J jkhazraji Active Member Licensed User Longtime User Nov 17, 2025 #1 Concerning this valuable tutorial: Android Live Wallpaper tutorial, how to 'start' the service WallpaperService to change or set the wall paper. I was not able to run the example althoguh I placed livewallpaper.jar and livewallpaper.xml in internal library folder and added the snippets required in manifest editor, also made the wallpaper.xml read-only! I can only see this code in Button1_Click: B4X: Dim in As Intent in.Initialize("android.intent.action.SET_WALLPAPER", "") StartActivity(in) What makes the app see the service and launch it ?

J jkhazraji Active Member Licensed User Longtime User Nov 17, 2025 #4 I am now starting to comprehend that as the service is run, we should press the screen for some time (in a physical device), in this way the wallpaper invoked by the service should be within the options, or am I wrong? Upvote 0

This file is created during compilation by the call to CreateResource in the manifest editor. The example should work as-is. I've fixed the conflict with the new Initialized keyword. Upvote 0
