There are a lot of things happening here, RenderThemeHandler is parsing render theme, hill shading is reading from ZIPs and rendering in high quality, your app is doing something, probably some map animation is going on, but the exact line where the error occurs is still not clear. As you said, this probably has nothing to do with hill shading, other than the fact that it's easier to recreate the error when hill shading is actively using resources. Can you somehow pinpoint the exact line of code where this is happening, so we know which bitmap the error is referring to? Since the error is coming from HWUI, it's probably a map View issue, but... (One thing to note, render theme parsing cannot be interrupted, it is not implemented. Maybe this could help.)
