Android Service with IPC

I have spent the last two days trying to figure this out. I have a service that I am creating to practice with services and IPC. I have checked the code against the book that I am reading it is almost exact only difference being identifiers. I get a ResourcesNotFoundException thrown in the mainwindow.java file. It is thrown when I try to use my IBinder. Any tip in the right direction will be much appreciated.

mainwindow.java

package com.evilOrion;
import com.evilOrion.R;
import android.app.Activity;
import android.content.ComponentName;
import android.content.Context;
import android.content.Intent;
import android.content.ServiceConnection;
import android.os.Bundle;
import android.os.DeadObjectException;
import android.os.IBinder;
import android.os.RemoteException;
import android.util.Log;
import android.view.View;
import android.view.View.OnClickListener;
import android.widget.Button;
import android.widget.TextView;

public class mainwindow extends Activity {
    TextView tView = null;
    Button tButton = null;
    private adder service;
    private boolean bound;

    private ServiceConnection connection = new ServiceConnection(){
        public void onServiceConnected(ComponentName className, IBinder iservice){
            service = adder.Stub.asInterface(iservice);
            bound = true;
        }
        public void onServiceDisconnected(ComponentName className){
            bound = false;
            service = null;
        }
    };

    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        tView = (TextView)findViewById(R.id.TextView);
        tView.setText("hi");

        tButton = (Button)findViewById(R.id.Button01);
        tButton.setOnClickListener(new OnClickListener(){
            public void onClick(View v){
                if(v.equals(tButton)){
                    try{
                        int result = service.add(5, 7);// crashes on this line with no exception
                        tView.setText(result);
                    }catch(DeadObjectException e){
                        Log.i("DeadObjectException", "found the problem"); 
                    }

                    catch(RemoteException e){
                        Log.i("Exception: " , "shoot!");
                    }
                    //tView.setText("What a wonderful day it is");
                }
            }
        });
    }
    public void onStart(){
        super.onStart();
        if(!bound){
            this.bindService(new Intent(mainwindow.this, AdderService.class), connection, Context.BIND_AUTO_CREATE);
        }
    }
    public void onPause(){
        super.onPause();
        if(bound){
            bound = false;
            this.unbindService(connection);
        }
    }
}

AdderService.java

package com.evilOrion;

import android.app.Service;
import android.content.Intent;
import android.os.IBinder;
import android.os.RemoteException;

public class AdderService extends Service {

    private final adder.Stub binder = new adder.Stub() {

        @Override
        public int subtranct(int a, int B) throws RemoteException {
            // TODO Auto-generated method stub
            return  a - b;
        }

        @Override
        public String echo(String input) throws RemoteException {
            // TODO Auto-generated method stub
            return "echo" + input;
        }

        @Override
        public int add(int a, int B) throws RemoteException {
            // TODO Auto-generated method stub
            return  a + b;
        }
    };

    public IBinder onBind(Intent it){
        return this.binder;
    }
}

My Manifest file does have the <service> so I am sure it is not there. I have gone literally line by line between my book and the code and I see 0 differences. I just don't understand what I am doing wrong. One other odd side question. What creates the connection? I get ServiceConnection holds the information on my connection with the two methods onServiceConnected and onServiceDisconnected, but the only place I use connection is in onStart(), does onStart() automatically get called after all other methods are complete. Essentially, I am lost I usually avoid asking questions but I haven't been able to find this answer.

int result = service.add(5, 7); in the mainwindow.java file causes:
No package identifier when getting value for resource number 0x0000000c
09-14 20:36:08.684: INFO/Exception!!!(12446): android.content.res.Resources$NotFoundException: String resource ID #0xc
is thrown in the mainwindow.java

try{
    int result = service.add(5, 7);// crashes on this line with no exception
    tView.setText(result);
}catch(DeadObjectException e){
    Log.i("DeadObjectException", "found the problem"); 
}

Occam's razor in effect. Sometimes you eat the bar and sometimes the bar eats you.

tView doesn't take int values.

Answer:

tView.setText(String.valueOf(result); 

Boy do I feel sheepish a week to find that.
