Wallpaper Settings force close

Question

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!

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!

Thanks! You saved me a wasted hour of my life :) – JesusFreke Sep 01 '11 at 06:18
This helped me too, but after looking into the exported attribute, I think my answer below is better. – gsgx Dec 08 '12 at 01:36
I've just found it too and you confirm it. What a waste of time. – Alexis Pautrot Sep 14 '13 at 13:08

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>

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.

I actually think I found the fix to the problem, but I'm curious about this. Is this permission for the settings activity, or the service itself? My service has the permission of BIND_WALLPAPER right now, not SET_WALLPAPER. Thanks. – Matt Mar 17 '11 at 09:36
You need SET_WALLPAPER permission, if you are setting the wallpaper. – Mudassir Mar 17 '11 at 09:38
Strange, it's working on my device with BIND_WALLPAPER. Is this for the settings activity, or the wallpaper service? Thanks. – Matt Mar 17 '11 at 09:52
