In this tutorial, we will develop a super cool Tic-Tac-Toe in android studio that is impossible to beat.
Must be thinking why impossible! Because we are going to use Artificial Intelligence in this game.
Creating Tic-Tac-Toe in Android Studio
- Create a new project by going to File ⇒ New Android Project. and fill the required details.
- Implement your main Activity class from TicTacToe.OnInitListener
- Now add following code your class
