Is it possible to add an app icon , like it shows in Live Aquarium Wallpaper (https://play.google.com/store/apps/details?id=fishnoodle.aquarium_free&feature=search_result#?t=W251bGwsMSwxLDEsImZpc2hub29kbGUuYXF1YXJpdW1fZnJlZSJd) When I install this wallpaper, it shows and icon which opens up the settings page when clicked on it. Has anyone done this before?
You would need to declare an Activity in your AndroidManifest.xml
with the default intent-filter:
<activity
android:name="com.your.company.ui.SettingsActivity"
android:label="@string/app_name" >
<intent-filter>
<action android:name="android.intent.action.MAIN" />
<category android:name="android.intent.category.LAUNCHER" />
</intent-filter>
</activity>
