With latest codes in master branch, when run "samples/ui_demo" on Android emulator, then I get this error.

[master][~/prj/Flow/samples/ui_demo]$ rake android:emulator

Looks like UI::View object in Android actually does not have width= which method should be defined in CSSNode at css_node.c

jjaffeux commented 8 years ago

@Watson1978 looks like it doesn't have any of the css_node methods

anything wrong in https://github.com/HipByte/Flow/blob/master/Rakefile#L52 ? or broken by the last RM ?

Looks like Init_CSSNode in css_node.c would be called at launching and defined CSSNode and methods at least.

However, when use UI::View, looks like it inherits empty class.

Looks for me this is similar with #19
