Tic Tac toe Gallery – Android App + Admob + Facebook Integration

Introduction

Welcome to this comprehensive tutorial on creating a Tic Tac Toe game for Android using the Tic Tac Toe Gallery app, integrating AdMob for monetization, and Facebook for social sharing. In this tutorial, we will cover the steps to create a Tic Tac Toe game from scratch, integrate AdMob for displaying ads, and connect it to Facebook for sharing scores and achievements.

Prerequisites

Before we begin, make sure you have the following:

• Android Studio installed on your computer
• Basic knowledge of Java or Kotlin programming language
• Familiarity with Android development and Android Studio
• A Facebook Developer account and a Facebook App created
• A Google AdMob account and a AdMob App created

Step 1: Creating the Tic Tac Toe Game

Create a new Android project in Android Studio and name it "Tic Tac Toe". Create a new activity called "MainActivity" and add the following code:

public class MainActivity extends AppCompatActivity {

    private TicTacToeView ticTacToeView;
    private boolean isXTurn = true;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        ticTacToeView = findViewById(R.id.tic_tac_toe_view);
        ticTacToeView.setOnTouchListener(new View.OnTouchListener() {
            @Override
            public boolean onTouch(View v, MotionEvent event) {
                int row = (int) event.getY() / ticTacToeView.getHeight() / 3;
                int col = (int) event.getX() / ticTacToeView.getWidth() / 3;
                if (isXTurn) {
                    ticTacToeView.setCell(row, col, "X");
                    isXTurn = false;
                } else {
                    ticTacToeView.setCell(row, col, "O");
                    isXTurn = true;
                }
                return true;
            }
        });
    }
}

This code creates a Tic Tac Toe game with a 3x3 grid and allows the user to play the game by touching the cells.

Step 2: Adding AdMob

To add AdMob to your app, follow these steps:

• Create a new AdMob App in the Google AdMob dashboard
• Create a new Ad Unit and select the "Banner" ad format
• Add the AdMob SDK to your Android project by adding the following dependency to your build.gradle file:

  dependencies {
  implementation 'com.google.android.gms:play-services-ads:20.5.0'
  }

• Add the AdMob ad view to your activity layout:

  
  <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical">
  
  <com.google.android.gms.ads.AdView
      android:id="@+id/adView"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content"
      app:adSize="BANNER"
      app:adUnitId="YOUR_AD_UNIT_ID" />
  
  <com.example.tictactoe.TicTacToeView
      android:id="@+id/tic_tac_toe_view"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

* Initialize the AdMob ad view in your activity:
```java
AdView adView = findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);

Step 3: Integrating Facebook

To integrate Facebook with your app, follow these steps:

• Create a new Facebook App in the Facebook Developer dashboard
• Create a new Facebook Login and add the Facebook SDK to your Android project by adding the following dependency to your build.gradle file:

  dependencies {
  implementation 'com.facebook.android:facebook-android-sdk:8.2.0'
  }

• Add the Facebook login button to your activity layout:

  
  <?xml version="1.0" encoding="utf-8"?>
  <LinearLayout xmlns:android="http://schemas.android.com/apk/res/android"
  xmlns:app="http://schemas.android.com/apk/res-auto"
  android:layout_width="match_parent"
  android:layout_height="match_parent"
  android:orientation="vertical">
  
  <com.facebook.login.widget.LoginButton
      android:id="@+id/login_button"
      android:layout_width="wrap_content"
      android:layout_height="wrap_content" />
  
  <com.example.tictactoe.TicTacToeView
      android:id="@+id/tic_tac_toe_view"
      android:layout_width="match_parent"
      android:layout_height="match_parent" />

* Initialize the Facebook login button in your activity:
```java
LoginButton loginButton = findViewById(R.id.login_button);
loginButton.setReadPermissions(Arrays.asList("public_profile", "email"));
loginButton.registerCallback(callbackManager, new FacebookCallback<LoginResult>() {
    @Override
    public void onSuccess(LoginResult loginResult) {
        // Login successful, get the user's profile information
        GraphRequest request = GraphRequest.newMeRequest(
                loginResult.getAccessToken(),
                new GraphRequest.GraphJSONObjectCallback() {
                    @Override
                    public void onCompleted(JSONObject object, GraphResponse response) {
                        // Get the user's profile information
                        String name = object.getString("name");
                        String email = object.getString("email");
                        // Share the user's score on Facebook
                        ShareLinkContent content = new ShareLinkContent.Builder()
                               .setContentUrl(Uri.parse("https://example.com"))
                               .setContentTitle("Tic Tac Toe Score")
                               .setContentDescription("I scored " + getScore() + " in Tic Tac Toe!")
                               .build();
                        ShareDialog shareDialog = new ShareDialog(MainActivity.this);
                        shareDialog.show(content);
                    }
                });
        request.executeAsync();
    }

    @Override
    public void onCancel() {
        // Login cancelled
    }

    @Override
    public void onError(FacebookException e) {
        // Login error
    }
});

Step 4: Implementing the Game Logic

Implement the game logic by adding the following code to your activity:

private int score = 0;

public int getScore() {
    return score;
}

public void setScore(int score) {
    this.score = score;
}

public void checkForWin() {
    // Check if the game is won
    if (ticTacToeView.getWinner()!= null) {
        // Game won, increment the score
        setScore(getScore() + 1);
        // Share the score on Facebook
        ShareLinkContent content = new ShareLinkContent.Builder()
               .setContentUrl(Uri.parse("https://example.com"))
               .setContentTitle("Tic Tac Toe Score")
               .setContentDescription("I scored " + getScore() + " in Tic Tac Toe!")
               .build();
        ShareDialog shareDialog = new ShareDialog(MainActivity.this);
        shareDialog.show(content);
    }
}

Step 5: Testing the App

Test the app by running it on an emulator or a physical device. Make sure to test the AdMob ads and Facebook login functionality.

Conclusion

In this tutorial, we have created a Tic Tac Toe game for Android using the Tic Tac Toe Gallery app, integrated AdMob for monetization, and connected it to Facebook for sharing scores and achievements. We have also implemented the game logic and tested the app. With this tutorial, you should be able to create your own Tic Tac Toe game with AdMob and Facebook integration.
