Should we replace Action Bar by ToolBar?

Question

I have been using ToolBar since it was added into Support v7 library. And I think I used it well. But there is a point I can\'t understand. Why

Answer 1

Yes

The support Toolbar gives you so much more flexibility and freedom, at practically no added extra cost, that there's no reason I can think of not to make the transition. Transitioning to the new Toolbar is actually one of the first steps to porting existing apps to a more Material design, due to the simplicity of the task, and the immediate effect it has on the overall look and feel of the app.
