I am running very simple kaa example on android phone
import android.content.Context;
import android.support.v7.app.AppCompatActivity;
import android.os.Bundle;
import android.widget.Toast;
import org.kaaproject.kaa.client.AndroidKaaPlatformContext;
import org.kaaproject.kaa.client.Kaa;
import org.kaaproject.kaa.client.KaaClient;
import org.kaaproject.kaa.client.SimpleKaaClientStateListener;
import org.kaaproject.kaa.client.exceptions.KaaException;
public class MainActivity extends AppCompatActivity {
private Context mContext;
private KaaClient mClient;
@Override
protected void onCreate(Bundle savedInstanceState) {
super.onCreate(savedInstanceState);
setContentView(R.layout.activity_main);
mContext = this;
mClient = Kaa.newClient(new AndroidKaaPlatformContext(mContext), new SimpleKaaClientStateListener(){
@Override
public void onStarted(){
Toast.makeText(mContext, "Success", Toast.LENGTH_LONG).show();
}
@Override
public void onStartFailure(KaaException exception){
Toast.makeText(mContext, "Failure", Toast.LENGTH_LONG).show();
}
});
mClient.start();
}
}
I am expecting to have a toast telling me if kaa client started successfully or not, but i am not getting any toast, i am not sure what i am doing wrong, the server is running normally
and i can connect to the admin UI from a web browser om my mobile phone is there some steps i should do on the server first? i am running the server built from source code

I found the problem is that i forgot to set public interface on the server to my IP address
sudo nano /etc/kaa-node/conf/kaa-node.propertiestransport_public_interface=localhost=YOUR_PUBLIC_INTERFACE

Hi Mohamed,
I'm also trying to do the same thing and my ip is also configured properly but still not getting any toast message on screen.
Do you have any tutorial for me to follow ?
I tried with the below code just passing true as third parameter to newclient no other changes.
Regards,
Hiten

You can find some tutorial application on the sandbox, just port the code and you should be good to go
