Application keeps force closing when I try to run in emulator using Eclipse. Help needed

Question

So I am sort of a noob to java and programming at that. I am picking it up however. Recently I have tried to run my app on an emulator but it force closes. It is probably my fault but i can't find any errors. So i decided to turn to you guys since you seem experienced. Any help would be appreciated.

This is the manifest file:

 <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
      package="com.MrNom"
      android:versionCode="1"
      android:versionName="1.0" 
      android:installLocation="preferExternal">


    <application android:icon="@drawable/icon"  android:label="@string/app_name" 
                 android:debuggable="true">
        <activity android:name=".Mr.NomActivity"
                  android:label="@string/app_name" android:screenOrientation="landscape"      android:configChanges="keyboard|keyboardHidden|orientation">
            <intent-filter>

                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>


    </application>


<uses-sdk android:minSdkVersion="3" android:targetSdkVersion="8"/>
    <uses-permission android:name="android.permission.WRITE_EXTERNAL_STORAGE"/>
    <uses-permission android:name="android.permission.WAKE_LOCK"/>
</manifest>

This is the XML:

 <?xml version="1.0" encoding="utf-8"?>
    <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
        android:orientation="vertical"
        android:layout_width="fill_parent"
        android:layout_height="fill_parent"
        android:weightSum="1">
    <TextView android:layout_width="fill_parent" android:textSize="30dp" android:text="Mr. Nom"    android:layout_weight="0.05" android:gravity="center" android:layout_height="wrap_content" android:textStyle="bold"></TextView>
    <Button android:layout_width="160dp" android:text="Play" android:id="@+id/Button02" android:clickable="true" android:layout_weight="0.06" android:layout_height="wrap_content" android:layout_gravity="center" android:textSize="25dp"></Button>
    <Button android:layout_width="160dp" android:text="Settings" android:id="@+id/Button03" android:clickable="true" android:layout_height="wrap_content" android:textSize="25dp" android:layout_gravity="center" android:layout_weight="0.06"></Button>
    <Button android:layout_width="160dp" android:text="Help" android:id="@+id/Button01" android:clickable="true" android:layout_weight="0.06" android:layout_height="wrap_content" android:layout_gravity="center" android:textSize="25dp"></Button>
    <Button android:layout_width="160dp" android:id="@+id/button1" android:clickable="true" android:layout_weight="0.06" android:layout_height="wrap_content" android:textSize="25dp" android:layout_gravity="center" android:text="High Scores"></Button></LinearLayout>

So once again I'm new to this but I thought you guys might need this code. Just let me know if you need anything else.

Heres the activity code:

package Mr;

import com.MrNom.R;
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);
    }

}

When I tried to run the app this was red in logcat.

So to clarify it should look like this:

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);
    }

}

Answer 1

This line:

import com.MrNom.R;

should be

package com.MrNom

And remove the package Mr;

Also in the manifest xml file this line: activity android:name=".Mr.NomActivity" Should be: activity android:name="Mr.NomActivity"
