I have added settings to my
live wallpaper but they are not being applied when changed. I would greatly appreciate it if someone could tell me why my settings are not being applied when changed. Here is my code:
settings.xml
<PreferenceCategory android:title="@string/more">
<PreferenceScreen android:title="@string/more">
<intent android:action="android.intent.action.VIEW"
android:data="market://search?q=pub:PSP Demo Center" />
</PreferenceScreen>
<ListPreference
android:persistent="true"
android:enabled="true"
android:entries="@array/settings_light_number_options"
android:title="@string/settings_light_number"
android:key="light_power"
android:summary="@string/settings_light_number_summary"
android:defaultValue="3"
android:entryValues="@array/settings_light_number_optionvalues" />
<ListPreference
android:persistent="true"
android:enabled="false"
android:entries="@array/settings_speed_number_options"
android:title="@string/settings_speed_number"
android:key="speed"
android:summary="@string/settings_speed_number_summary"
android:defaultValue="10"
android:entryValues="@array/settings_speed_number_optionvalues" />
<ListPreference
android:persistent="true"
android:enabled="false"
android:entries="@array/settings_rotate_number_options"
android:title="@string/settings_rotate_number"
android:key="rotate"
android:summary="@string/settings_rotate_number_summary"
android:defaultValue="8000"
android:entryValues="@array/settings_rotate_number_optionvalues" />
</PreferenceCategory>
</PreferenceScreen>

mAnim.setTransformable3D(mCan);
setSkybox(R.drawable.posz, R.drawable.posx,

}
public void onSurfaceCreated(GL10 gl, EGLConfig config) {

settingsUpdater.onSharedPreferenceChanged(preferences, null);

mAnim.start();
}
public void onDrawFrame(GL10 glUnused) {
super.onDrawFrame(glUnused);
mSkybox.setRotY(mSkybox.getRotY() + .5f);
}
}
I know the code is long but I would greatly appreciate any help that someone could give me. Thank you.
