Sometimes MySQL seems to have trouble starting up automatically. Even though I have the setting for MySql set to start up automatically via the checkbox “Automatically Start MySQL Server on Startup” in System Prefrences - MySQL.

I implemented a bottom navigation bar with multiple fragments. When selecting each view, I added the fragment to the back stack with transaction.addToBackStack(null). However, when I pressed the back button the fragments switched but the menu item in the navigation bar would not highlight.   Apparently, Material design guidelines state “On Android, the Back button does not navigate between bottom navigation bar views.”   As a result I needed to remove the call to addToBackStack as the proper behavior is for the back button to go to the previous app or activity.
