I tried for 3 days to implement it, and I was just able to make it work on one of the menus and the loading screen. I also want to ad interstitial ads when you add a sticker pack to WhatsApp, but I don't know how because it always crashes for me.

Literally, all that I have got working was made by trial and error. I don't know what to do because I have tried many things, but they haven't worked.

The code: https://github.com/WhatsApp/stickers
How I want it to look like and how I want ads to appear (i want ads to work like how they do in this app): https://play.google.com/store/apps/details?id=com.easycodes.animes

It is quite hard to help you without more details, but i will tell you how i did it.

First, follow the instructions Admob Implementation

1- Download the dependencies:

implementation 'com.google.android.gms:play-services-ads:17.1.1'

2 - In AndroidManifest.xml paste this code:

<meta-data

            android:name="com.google.android.gms.ads.APPLICATION_ID"

            android:value="[ADMOB_APP_ID]"/>

Where ADMOB_APP_ID is the id of your app that you set up on your admob account.
You should save that on strings.xml by the name of ADMOB_APP_ID.

It should look something like this:

android:value="@string/APPLICATION_ID" 

** 3 - Now that you've done that, do the following:**

Paste this on layous/stickers_pack_details.xml:

<com.google.android.gms.ads.AdView

        xmlns:ads="http://schemas.android.com/apk/res-auto"

        android:id="@+id/adView"

        android:layout_width="wrap_content"

        android:layout_height="wrap_content"

        android:layout_marginLeft="8dp"

        ads:adSize="BANNER"

        ads:adUnitId="@string/ADD_UNIT_ID"

        android:layout_marginStart="16dp">

    </com.google.android.gms.ads.AdView>

Then, go to java/class/StickersPackActivity, and paste this:

 MobileAds.initialize(this, getString(R.string.APPLICATION_ID));



        mAdView = findViewById(R.id.adView);

        AdRequest adRequest = new AdRequest.Builder().build();

        mAdView.loadAd(adRequest);

I won't go into details , you have to do some more stuff(for example, mAdView needs to be declared at the top, and your APPLICATION_ID needs to be declared on strings.xml in order to work)

It should look something like this(on strings.xml):

<string name="APPLICATION_ID">HERE_GOES_YOUR_APP_ID</string>

    <string name="ADD_UNIT_ID">HERE_GOES_YOUR_ADD_UNIT_ID</string>

Now, you should be able to see your ads on your stickers app.
