Integrating Google AdMob with Banner in Android Applications

Overview :

AdMob brings together best-in-class technology in a single platform, so you can gain insights about your users, drive more in-app purchases, and maximize your ad revenue. No longer will you have to rely on a combination of tools or use precious development resources to build your own solution.

Step 1 :

First we add an account in AdMob publisher and Identify your publisher ID on the top right of your dashboard. Click here to sign up the AdMob publisher.

Step 2 :

Create a new project in Eclipse File ⇒ New ⇒ Android Application Project. Fill in the details and name your project AdmobProject.

Step 3 :

Here is a complete example of MainActivity.java

package com.sampleadmob;

import android.app.Activity;

import android.os.Bundle;

import com.google.android.gms.ads.AdListener;

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

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

import com.google.android.gms.ads.InterstitialAd;

public class MainActivity extends Activity {

private InterstitialAd interstitial;

@Override

protected void onCreate(Bundle savedInstanceState) {

super.onCreate(savedInstanceState);

setContentView(R.layout.activity_main);

interstitial = new InterstitialAd(MainActivity.this);

// Insert the Ad Unit ID

interstitial.setAdUnitId("ca-app-pub-xxxxxxxxxxxx/xxxxxxxxxx");

AdView adView = (AdView) this.findViewById(R.id.adView);

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

adView.loadAd(adRequest);

interstitial.loadAd(adRequest);

interstitial.setAdListener(new AdListener() {

public void onAdLoaded() {

displayAd();

}

});

}

public void displayAd() {

// If Ads are loaded, show Interstitial else show nothing.

if (interstitial.isLoaded()) {

interstitial.show();

}

}

}

Step 4 :

In activity_main.xml we declare this

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"

xmlns:tools="http://schemas.android.com/tools"

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

android:layout_width="match_parent"

android:layout_height="match_parent"

android:paddingBottom="@dimen/activity_vertical_margin"

android:paddingLeft="@dimen/activity_horizontal_margin"

android:paddingRight="@dimen/activity_horizontal_margin"

android:paddingTop="@dimen/activity_vertical_margin"

tools:context="com.example.sampleadmob.MainActivity" >

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

android:id="@+id/adView"

android:layout_width="wrap_content"

android:layout_height="wrap_content"

ads:adSize="BANNER"

// Insert the Ad Unit ID

ads:adUnitId="ca-app-pub-xxxxxxxxxxxxx/xxxxxxxx" />

</RelativeLayout>

Step 5 :

In Android manifest file we declare permissions to allow the internet connection and network state and declare activity for Google play services.

Declare Google services activity :

<meta-data

android:name="com.google.android.gms.version"

android:value="@integer/google_play_services_version" />

<activity

android:name="com.google.android.gms.ads.AdActivity" android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize" >

</activity>

Internet and network state permission :

<uses-permission android:name="android.permission.INTERNET" />

<uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
