  • You should be more specific what you are doing. Are you using `roScreen` or `roImageCanvas` or is this about one of the dialog screens? – Nas Banov Mar 15 '15 at 16:53

You cannot set custom background images for any of the built-in screens, only a background color. You can fake it for roListScreen by setting the HDBackgroundImageUrl/SDBackgroundImageUrl content metadata for every item, but that can make the screen incredibly sluggish to navigate.

Just use setLayer(0, ...) for the background.

I.e. put the background image in the farthest layer (doesn't have to be z-order 0 but i picked this as example since it's the last visible layer).

  • [roDeviceInfo.getDisplaySize()](http://sdkdocs.roku.com/display/sdkdoc/ifDeviceInfo#ifDeviceInfo-GetDisplaySizeasObject) and the three previous methods, i think – Nas Banov Mar 19 '15 at 04:37
