Write an app that consists of a main activity and a HelloWorld activity (you can create the default activity in Android Studio). The main activity UI must have two buttons, labelled "Buzz" and "Toast". When a button is clicked the corresponding UI event must be done. The main activity must have a single menu option that runs HelloWorld when clicked. The main activity must include debugging output to the log. Give the app a personalized icon.
