Android Livewallpaper settings fail to load from 'configure…' menu

问题

I am unable to load the live wallpaper preferences from 'Wallpaper>Configure...'.

The preferences load fine when i click the settings button from within the Livewallpaper menu. Here are some screen shots to better explain the error:

figured it out after tinkering around with the manifest file. Added an intent filter 'category.PREFERENCE' & moved BIND_WALLPAPER permission inside the service tag. here is the new manifest file:

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
  package="com.android.RrD"
  android:versionCode="1"
  android:versionName="1.0">

<uses-sdk android:minSdkVersion="8" />

<uses-feature android:name="android.software.live_wallpaper" />

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

<uses-permission android:name="android.permission.ACCESS_FINE_LOCATION" />
<uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION" />
<uses-permission android:name="android.permission.BIND_WALLPAPER" />
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE" />

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

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

        <intent-filter>
            <action android:name="android.service.wallpaper.WallpaperService" />
        </intent-filter>
        <meta-data android:name="android.service.wallpaper"
            android:resource="@xml/livewallpaper" />

    </service>

<activity android:label="PAM_Prefs"
        android:name=".PAM_Prefs" 

        android:exported="true" android:icon="@drawable/icon">
         <intent-filter>

            <category android:name="android.intent.category.PREFERENCE" />
        </intent-filter>
    </activity>

</application>
</manifest>
