Android - Snackbar vs Toast - usage and difference

Question

We have been using just Toasts in our application so far and as we are planning to adopt some new features from Support Design Library I am wondering what\'s the recommended

Answer 1

Google's Material Design Specification says that it's ok to have a Snackbar without an action. They have provided examples of what a Snackbar should look like if it only displays a single String. I would assume that "System Messaging" means device events like network connection being lost - whereas archiving an email is a Gmail specific action, for example.

For consistency's sake, it makes sense to pick either a Toast or a Snackbar, and apply that throughout your app.
