I was doing it with the following code:
in which I used “display.newImage(“android.app.icon://”…PackageName)” to find out if the app existed, but in android 13 that doesn’t work for me
function libreriasUI:AppInstalada(PackageName)
	local appIcon = display.newImage("android.app.icon://"..PackageName)
	if appIcon then
	   -- App is installed.
	   appIcon.isVisible = false
	   display.remove(appIcon)
	   return true
	else
	   -- App is not installed.
	   display.remove(appIcon)
	   return false
	end
end
