Android Question live wallpaper with declaration of map or list variables

When it crashes you should see in the logs the error you get.
Without posting the complete error from log (or better from unfiltered log too) it is hard to give an concrete advice

As from your date of registration i should ask too which version of b4a you are using?

Most important is the full error from the log i suppose

Ok
One step back.
I tried to install the wallpaper sample/tutorial "LiveWallpaperBall". After installation and open I get a popup message that the application will terminated instead of the toast message

ToastMessageShow("Please go to the home screen and add the Live Wallpaper.", True)

But when i choose the live wallpaper from the menu it will run without an error.

I use the b4a version 2.71, a Nexus7 running 4.4 and i also tried different platforms (14, 17, 19)

And here the unfilterd logcat:
