Yep. But why do u use main function twice and there are no Threads?

try moving the while loop just before the message = infromserver.readline().

your current code creates thousands of inputStreanReaders and bufferReaders.
also make sure when sending you end your strings with n since you are using the readline method.
if it still isn’t fixed try after sending calling the .flush() mehod on the dataoutputstream (if such method exists not sure)

hi i am new in Java and android…my app is not working , i can connect and send data to the server( PC .net server)

the server send me ” 3 string”

through your code … i wrote this solution but it is not working :

while(true){

try {

BufferedReader inFromServer = new BufferedReader(new InputStreamReader(sock.getInputStream()));

message = inFromServer.readLine();

Toast.makeText(client.this, message,Toast.LENGTH_LONG).show();

} catch (IOException e) {

// TODO Auto-generated catch block

Toast.makeText(client.this, “not working”,Toast.LENGTH_LONG).show();

e.printStackTrace();

}

can you tell me what’s wrong… Please

the out put is whatever you type into the client via this line in the code:

sentence = inFromUser.readLine();
outToServer.writeBytes(sentence + ‘n’);

hi, if you run the client, then type something like “hello world” and then press enter, the server and the client will respond (only obvious if you read the code)

Best simple code!

@Bhanusankar Bsc
The input string in uppercase:
System.out.println(“Received: ” + clientSentence);
capitalizedSentence = clientSentence.toUpperCase() + ‘n’;
outToClient.writeBytes(capitalizedSentence);//response to the client
