Are foreground and background colors broken on android for value tiles?

example from the HEM device handler

valueTile("voltsDisp", "device.voltsDisp", width: 2, height: 2) {
	state("default", label: '${currentValue}', 
		foregroundColor: "#000000",
		backgroundColors:[
		[value: "0", color: "#ffffff"],
		[value: "115.6", color: "#bc2323"],
        	[value: "117.8", color: "#D04E00"],
        	[value: "120.0", color: "#44B621"],
        	[value: "122.2", color: "#D04E00"],
        	[value: "124.4", color: "#bc2323"]
    	]
    )
}

and nothing happens… no color
