My son sat with me for this stage of development. He is learning programming and was interested in seeing what app development in Android Studio was like. We followed the next steps to add a text field and button to our application and this was the result (with a note from my son):

My First App with Text and Button

The text field can be populated, but the button does not yet work, as the application hasn't been told what to do when the button is selected.
