Wallpaper Settings force close

I'm having a force close problem whenever I try to launch the settings for my live wallpaper. I don't really have anything there, so I'm not sure what could possibly be causing the problem... Here is the logCat

I think it's that permission denial line, but I have no clue what could be causing it... Is there some hidden permission I need to set? This is my first liveWallpaper.

Thanks!

While the accepted answer definitely works, it's not the correct way to do it. Setting export to true just means the activity can be launched outside of your application. However, the way this should be done is to declare the activity like this:

    <activity android:name="com.example.SettingsActivity" >
        <intent-filter>
            <action android:name="android.intent.action.MAIN" />
        </intent-filter>
    </activity>

Ugh, I found the problem... It turns out I needed the preference activity in the manifest have exported set to "true". There's an hour I'll never get back!

Yes, you need to set the SET_WALLPAPER permission in Android manifest file. You can use the following line inside the <manifest></manifest> element;

<uses-permission android:name="android.permission.SET_WALLPAPER" />

Update:

Reference: <uses-permission> element.
