Poker (Admob + GDPR + Android Studio)

Introduction

The world of online poker! With the rise of smartphones and mobile gaming, introducing a poker game to mobile devices has become a desirable and lucrative venture. If you're an Android app developer, you can't miss the opportunity to create a poker game that can generate income through in-app advertisements with AdMob, while still complying with the General Data Protection Regulation (GDPR) requirements. In this tutorial, we'll cover the steps to create a poker game using Android Studio, integrate AdMob to display ads, and handle GDPR compliance.

Required Knowledge

Before starting, make sure you have basic knowledge of:

1. Android development using Java or Kotlin
2. Understanding of AdMob and AdMob SDK
3. Familiarity with the GDPR regulations

Objective

The objective of this tutorial is to create a simple poker game that complies with GDPR regulations, integrates AdMob for revenue generation, and is functional on Android devices.

Step 1: Set up the Project

Let's start by creating a new project in Android Studio. Follow these steps:

1. Open Android Studio and click on "New" > "New Project"
2. Choose the "Empty Activity" template and name your project
3. Set the Android version to the latest and the language to Java (or Kotlin if you prefer)
4. Click on "Finish" to create the project

Step 2: Create a New Activity

We will create a new activity called "PokerActivity.java" (or "PokerActivity.kt" if you're using Kotlin). This activity will host our poker game.

1. Right-click on the project directory > "New" > "Java Class" (or "New" > "Kotlin Class" if you're using Kotlin)
2. Name the class "PokerActivity" and press "Enter"
3. Add the following code (or equivalent in Kotlin):

import androidx.appcompat.app.AppCompatActivity;
import android.os.Bundle;

public class PokerActivity extends AppCompatActivity {

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

Step 3: Design the UI

In this step, we will design the user interface of our poker game. Open the "activity_poker.xml" file and modify it as follows:

1. Add a RelativeLayout (or any other layout manager you prefer) to create a layout for our UI
2. Add text views for displaying the result, a button for performing the action, and labels for displaying the input message
3. Modify the layout as needed to your liking

Step 4: Integrate AdMob

To integrate AdMob, we need to add the AdMob Android SDK to our project and initialize it. Follow these steps:

1. Create a new file called "AdMob.java" in the "java" folder of your project:
2. Add the following code:

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

public class AdMob {
    private AdView adView;

    public AdMob(PokerActivity activity) {
        this.adView = new AdView(activity);
        MobileAds.initialize(activity, "");
        adView.setAdSize(AdSize.SMART_BANNER);
    }

    public void LoadAd() {
        AdRequest adRequest = new AdRequest.Builder().build();
        adView.loadAd(adRequest);
    }

    public AdView getAdView() {
        return adView;
    }
}

Step 5: Handle GDPR Compliance

The GDPR requires that users can opt-out of data sharing and that they are fully informed about the data shared. To comply with the GDPR, we will use the Google Play Services Targeting API to provide functionality for users to opt-in or opt-out of targeting.

1. Add the Google Play Services Targeting API to your project in the build.gradle file as follows:

dependencies {
   ...
    implementation 'com.google.firebase:firebase-core:10.2.0'
    implementation 'com.google.firebase:firebase-ads:10.2.0'
    implementation 'com.google.android.gms:play-services-ads-identity:10.2.0'
}

1. Create a method to handle the opt-out functionality:

import com.google.android.gms.identity.intents.zza.zzb;

public class UserData {
    public static zzd get() {
        return zzd.zzawL();
    }

    public static void set(Iterable<String> iterable) {
        zzd.zzc(iterable);
    }

    public static boolean isVisible() {
        return isGooglePlayServicesAvailableP();
    }

    @TargetApi(18)
    private static boolean isGooglePlayServicesAvailableP(Context context) {
        Intent intent = new Intent(Settings.ACTION_OPEN_BY_DEFAULT_CLIENT);
        intent.setComponent(new ComponentName("com.google.android.gms", "com.google.android.gms.id.intents.zza"));;
        PackageManager packageManager = context.getPackageManager();

        List<ResolveInfo> list = packageManager.queryIntentActivities(intent, 0);
        intent.setComponent(null);
        return list.size() >= 1;
    }

    public static void performAction(Context context, BaseActivity activity) {
        PendingIntent pendingIntent = PendingIntent.getService(context, 0,
                new Intent(activity.getString(R.string.service_intent)))
               .getIntent(null);
        try {
            context.startService(new Intent(activity.getString(R.string
                   .service_intent_name)));
        } catch (Exception e) {
        }
    }
}

Step 5: Display Ads

After initializing AdMob, use the AdMob object's LoadAd() method to load an ad:

1. In the PokerActivity.java file, add a method to load the ad:

@SuppressLint("CheckResult")
public void loadAd(Context context) {
    this.adMob = new AdMob(this);
    AdRequest adRequest = new AdRequest.Builder().build();
    this.adMob.LoadingAd(adRequest);

    this.adMob.loadAd(adRequest);
    this.adMob.getAdView().setOnParentChangedListener(new OnAdLoadedListener());
}

Step 7: Display the Result

Finally, display the ad in the PokerActivity.class:

1. Add an AdView to the Activity's layout:

<LinearLayout
            android:layout_width="match_parent"
            android:layout_height="match_parent"
            android:orientation="vertical">

        <TextView
            android:id="@+id/information"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"/>

        <Button
            android:id="@+id/button"
            android:layout_width="match_parent"
            android:layout_height="wrap_content"

            android:text="Continue"/>

        <com.google.android.gms.ads.AdView
            android:id="@+id/adView"
            android:layout_width="wrap_content"
            android:layout_height="wrap_content"
            app:adSize="SmartBanner"
            app:adUnitId="add_your_ad_unit_ID_here"/>

    </LinearLayout>

Bonus Step: Implement Ad Handling

To handle ad results, you can use listeners:

1. Create a listener class:

public class OnAdLoadedListener implements AdSizeChangedListener {
    @Override
    public void sizeChanged(int width, int height) {
        setAdSize(width, height);
    }

    private void setAdSize(int width, int height) {
        // set up the ad size here based on the size
        // you can set image size or other sizes or whatever
    }
}

public class OnAdCompleteListener implements AdCompleteListener {
    @Override
    public void adLoaded() {

    }

    @Override
    public void error(String error) {

    }
}

Finally, we have created an Android poker game with in-app advertisements using AdMob and handled GDPR compliance, all within Android Studio!

This step-by-step tutorial has equipped you with the necessary steps to create a simple yet functional poker game for Android devices, while also enabling AdMob for revenue generation and complying with GDPR requirements.
