Socket php server not showing messages sent from android client
- by Mj1992
Hi I am a newbie in these kind of stuff but here's what i want to do.
I am trying to implement a chat application in which users will send their queries from the website and as soon as the messages are sent by the website users.It will appear in the android mobile application of the site owner who will answer their queries .In short I wanna implement a live chat.
Now right now I am just simply trying to send messages from android app to php server.
But when I run my php script from dreamweaver in chrome the browser keeps on loading and doesn't shows any output when I send message from the client.
Sometimes it happened that the php script showed some outputs which I have sent from the android(client).But i don't know when it works and when it does not.
So I want to show those messages in the php script as soon as I send those messages from client and vice versa(did not implemented the vice versa for client but help will be appreciated).
Here's what I've done till now.
php script:
<?php
set_time_limit (0);
$address = '127.0.0.1';
$port = 1234;
$sock = socket_create(AF_INET, SOCK_STREAM, 0);
socket_bind($sock, $address, $port) or die('Could not bind to address');
socket_listen($sock);
$client = socket_accept($sock);
$welcome = "Roll up, roll up, to the greatest show on earth!\n? ";
socket_write($client, $welcome,strlen($welcome)) or die("Could not send connect string\n");
do{
$input=socket_read($client,1024,1) or die("Could not read input\n");
echo "User Says: \n\t\t\t".$input;
if (trim($input) != "")
{
echo "Received input: $input\n";
if(trim($input)=="END")
{
socket_close($spawn);
break;
}
}
else{
$output = strrev($input) . "\n";
socket_write($spawn, $output . "? ", strlen (($output)+2)) or die("Could not write output\n");
echo "Sent output: " . trim($output) . "\n";
}
}
while(true);
socket_close($sock);
echo "Socket Terminated";
?>
Android Code:
public class ServerClientActivity extends Activity {
private Button bt;
private TextView tv;
private Socket socket;
private String serverIpAddress = "127.0.0.1";
private static final int REDIRECTED_SERVERPORT = 1234;
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
bt = (Button) findViewById(R.id.myButton);
tv = (TextView) findViewById(R.id.myTextView);
try
{
InetAddress serverAddr = InetAddress.getByName(serverIpAddress);
socket = new Socket(serverAddr, REDIRECTED_SERVERPORT);
}
catch (UnknownHostException e1)
{
e1.printStackTrace();
}
catch (IOException e1)
{
e1.printStackTrace();
}
bt.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
try
{
EditText et = (EditText) findViewById(R.id.EditText01);
String str = et.getText().toString();
PrintWriter out = new PrintWriter(new BufferedWriter(new OutputStreamWriter(socket.getOutputStream())),true);
out.println(str);
Log.d("Client", "Client sent message");
}
catch (UnknownHostException e)
{
tv.setText(e.getMessage());
e.printStackTrace();
}
catch (IOException e)
{
tv.setText(e.getMessage());
e.printStackTrace();
}
catch (Exception e)
{
tv.setText(e.getMessage());
e.printStackTrace();
}
}
});
}
}
I've just pasted the onclick button event code for Android.Edit text is the textbox where I am going to enter my text.
The ip address and port are same as in php script.
