This Android program displays a simple "Hello World" message. It creates an activity called MainActivity that extends the base Activity class and overrides its onCreate and onCreateOptionsMenu methods. On create, it calls the super method and sets the content view to the activity_main layout. The menu inflater is used to inflate any menu items on create options menu.
