NotFoundException for activity_fullscreen
<p>I get an NotFoundException. I already found out with R.java that it is activity_fullscreen which is not found. It is in the same place as it is in the fullscreenactitivty which is created as an example by eclipse which works fine. But mine won't run.
Source:</p>

<pre><code>package com.example.dreamadventure;

import android.app.Activity;
import android.os.Bundle;
import android.os.Handler;
import android.view.MotionEvent;
import android.view.View;
import android.widget.ImageView;
import android.view.View.OnClickListener;

public class FullscreenActivity extends Activity {

    ImageView image;

private static final boolean TOGGLE_ON_CLICK = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);

        setContentView(R.layout.activity_fullscreen);
        final View contentView = findViewById(R.id.fullscreen);

        image = (ImageView) findViewById(R.id.hintergrund);
        image.setImageResource(R.drawable.eulenloch);

    }
}
</code></pre>

<p>XML:</p>

<pre><code>   &lt;View xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@+id/fullscreen" 
    android:layout_height="fill_parent" 
    android:layout_width="fill_parent" 
    android:keepScreenOn="true"
    android:layout_centerHorizontal="true"
    android:background="#FFFFFF" &gt;

    &lt;ImageView android:id="@+id/hintergrund" 
        android:layout_height="wrap_content" 
        android:layout_width="wrap_content" 
        android:layout_centerHorizontal="true"
        android:layout_marginTop="50px"
        android:padding="12dip"
        android:src="@drawable/eulenloch"
        android:background="#FFFFFF"&gt;
    &lt;/ImageView&gt;

  &lt;/View&gt;
</code></pre>

<p>Can anybody tell me what is wrong?</p>
