XMPP Connection with Smack 4.1 on Android Studio

I am trying to do an XMPP Connection with Smack 4.1.0 rc1 from https://github.com/igniterealtime/Smack i followed this guide https://github.com/igniterealtime/Smack/wiki/Smack-4.1-Readme-and-Upgrade-Guide importing the Gradle.

Source code:

import java.io.IOException;

public class MainActivity extends ActionBarActivity {

@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);

// Create the configuration for this new connection
XMPPTCPConnectionConfiguration.Builder configBuilder = XMPPTCPConnectionConfiguration.builder();
configBuilder.setUsernameAndPassword("test@example.com", "password123");
configBuilder.setResource("test");
configBuilder.setServiceName("example.com");

AbstractXMPPConnection connection = new XMPPTCPConnection(configBuilder.build());
// Connect to the server
try {
connection.connect();
} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
} catch (XMPPException e) {
e.printStackTrace();

// Log into the server
try {

} catch (SmackException e) {
e.printStackTrace();
} catch (IOException e) {
e.printStackTrace();
}

// Disconnect from the server
connection.disconnect();
}


@Override

// Inflate the menu; this adds items to the action bar if it is present.
getMenuInflater().inflate(R.menu.menu_main, menu);
return true;
}

@Override

// Handle action bar item clicks here. The action bar will
// automatically handle clicks on the Home/Up button, so long
// as you specify a parent activity in AndroidManifest.xml.

Anyone could help me out with this problem please? I am just trying to check if the connection works..

Answer

Replace smack-java7 with smack-android in your build.gradle. This is documented in Smack's README.
