Watchface multiple resolution background image

Hi,

I have following issue:

I try to make a backgroud image available for 240x240, 260x260 and 280x280 round devices. If i load and run one image from drawables folder is ok, but when i add resource folders:

resources-round-240x240, resources-round-260x260, etc and put on each folder the designated file along with drawables.xml, i get the Out of memory error, failed invoking symbol.

Please point me in the right direction.
