Introduction

AWallZ is a popular native Android HD Wallpaper app that allows users to browse and download high-definition wallpapers. With its clean and intuitive interface, AWallZ has gained a significant following among Android users. In this tutorial, we will guide you on how to integrate AWallZ with a WordPress back-end, AdMob, and Firebase Cloud Messaging (FCM) push notifications.

Prerequisites

Before we begin, please ensure you have the following:

1. A Windows or macOS machine with a stable internet connection.
2. Android Studio installed on your machine.
3. WordPress installed on your server or local machine.
4. AdMob account and FCM project created.
5. Basic knowledge of Android development, WordPress, and Firebase.

Step 1: Set up the AWallZ App

1. Clone the AWallZ GitHub repository to your local machine using Git.
2. Open the cloned project in Android Studio.
3. Create a new Android Virtual Device (AVD) or use an existing one.
4. Run the app on the AVD or your physical Android device.

Step 2: Set up WordPress Back-end

1. Create a new WordPress site on your server or local machine.
2. Install and activate the following plugins:
   • WP REST API
   • WP Fusion
   • Jetpack (optional)
3. Create a new page and add the following shortcode: [awallz-widgets]
4. Save the page and navigate to it in your WordPress site.

Step 3: Integrate AWallZ with WordPress

1. In the AWallZ app, navigate to the res/values/strings.xml file.

2. Add the following lines to the file:

   <string name="api_url">http://your-wordpress-site.com/wp-json/wp/v2</string>
   <string name="api_key">your-wordpress-api-key</string>

   Replace http://your-wordpress-site.com/wp-json/wp/v2 with your WordPress site's API URL and your-wordpress-api-key with your WordPress API key.

3. In the AWallZ app, navigate to the app/src/main/java/com/example/awallz/WallpaperAdapter.java file.

4. Modify the getWallpapers() method to fetch wallpapers from your WordPress site's API:

   public List<Wallpaper> getWallpapers() {
   Retrofit retrofit = new Retrofit.Builder()
          .baseUrl(getApiUrl())
          .addConverterFactory(GsonConverterFactory.create())
          .build();
   
   WallpaperService service = retrofit.create(WallpaperService.class);
   
   Call<List<Wallpaper>> call = service.getWallpapers();
   Response<List<Wallpaper>> response = call.execute();
   
   return response.body();
   }

5. In the AWallZ app, navigate to the app/src/main/java/com/example/awallz/MainActivity.java file.

6. Modify the onCreate() method to fetch wallpapers from your WordPress site's API:

   protected void onCreate(Bundle savedInstanceState) {
   super.onCreate(savedInstanceState);
   setContentView(R.layout.activity_main);
   
   WallpaperAdapter adapter = new WallpaperAdapter(getSupportFragmentManager());
   RecyclerView recyclerView = findViewById(R.id.recycler_view);
   recyclerView.setAdapter(adapter);
   
   adapter.setWallpapers(getWallpapers());
   }

   Step 4: Integrate AdMob

7. Create a new AdMob account and enable the Google Mobile Ads SDK.
8. In the AWallZ app, navigate to the app/src/main/java/com/example/awallz/MainActivity.java file.
9. Add the following code to the onCreate() method:

   
   MobileAds.initialize(this, new OnInitializationCompleteListener() {
   @Override
   public void onInitializationComplete() {
       // AdMob initialization complete
   }
   });

mAdView = findViewById(R.id.ad_view); AdRequest adRequest = new AdRequest.Builder().build(); mAdView.loadAd(adRequest);

4. In the `res/layout/activity_main.xml` file, add the following code:
```xml
<com.google.android.gms.ads.AdView
    xmlns:ads="http://schemas.android.com/apk/res-auto"
    android:id="@+id/ad_view"
    android:layout_width="wrap_content"
    android:layout_height="wrap_content"
    ads:adSize="BANNER"
    ads:adUnitId="your-admob-ad-unit-id" />

Replace your-admob-ad-unit-id with your AdMob ad unit ID.

Step 5: Integrate FCM Push Notification

1. Create a new Firebase project and enable the Firebase Cloud Messaging (FCM) API.
2. In the AWallZ app, navigate to the app/src/main/java/com/example/awallz/MainActivity.java file.
3. Add the following code to the onCreate() method:

   FirebaseMessaging.getInstance().subscribeToTopic("awallz");

4. In the res/xml/google-services.xml file, add the following code:

   <?xml version="1.0" encoding="utf-8"?>
   <google-services
   xmlns:tools="http://schemas.android.com/tools"
   tools:targetApi="19">
   <resources>
       <string name="firebase_cloud_messaging_sender_id">your-fcm-sender-id</string>
   </resources>
   </google-services>

   Replace your-fcm-sender-id with your FCM sender ID.

Step 6: Test the App

1. Run the app on your Android device or emulator.
2. Verify that the app fetches wallpapers from your WordPress site's API.
3. Verify that the app displays AdMob ads.
4. Verify that the app receives FCM push notifications.

Conclusion

In this tutorial, we have integrated the AWallZ app with a WordPress back-end, AdMob, and Firebase Cloud Messaging (FCM) push notifications. With these integrations, you can now create a native Android app that fetches wallpapers from your WordPress site's API, displays AdMob ads, and receives FCM push notifications.
