ok, ive done 9patch image has black line on inside, ideas?

i think need try 9patch not have such scaling issues. using 9patch tool android sdk can convert existing png drawables 9patches.

another way use separate resources separate screens (which scale properly). however, lead reduction in apk size. refer screens support topic more information.
