App keeps force closing each time I try to run. Help needed.

When I try to run this code it force closes. And I apologize in advance because I am a noob at java.

package com.MrNom;

import android.app.Activity;
import android.os.Bundle;

public class NomActivity extends Activity {
    /** Called when the activity is first created. */
    @Override
    public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
    }

}

This was red in LogCat right before it force closed.

In your AndroidManifest.xml, find where you declare that activity and change it's name property from "com.MrNom.Mr.NomActivity" to "com.MrNom.NomActivity".

As you can see from your activity class, it's in package "com.MrNom", not "com.MrNom.Mr"

to me it seems that you somehow messed up the namespaces - in the exception it says that it tries to create com.MrNom.Mr.NomActivity which is not found... the correct class would be (just a guess) com.MrNom.NomActivity - somewhere you make the runtime beleive there must be Mr. in there - you don't show enough code to solve this...
