TicTacToeGame | Basic Tic-Tac-Toe Android Game | Game Engine library

I am getting the following error

I am new to Android. I am creating Tic Tac Toe game and I am getting error while clicking on button to play again. I am enclosing my code.

I want to learn why it is isn't working so I can better help myself next time. The game logic is working fine. When a player won, a layout pop up and congrts player and a button for "play Again" and when I click which call onClickfunction "PlayAgain" on that button it crashes.

This is My MainActivity.java Code:

I need to create a method to check wether the tictactoe game is PLAYING, DRAW, XWIN or OWIN. However, I am having difficulty writing the code to check if X or O has won, given that the size of the gameboard and the size needed to win (sizeWin) are changing according to the user's input. AND I am forced to use a 1D array for the game board. I simply do not know where to go from here. My latest idea was to use nested for loops to check for a win by row, column or diagonal but I'm not sure how to implement it. If anyone has any tips on how to approach this problem or has any other solutions I would be very grateful

I wrote a code for tictactoe game, however it it showing me this error at run time:

total noob with lots of issues with Android Studio.

1. Default Activity error
2. Invalid java package name

Getting a Default Activity error on any app or new project I run - below is an example of the AndroidManifest.xml

"Error running 'app': Default Activity not found"

I have checked more than 100 times I am using the right package names and that my activity is declared in the android manifest

I made a tic tac toe app and I'm suppose to be able to allow the app to rotate without it restarting the app. I learned how to do screen rotation in class, and I have written an OnSaveInstanceState method, however my app keeps crashing. It runs without this method, so I know something is wrong with it however not sure.

I have designed a Tic Tac Toe application on android studio for my app dev class this semester. I first had an issue with my code crashing due to the OnClickListener which I resolved by fixing the buttonMatrix with correct values. My code now opens and runs but I'm having an issue getting my game to advance to the next turn in the game. Basically my app runs and I press the buttons where I want to place either an 'X' or 'O' value depending on if it's player 1 or player 2's turn. My current code only places X's and doesn't advance to player 2's turn and it also doesn't apply my win conditions when I get 3 X's in a row. My current code is as follows:

MainActivity.Java:

I'm trying to do class inheritance in C++, but it obviously works very differently than in Python.

Right now, I have two classes, one called Player that is the base class, and another one called HumanPlayer that's the subclass.

The Player class is an abstract class that has two ways of working.

The first is that it acts like a singleton. It has one static function called make_move that people can call with an int and a TicTacToeGame&, and it will make a move for the player with that int as the player's number in that game of TicTacToe.

The second is that it works as a class for creating objects that have a player number as a property. So, if you construct an object with the class, you should get back an object with a player_number property. Then, if you call the make_move function with just a TicTacToeGame& on the object, it will automatically plug in its player number and use the static class method to make the move in the game.

I want the same functionality for HumanPlayer, except I just want to have to write a new static function for HumanPlayer, and that's it, since the other functionality remains the same.

Here's the code:

I'm brand new to C++ (my usual language is Python).

I found out from here how to print an array. I found out from here how to get a class object to cout as one of its properties. And I found out from here that the cout only works if it can access the class's property as a friend.

But, when I combine the answers, it doesn't seem to work. Here's what I've got:
