Unfortunately, *name of app* has stopped

I have just started programming, and I am making an android version of the swedish law book. I have no errors in the code, but when I try to run it in the emulator, it starts up, but as soon as a press a button it says "Unfortunately, name of app has stopped."

I have looked through many other threads like this, but they have all been code specific and therefore of no use to me.

I am using Eclipse.

So, I was wondering if any kind soul could just look through what I have done a help me find a mistake?

This is the "Activity_Main_activity.xml" coding:

    <RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
xmlns:tools="http://schemas.android.com/tools"
android:layout_width="match_parent"
android:layout_height="match_parent"
tools:context=".HuvudMeny" >

<Button
    android:id="@+id/button1"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    android:layout_alignParentLeft="true"
    android:layout_alignParentRight="true"
    android:layout_alignParentTop="true"
    android:text="Kapitel 1, Om Brott och Brottspåföljder"
    android:onClick = "kapett" />

As you can see, its very simple.

Here is the MainActivity.java coding:

    import com.example.brottsbalken.Kap1;

    import android.os.Bundle;
    import android.app.Activity;
    import android.content.Intent;
    import android.view.Menu;
    import android.view.View;

    public class HuvudMeny extends Activity {

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

@Override
public boolean onCreateOptionsMenu(Menu menu) {
    // Inflate the menu; this adds items to the action bar if it is present.
    getMenuInflater().inflate(R.menu.activity_huvud_meny, menu);
    return true;
}



    public void kapett(View view) {
Intent intent1 = new Intent(this, Kap1.class);
startActivity(intent1);

EDIT: Added LogCat. Did not know you needed this, sorry!

Here is the manifest, it looks pretty correct to me...

    <?xml version="1.0" encoding="utf-8"?>
    <manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="nackagymnasium.brottsbalken2"
    android:versionCode="1"
    android:versionName="1.0" >

<uses-sdk
    android:minSdkVersion="8"
    android:targetSdkVersion="17" />

<application
    android:allowBackup="true"
    android:icon="@drawable/ic_launcher"
    android:label="@string/app_name"
    android:theme="@style/AppTheme" >
    <activity
        android:name="nackagymnasium.brottsbalken2.HuvudMeny"
        android:label="@string/app_name" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />

            <category android:name="android.intent.category.LAUNCHER" />
        </intent-filter>
    </activity>
    <activity
        android:name="nackagymnasium.brottsbalken2.Kap1"
        android:label="@string/title_activity_kap1" >
    </activity>

I changed the name of "Main Activity" to "Huvud Meny".

I figuered it must be something wrong with the Intent (genius), but I have no idea what it is.

If someone took their time and helped me I would be very happy!

Have you declared this activity in your AndroidManifest.xml ?

Well, did you ?

See Add a new activity to the AndroidManifest?
