This document contains instructions for two Android Kotlin programming assignments. The first assignment asks students to update text in a background thread. The second assignment involves creating a timer app with a text view to display the time, and start and stop buttons to control the timer. Students are to submit zipped project files for the two apps by November 25th at 23:59:59. It also provides partial code for a timer app class that uses a Handler and thread to update the text view periodically, and notes that the start and stop button click listeners need to be completed to control the timer updating.
