This chapter discusses setting up the environment to deploy "Gem Matcher" on an Android-based mobile device. It describes the downloading of additional components from the Android software development kit manager. Unity’s buttons and Input class are smart enough to automatically translate mouse clicks into touch events so that the game will actually be playable without issues.

Unity’s asset store offers different solutions to programmatically rescale things according to the particular device that the game is running on.
