WARNING: Asset file "widget_theme_android@4x.png" does not exist.

Are you trying to load @3x assets in your config.lua?

Interesting! I hadn’t thought of that. This is the config.lua excerpt:

        imageSuffix =         {             ["@2x"] = 1.5,             ["@3x"] = 2.5,         }

At this time I think we are only providing @2x and @4x assets. If you can adjust your app accordingly, then you can work around the problem.  I’ll see if we are planning @3x assets.
