getrootfragment function access modifier

[maqtay]

There are 5 tabs in the app. When the user clicks the back button on some of these tabs, I want to raise an alert without looking at the stack and close the application when the user clicks on this alert. How can I do this? An idea came to my mind, but since the getrootfragment function is private, I cannot access this function and control the tab. Would it be a problem to make this private function public?

You can use NavigatorListener interface. This interface will invoke onTabChanged with tab index.

Both MainActivity and MainActivity2 on :app provides sample implementations for this interface.
