***Android Studio*** Assignment: Create an android app with 2 buttons, respectively labelled Hello and Goodbye. The user will be able to enter their name into the app (see Lab01 - Android Input & Output). When the Hello button is clicked, the text "Hello" will display lower on the screen, together with the entered name. When the Goodbye button is clicked, the text "Goodbye" will display lower on the screen, together with the entered name. I'm attempting this using a button on click listener and toast widget...am I wrong? It isn't working and I need help
