Space Flight (compete game+admob+android)

Introduction

Welcome to our comprehensive tutorial on creating a Space Flight game with AdMob integration on Android. In this tutorial, we'll walk you through the entire process of creating a thrilling space combat game, from designing the game to publishing it on the Google Play Store. We'll also cover how to integrate AdMob, a popular mobile advertising platform, to monetize your game.

Prerequisites

Before we begin, please make sure you have the following:

• A computer with Android Studio installed
• A basic understanding of Java and Android development
• A Google Play Games account (optional, but recommended)

Step 1: Setting up the Game

Creating a New Android Studio Project

1. Open Android Studio and select "Start a new Android Studio project"
2. Choose "Empty Activity" and click "Next"
3. Fill in the required information, such as project name, package name, and location
4. Select "Java" as the programming language
5. Click "Finish" to create the project

Designing the Game

1. Create a new layout file activity_main.xml in the res/layout directory

2. Add the following code to the layout file:

   
   <?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">
   
   <SurfaceView
       android:id="@+id/surface_view"
       android:layout_width="match_parent"
       android:layout_height="match_parent"
       android:layout_weight="1" />
   
   <LinearLayout
       android:layout_width="match_parent"
       android:layout_height="wrap_content"
       android:orientation="horizontal">
   
       <Button
           android:id="@+id/pause_button"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Pause" />
   
       <Button
           android:id="@+id/resume_button"
           android:layout_width="wrap_content"
           android:layout_height="wrap_content"
           android:text="Resume" />
   
   </LinearLayout>

This layout file consists of a `SurfaceView` for rendering the game, and two buttons for pausing and resuming the game.

### Creating the Game Logic

1. Create a new Java file `Game.java` in the `java/com.example.yourproject` directory
2. Add the following code to the file:
```java
package com.example.yourproject;

import android.content.Context;
import android.graphics.Canvas;
import android.graphics.Paint;
import android.os.Bundle;
import android.util.AttributeSet;
import android.view.SurfaceHolder;
import android.view.SurfaceView;

public class Game extends SurfaceView implements SurfaceHolder.Callback {

    private Context context;
    private SurfaceHolder surfaceHolder;
    private Paint paint;
    private int width;
    private int height;

    public Game(Context context) {
        super(context);
        this.context = context;
        surfaceHolder = getHolder();
        surfaceHolder.addCallback(this);
        paint = new Paint();
    }

    @Override
    protected void onMeasure(int widthMeasureSpec, int heightMeasureSpec) {
        super.onMeasure(widthMeasureSpec, heightMeasureSpec);
        this.width = widthMeasureSpec;
        this.height = heightMeasureSpec;
    }

    @Override
    public void surfaceCreated(SurfaceHolder holder) {
        // Initialize game logic here
    }

    @Override
    public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
        // Update game logic here
    }

    @Override
    public void surfaceDestroyed(SurfaceHolder holder) {
        // Clean up game logic here
    }

    @Override
    protected void onDraw(Canvas canvas) {
        // Render game graphics here
    }

}

This class extends SurfaceView and implements SurfaceHolder.Callback. It initializes the game logic, updates it when the surface changes, and cleans up when the surface is destroyed. It also provides a method for rendering game graphics.

Step 2: Adding AdMob Integration

Adding the AdMob Library

1. Add the AdMob library to your project by adding the following line to your build.gradle file:

   dependencies {
   implementation 'com.google.android.gms:play-services-ads:19.6.0'
   }

   Creating an AdMob AdUnit

2. Go to the AdMob website and create a new ad unit
3. Fill in the required information, such as ad format, ad size, and targeting
4. Copy the ad unit ID

Adding the AdMob Code

1. Add the following code to your Game.java file:

   
   package com.example.yourproject;

import com.google.android.gms.ads.AdRequest; import com.google.android.gms.ads.AdSize; import com.google.android.gms.ads.AdView; import com.google.android.gms.ads.MobileAds;

public class Game extends SurfaceView implements SurfaceHolder.Callback {

//...

private AdView adView;

@Override
public void surfaceCreated(SurfaceHolder holder) {
    super.surfaceCreated(holder);
    MobileAds.initialize(context, new MobileAds初始化());
    adView = new AdView(context);
    adView.setAdSize(AdSize.SMART_BANNER);
    adView.setAdUnitId("YOUR_AD_UNIT_ID");
    adsLayout.addView(adView);
}

@Override
public void surfaceChanged(SurfaceHolder holder, int format, int width, int height) {
    super.surfaceChanged(holder, format, width, height);
    AdRequest adRequest = new AdRequest.Builder().build();
    adView.loadAd(adRequest);
}

//...

}

This code initializes the AdMob library, creates an AdView, and sets its ad size and ad unit ID. It also loads an ad request when the surface changes.

**Step 3: Testing and Publishing**

### Testing the Game

1. Run the game on an emulator or a physical device
2. Test the game to ensure it runs smoothly and the AdMob ad loads correctly

### Publishing the Game

1. Go to the Google Play Store and create a new game listing
2. Fill in the required information, such as game title, description, and screenshots
3. Upload your game APK file and wait for it to be approved by Google Play

That's it! With these steps, you've created a complete Space Flight game with AdMob integration and published it on the Google Play Store.
