World Capitals Quiz Android Game with AdMob Ads + Ready to Publish

Introduction

Creating a successful Android game involves more than just building an engaging and entertaining game; it also involves effectively integrating ads to monetize the game and provide revenue for developers. AdMob, a popular ad mediation platform, offers a seamless integration process for developers to place ads in their apps and games. In this tutorial, we will go over how to create an interactive World Capitals Quiz game, integrate AdMob ads, and prepare it for publishing on the Google Play Store.

Getting Started with World Capitals Quiz Android Game

To get started with the World Capitals Quiz Android game, we'll begin by creating a new Android project in Android Studio, the official Integrated Development Environment (IDE) for Android app development. You can follow these steps to set up a new project:

1. Launch Android Studio and click on the "Start a new Android Studio project" button.
2. Choose the "Empty Activity" template and enter a project name (e.g., "World Capitals Quiz").
3. Enter a package name, change the language and density as needed, and choose the Android version for which you want to create the project.
4. Click the "Finish" button to create the project.

Once the project is set up, we can begin adding the game functionality and implementing AdMob ads.

Game Functionality and Data

For this tutorial, we'll use a basic game structure consisting of two activities: World Capitals Quiz and GameOver. The game activity contains a list of country capital questions, which will be displayed to the player when the game is played.

Here's the structure for the game's activities:

com.example.worldcapitalsquiz.MainActivity
com.example.worldcapitalsquiz.WorldCapitalsQuizActivity
com.example.worldcapitalsquiz.GameOverActivity

The WorldCapitalsQuizActivity class includes a list of questions from a JSON file (or database) in a formatted text view.

For each question, you have four possible answers from the 250 countries (according to the United Nations data source).

Here are some elements you can define to be displayed in this layout (for example using layouts LinearLayout, Relatively Layout, or others with specific attributes to specify placement and size).

To play the game:

• Answer each question from a series of options.

Next:

1. scoreTotal will track player’s total score.

Let's start writing some sample code for each game method and the classes below them:

import android.os.Bundle;
import android.view.View;
import android.widget.ArrayAdapter;
import android.widget.ListView;

public class WorldCapitalsQuizActivity extends AppCompatActivity {
private ListView listViewCountries;

String[] countriesAndCities={"Afganistan":"Kabul",..."Namibia":};
 int scoreTotal;

Bundle saveInstance;

@Nullable

@Override
protected void onCreate(Bundle savedInstanceState) {
 super.onCreate(savedInstanceState);

this.setTitle("World Capitals Quiz"); // Set Activity's name
setContentView(R.layout.activity_worldcapitals);

// Initialize components (view) and then handle Button's click:
saveInstance=getIntent().getBundleExtra("gameInfo"); // Get extra saved to this Activity before close

if(saveInstance==null){
    startQuiz();// if no Bundle in previous game, initiate New

}
else{  
            String[] listSave=((String[]) saveInstance.getSerializable("SavedInfo"));

            updateAnswersToView(listSave);
      }
}

@override

public void buttonPrevious_Click(View view){} 

And don't forget to call for every click event when implementing, which is:

public void playCountryQuiz(View v)
{//start the question display when user clicks StartQuiz;
  // For an effective AdMob interstitial with your game data here,

    // Update to user’s score to user.score;
    Toast.makeText(v.getContext(), 
                 Toast.makeText(v.getContext(),
                                 "Your 0Score",
                                 3)).show();
