(),true);
output.println(Hello Android!);
BufferedReader input = new BufferedReader(new
InputStreamReader(s.getInputStream()));
//read line(s)
String st = input.readLine();
System.out.println(st);
//Close connection
s.close();
System.out.println( try );
} catch (UnknownHostException e) {
// TODO Auto-generated catch block
e.printStackTrace();
} catch (IOException e) {
// TODO Auto-generated catch block
e.printStackTrace();
}
}
}
My Client is not working properly my friends
What does that mean?
In other words, what did you expect, and what happened instead?
Copy and paste messages; do not paraphrase them.
Can Any One help me ???
You only need one question mark at the end of an interrogative sentence.
And no, not without sufficient information.

Re: [android-developers] Re: hi friends
I believe this is the relevant code where the real toast delay is set:
private void scheduleTimeoutLocked(ToastRecord r, boolean immediate)
{
Message m = Message.obtain(mHandler, MESSAGE_TIMEOUT, r);
long delay = immediate ? 0 : (r.duration == Toast.LENGTH_LONG ? LONG_DELAY
: SHORT_DELAY);
mHandler.removeCallbacksAndMessages(r);
mHandler.sendMessageDelayed(m, delay);
}
If you passed in 3000, because 3000 != Toast.LENGTH_LONG, you get a
SHORT_DELAY, which is 2 seconds:
private static final int SHORT_DELAY = 2000; // 2 seconds
IOTW, the code is not expecting milliseconds at all. If you do pass in
milliseconds, it will currently do a 2 second delay. No guarantee as to
what will happen in future releases though.

Well, it seems like if you pass 3000 for the duration, it does show. But the docs don't seem to condone this.

check for internet connection by this method if its returns true then
eecute your code.
public boolean isNetworkAvailable()
{
ConnectivityManager connectivityManager = (ConnectivityManager)
getSystemService
(Context.CONNECTIVITY_SERVICE);
NetworkInfo activeNetworkInfo =
connectivityManager.getActiveNetworkInfo();
return activeNetworkInfo != null;

[android-developers] Re: hi friends
In addition to what bob says: SocketTimeoutException is an IOException. There's a whole bunch of stuff that can go wrong when it comes to IO. The Internet connection could be down, the server you want to contact could be down, the response from the server could be faulty, etc. etc. Your code needs to be able to deal with these problems. Catch the exception and present the user with an error message and provide a retry button. You also may want to check the network connectionhttp://developer.android.com/reference/android/net/ConnectivityManager.htmlif it's currently up and usable.
