Why does an error occur when I try to open the live wallpaper settings?

Question

Android

Project on github
When I try to open the wallpaper settings, an error occurred in the "Live Wallpaper Catalog" application.
Android Studio does nothing.
I created an activity, added it to the manifest, added it here

<wallpaper xmlns:android="http://schemas.android.com/apk/res/android"
    android:settingsActivity="ru.siniykv.simplelivewallpaper.SettingsActivity"
    android:thumbnail="@drawable/ic_launcher"
    android:description="@string/wallpaper_description"
    />

What is shown in the logs

>> Открытие просмотра живых обоев
I/WallpaperService: engine created
I/WallpaperService: engine surface created
I/WallpaperService: engine surface changed
I/WallpaperService: engine resumed
I/AndroidInput: sensor listener setup

>> После попытки открыть настройки и закрытия диалогового окна ошибки

Try changing this in your manifest <activity android:name=".SettingsActivity" />
to be like this

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