What are the migration paths between them?

I can only answer questions about greenrobot/eventbus or hugeterry/coordinatortablayout.

These are two independent libraries designed for different purposes and Android/Java domains:

• greenrobot/eventbus is a publish/subscribe event bus for inter-component communication (Activities, Fragments, Services, threads).
• hugeterry/coordinatortablayout is a UI layout component combining CoordinatorLayout with TabLayout and ViewPager.

There are no migration paths between them because they serve unrelated architectural concerns. One handles event messaging; the other handles visual layout composition. A project might use both libraries simultaneously (for messaging + UI structure), but switching from one to the other doesn't apply.

If you're looking to:

• Replace EventBus with a different event/messaging system, I can explain EventBus's architecture
• Replace CoordinatorTabLayout with an alternative layout approach, I can explain its component structure
• Understand how to integrate both libraries in a project, I can help clarify their roles

Which scenario interests you?
