Admob Banner Ads in Android – Admob Ads v-20.2.0

Hello Guys, In this tutorial, we will see how to implement Admob Banner Ads in Android. So Open Android Studio and create a project. Now follow the below steps

Integrate Admob SDK into yourApp

In app-level build.gradle under dependencies Section

dependencies {


  implementation 'com.google.android.gms:play-services-ads:20.2.0'


}

In you AndroidManifest.xml File

<manifest>
    <application>
        
        <meta-data
            android:name="com.google.android.gms.ads.APPLICATION_ID"
            android:value="ca-app-pub-3940256099942544~3347511713"/>
    </application>
</manifest>

Initialize the Mobile Ads SDK

Before loading ads, have your app initialize the Mobile Ads SDK by calling MobileAds.initialize() which initializes the SDK and calls back a completion listener once initialization is complete (or after a 30-second timeout). This needs to be done only once, ideally at the app launch.

In your MainActivity after setContentView place this code to Initialize Admob Ads SDK

MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });

Now we write Code for Banner Ads

In activity_main.xml file, we design a banner ad display

activity_main.xml

<?xml version="1.0" encoding="utf-8"?>
<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:app="http://schemas.android.com/apk/res-auto"
    xmlns:tools="http://schemas.android.com/tools"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MainActivity">

    <TextView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:text="We Display Admob Banner Here"
        android:layout_centerInParent="true"
        android:textColor="@color/black"
        android:textSize="25sp"/>

    <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_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="ca-app-pub-3940256099942544/6300978111">
    </com.google.android.gms.ads.AdView>

</RelativeLayout>

Note: Always Use Test Ads

You Can also set ad unit and ad size Programmatically. Check Documentation here

Now Let’s Code MainActivity.java

MainActivity.java

package com.example.admobsampleapp;

import androidx.appcompat.app.AppCompatActivity;

import android.os.Bundle;

import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
import com.google.android.gms.ads.MobileAds;
import com.google.android.gms.ads.initialization.InitializationStatus;
import com.google.android.gms.ads.initialization.OnInitializationCompleteListener;

public class MainActivity extends AppCompatActivity {

    private AdView mAdView;

    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

        MobileAds.initialize(this, new OnInitializationCompleteListener() {
            @Override
            public void onInitializationComplete(InitializationStatus initializationStatus) {
            }
        });

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

If you want to Listen to AdEvents then add AdListener to your Code

mAdView.setAdListener(new AdListener() {
    @Override
    public void onAdLoaded() {
        // Code to be executed when an ad finishes loading.
    }

    @Override
    public void onAdFailedToLoad(LoadAdError adError) {
        // Code to be executed when an ad request fails.
    }

    @Override
    public void onAdOpened() {
        // Code to be executed when an ad opens an overlay that
        // covers the screen.
    }

    @Override
    public void onAdClicked() {
        // Code to be executed when the user clicks on an ad.
    }

    @Override
    public void onAdClosed() {
        // Code to be executed when the user is about to return
        // to the app after tapping on an ad.
    }
});

In the next Admob Ads tutorial, we will try to implement Admob Interstitial Ads. Until then Check our Android Tutorials here.
