Prerequisites

Before starting this tutorial, make sure you have the following:

1. Android Studio installed on your computer
2. Basic knowledge of Java or Kotlin programming language
3. A Google Play Developer account
4. A AdMob account

Step 1: Setting up the game environment using Android Studio

1. Open Android Studio and create a new project by selecting "File" > "New" > "New Project"
2. Choose "Empty Activity" as the project template and click "Next"
3. Fill in the project details, such as project name, package name, and target SDK
4. Click "Finish" to create the project

Step 2: Creating the game UI and gameplay logic

1. Open the activity_main.xml file and add the following code to create the game UI:

   
   <?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">
   
   <ImageView
       android:id="@+id/game_surface"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:scaleType="centerCrop" />
   
   <Button
       android:id="@+id/jump_button"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:text="Jump" />

2. Open the `MainActivity.java` file and add the following code to create the gameplay logic:
```java
public class MainActivity extends AppCompatActivity {
    private ImageView gameSurface;
    private Button jumpButton;
    private int playerY = 0;
    private int obstacleY = 0;

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

        gameSurface = findViewById(R.id.game_surface);
        jumpButton = findViewById(R.id.jump_button);

        jumpButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View v) {
                playerY -= 20;
                gameSurface.setY(playerY);
            }
        });

        // Initialize obstacle movement
        new Timer().scheduleAtFixedRate(new TimerTask() {
            @Override
            public void run() {
                obstacleY += 5;
                gameSurface.setY(obstacleY);
            }
        }, 0, 100);
    }
}

Step 3: Integrating AdMob for banner and interstitial ads

1. Create a new AdMob account and get your AdMob ID
2. Add the AdMob SDK to your project by adding the following code to your build.gradle file:

   dependencies {
   implementation 'com.google.android.gms:play-services-ads:20.2.0'
   }

3. Open the activity_main.xml file and add the following code to display the banner ad:

   
   <LinearLayout
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:orientation="vertical">
   
   <!-- Game UI and gameplay logic -->
   
   <com.google.android.gms.ads.AdView
       android:id="@+id/adView"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="10dp"
       ads:adSize="BANNER"
       ads:adUnitId="YOUR_AD_UNIT_ID" />

4. Open the `MainActivity.java` file and add the following code to load the banner ad:
```java
AdView adView = findViewById(R.id.adView);
AdRequest adRequest = new AdRequest.Builder().build();
adView.loadAd(adRequest);

Step 4: Implementing Reward Video ads

1. Create a new AdMob account and get your AdMob ID
2. Add the AdMob SDK to your project by adding the following code to your build.gradle file:

   dependencies {
   implementation 'com.google.android.gms:play-services-ads:20.2.0'
   }

3. Open the activity_main.xml file and add the following code to display the reward video ad:

   
   <LinearLayout
   android:layout_width="match_parent"
   android:layout_height="wrap_content"
   android:orientation="vertical">
   
   <!-- Game UI and gameplay logic -->
   
   <com.google.android.gms.ads.VideoController
       android:id="@+id/videoController"
       android:layout_width="wrap_content"
       android:layout_height="wrap_content"
       android:layout_marginBottom="10dp" />

4. Open the `MainActivity.java` file and add the following code to load the reward video ad:
```java
VideoController videoController = findViewById(R.id.videoController);
AdRequest adRequest = new AdRequest.Builder().build();
videoController.loadAd(adRequest);

Step 5: Adding In-app purchases using Google Play Billing

1. Create a new Google Play Developer account and get your developer account ID
2. Add the Google Play Billing SDK to your project by adding the following code to your build.gradle file:

   dependencies {
   implementation 'com.android.billingclient:billing:4.0.0'
   }

3. Open the MainActivity.java file and add the following code to purchase an in-app item:

   BillingClient billingClient = BillingClient.newBuilder(this).setListener(new BillingClientStateListener() {
   @Override
   public void onBillingSetupFinished(BillingResult billingResult) {
       if (billingResult.getResponseCode() == BillingClient.BillingResponseCode.OK) {
           // Purchase an in-app item
           BillingFlowParams flowParams = BillingFlowParams.newBuilder()
                  .setProductDetailsList(Arrays.asList(ProductDetails.newBuilder()
                          .setProductId("YOUR_PRODUCT_ID")
                          .setQuantity(1)
                          .build()))
                  .build();
           billingClient.launchBillingFlow(this, flowParams);
       }
   }
   }).build();
   billingClient.startConnection();

   Step 6: Creating a Leaderboard using Google Play Games Services

4. Create a new Google Play Developer account and get your developer account ID
5. Add the Google Play Games Services SDK to your project by adding the following code to your build.gradle file:

   dependencies {
   implementation 'com.google.android.gms:play-services-games:20.2.0'
   }

6. Open the MainActivity.java file and add the following code to create a leaderboard:

   Games games = Games.getGamesClient(this);
   Leaderboard leaderboard = games.getLeaderboardClient();
   leaderboard.loadScores(LeaderboardPreset.RATING_TOP_LEVEL, LeaderboardTimeSpan.ALL_TIME, LeaderboardCollection.USUAL);

   Step 7: Testing and publishing the game on the Google Play Store

7. Test the game on various devices and emulators to ensure it works as expected
8. Optimize the game for different screen sizes and densities
9. Create a game icon and splash screen
10. Write a game description and set the game's price
11. Publish the game on the Google Play Store

That's it! With these steps, you should now have a fully functional Jump Up game that is ready to publish on the Google Play Store.
