* Jay: Previously, clicking on a sidebar navigation menu item opened a "fragment", which replaced a portion of the screen of the main screen. Over the last week, I have been making brand new activities (which consists of a Java file and a corresponding XML file) and linking the menu options to open a new activity. Now the code for each activity includes the menu button and the top bar (which previously wasn't needed when making a fragment).
Worked on making the sidebar navigation menu options open a new activity (previously, it opened a new fragment).
