PreferenceScreen launch activity

I have an activity that I'd like to load from a preference screen. I'm getting the following error:

06-23 16:12:00.470: E/AndroidRuntime(3410): android.content.ActivityNotFoundException:    Unable to find explicit activity class {com.polygonattraction.app/com.polygonattraction.app.functions.GetImageActivity}; have you declared this activity in your AndroidManifest.xml?

My Preference screen code:

         <PreferenceScreen 
        android:title="Get faces"
        android:summary="Get the faces.">

        <intent 
            android:targetClass="com.polygonattraction.app.functions.GetImageActivity"
            android:targetPackage="com.polygonattraction.app" 
         />
    </PreferenceScreen>

Activity I'd like to load

public class GetImageActivity extends Activity 
{
public void onCreate()
{
    System.out.println("Started activity...");
            setContentView(R.layout.actilayout); //not done yet
}

}

Here's my manifest also:

<uses-sdk android:minSdkVersion="7" />

<application 
    android:icon="@drawable/icon"
    android:label="@string/app_name"
    >

    <service
        android:label="@string/app_name"
        android:name=".LiveService"        
        android:permission="android.permission.BIND_WALLPAPER"
        >

        <intent-filter android:priority="1">
            <action android:name="android.service.wallpaper.WallpaperService" />
        </intent-filter>

        <meta-data android:name="android.service.wallpaper" android:resource="@xml/wallpaper" />
    </service>

    <activity
        android:label="settings"
        android:name="com.polygonattraction.app.functions.Settings"
        android:exported="true">
    </activity>

</application>

I'm not good at this Android XML stuff, I'm used to trigga 2d graphics programming. Why have they made it so messy?

You have declared the activity as com.polygonattraction.app.functions.Settings while it's actual name seems to be com.polygonattraction.app.functions.GetImageActivity.

Try using the following in your manifest:

<activity
    android:label="settings"
    android:name="com.polygonattraction.app.functions.GetImageActivity"
    android:exported="true">
</activity>

Instead of 

<activity
    android:label="settings"
    android:name="com.polygonattraction.app.functions.Settings"
    android:exported="true">
</activity>
