New Activity issuing nullpointerexception
<p>I am trying to start a new activity to display a list of results from a search. I have been through the android dev stuff and androidhive and through similar posts here dealing with populating a listview with an arraylist in a new activity and I just cant seem to get this to work. I would really appreciate any help, been battling with this for a few days now. </p>

<p>Here are the relevants parts of my main activity.</p>

<pre><code>Intent intent = new Intent(this, DisplayResultsActivity.class);
ArrayList&lt;String&gt; myCommonFilms = new ArrayList&lt;String&gt;(commonFilms.getCommonFilms(titleOne, titleTwo));
Log.d("myCommonFilms", myCommonFilms.toString());
intent.putStringArrayListExtra("myCommonFilmsList", myCommonFilms);
startActivity(intent);
</code></pre>

<p>Here is the new activity:</p>

<pre><code>public class DisplayResultsActivity extends Activity {
private ListView listView;

    public void onCreate(Bundle savedInstanceState) {

        setContentView(R.layout.activity_display_results);

        listView = (ListView) findViewById(android.R.id.list);
        Intent intent = getIntent();
        ArrayList&lt;String&gt; myCommonFilms = intent.getStringArrayListExtra("myCommonFilms");
        Log.d("myCommonFilms in display", myCommonFilms.toString());
        Log.d("ArrayListContents", myCommonFilms.toString());
        final ArrayAdapter&lt;String&gt; arrayAdapter = new ArrayAdapter&lt;String&gt;(this, android.R.layout.expandable_list_content, myCommonFilms);
        Log.d("ArrayAdapterContents", arrayAdapter.toString());
        listView.setAdapter(arrayAdapter);  
    }

    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.activity_display_results, menu);
        return true;
    }
}
</code></pre>

<p>Here is my manifest in case something is up there:</p>

<pre><code>&lt;manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.tot.tipofthetongue"
    android:versionCode="1"
    android:versionName="1.0" &gt;

    &lt;uses-sdk android:minSdkVersion="8"
        android:targetSdkVersion="15" /&gt;

    &lt;uses-permission android:name="android.permission.INTERNET" /&gt; 

    &lt;application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@android:style/Theme.NoTitleBar.Fullscreen" &gt;
        &lt;activity
            android:name=".Main"
            android:label="@string/title_activity_main" &gt;
            &lt;intent-filter&gt;
                &lt;action android:name="android.intent.action.MAIN" /&gt;

                &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;
        &lt;activity
            android:name=".DisplayResultsActivity"
            android:label="@string/title_activity_display_results" &gt;

            &lt;intent-filter&gt;
                &lt;action android:name="android.intent.action.MAIN" /&gt;

                &lt;category android:name="android.intent.category.LAUNCHER" /&gt;
            &lt;/intent-filter&gt;
        &lt;/activity&gt;
    &lt;/application&gt;
&lt;/manifest&gt;
</code></pre>

<p>Here is my main activity layout:</p>

<pre><code>&lt;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"
    android:background="@drawable/home_screen_bg" &gt;

    &lt;EditText
        android:id="@+id/searchOne"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentTop="true"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="182dp"
        android:background="@drawable/home_screen_edittext"
        android:ems="10"
        android:inputType="textPersonName" /&gt;

    &lt;Button
        android:id="@+id/findMovies"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_alignParentBottom="true"
        android:layout_centerHorizontal="true"
        android:layout_marginBottom="32dp"
        android:text="@string/buttonText"
        android:onClick="displayResults" /&gt;

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

<p>and lastly the layout of my new activity for displaying the results</p>

<pre><code>&lt;?xml version="1.0" encoding="utf-8"?&gt;
&lt;ListView xmlns:android="http://schemas.android.com/apk/res/android"
    android:id="@id/android:list"
    android:layout_width="fill_parent"
    android:layout_height="fill_parent"
    android:background="@drawable/results_bg"
    android:padding="10dip"
    android:textSize="16dip"
    android:textStyle="bold" &gt;

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

<p>and here is the error log:
