I know there are many tools/frameworks in RubyMotion, such as: Bubblewrap, AFMotion. (refer to: http://siwei.me/blog/posts/rubymotion-2-must-have-libraries-for-rubymotion-part2 ) , but when I googled around for the similar tools in Ruboto (Ruby on Android) I didn't see any result.
Could someone give me a clue? thanks a lot.
There are few (none?) Ruboto-specific libraries that I know of, but you can use all the Android tools and libraries in addition to all Java tools and libraries that do not target Java 7/8 or JNI, and you can use all pure Ruby gems, and gems targeting JRuby.
Ruboto itself is bundled with ruboto/widget which is a DSL for creating UI layouts.
