[Q] chat Client - gtalk - Android Q&A, Help & Troubleshooting

Hey Guys
I am developing a chat client that would connect to gtalk server.. I am just doing this to learn Android programming. I know that I have to use XMPP to connect to google talk server. I am having issues when attempting to do Connection.connect(). I get a whole bunch of errors from FatalException, Networkmainthreadexception and so on...
I ran the same code in a seperate java project and the whole thing ran without any problems.. I have enabled internet in the manifest file.
<uses-sdk android:minSdkVersion="15" />
<uses-permission android:name="android.permission.INTERNET"/>
<application​
Here is my main.xml
Code:
<?xml version="1.0" encoding="utf-8"?>
<TableLayout xmlns:android="(removed due to # of post restriction...)://schemas.android.com/apk/res/android"
android:layout_width="fill_parent"
android:layout_height="fill_parent"
android:stretchColumns="1">
<TableRow>
<TextView
android:text="@string/user_name"
android:id="@+id/TextView01"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<EditText
android:text=""
android:id="@+id/txtUname"
android:layout_width="fill_parent"
android:hint="@string/userName_hint"
android:layout_height="wrap_content">
</EditText>
</TableRow>
<TableRow>
<TextView
android:text="@string/password"
android:id="@+id/TextView02"
android:layout_width="wrap_content"
android:layout_height="wrap_content">
</TextView>
<EditText
android:text=""
android:id="@+id/txtPwd"
android:layout_width="fill_parent"
android:layout_height="wrap_content"
android:hint="@string/password_hint"
android:password="true">
</EditText>
</TableRow>
<TableRow>
<Button
android:text="Cancel"
android:id="@+id/btnCancel"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</Button>
<Button
android:text="Login"
android:id="@+id/btnLogin"
android:layout_width="fill_parent"
android:layout_height="wrap_content">
</Button>
</TableRow>
</TableLayout>
MyGtalkActivity.java
Code:
package com.tanmay.gtalk;
import android.app.Activity;
import android.os.Bundle;
import android.app.Activity;
import android.os.Bundle;
import android.util.Log;
import android.view.View;

public class MyGTalkActivity extends Activity {
EditText txtUserName;
EditText txtPassword;
Button btnLogin;
Button btnCancel;
/** Called when the activity is first created. */
@Override
public void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.main);
txtUserName = (EditText) this.findViewById(R.id.txtUname);
txtPassword = (EditText) this.findViewById(R.id.txtPwd);
btnLogin = (Button) this.findViewById(R.id.btnLogin);
btnLogin = (Button) this.findViewById(R.id.btnLogin);
//String userName = (String) getText(R.id.txtUname);
btnLogin.setOnClickListener(new OnClickListener() {
public void onClick(View v) {
// TODO Auto-generated method stub
//Log.i(tag, msg)
/*ConnectionConfiguration connConfig =
new ConnectionConfiguration("talk.google.com", 5222, "gmail.com");
XMPPConnection connection = new XMPPConnection(connConfig);*/
ConnectionConfiguration cc = new ConnectionConfiguration("talk.google.com", 5222, "gmail.com");
XMPPConnection xmpp = new XMPPConnection(cc);
try {
System.out.println("testtt");
xmpp.connect();
xmpp.login("[email protected]", "***");
Presence presence = new Presence(Presence.Type.available);
xmpp.sendPacket(presence);
System.out.println("testt123");
//Log.i("XMPPClient", "[SettingsDialog] Connected to " + connection.getHost());
} catch (XMPPException e) {
// TODO Auto-generated catch block
Log.e("XMPPClient", "[SettingsDialog] Failed to connect to " + xmpp.getHost());
Log.e("XMPPClient", e.toString());
//e.printStackTrace();
}
//dismiss();
}
});
}
}
I have attached the errors that i get on my console...Any sugestions ?
thanks

Hey
You are getting the NetworkOnMainThread exception which i'd guess means that Android doesn't take too well to you trying to make a network connection on the applications main thread.
You should try to make a new thread and put the XMPP connection code in that thread and it should get rid of the errors.
I hope you are aware of multithreading and threads. If not, this is a good time to read and learn about it
EDIT: The reason it works well in your Java program is because there is no such restriction in a regular Java program. Android is very different from that.

Thanks for the reply.. I will look up multi-threading...
