Last weekend I started the design process for the first Abduzeedo Android app following Google's Material Design spec. If you follow the post you will remember that I ended with a big question mark: how to create a simple yet discoverable and effective navigation without bloating the UI? It's indeed a tough problem to overcome and I have been thinking a lot about that. In this post I list some references in terms of navigation that I like. Some are aesthetics, others function but I think there are some good ideas.
Also if you have any examples of effective navigation please share with us here on Abduzeedo.
