Google Admob with Banner and Interstitial Ads in Android Apps |

This Blog is in continuation with our previous blog “Beginner’s Guide to AdMob – a Portmanteau for “Advertising on Mobile” where we talked all about AdMob and how to monetize your App with Ads. Here we will go a step forward and talk about how to actually write code for the App to create AdMob in it.

Below we will be discussing the code: AdMob

Create a Sample Application for Two Types of AdMob about Banner Ad and Interstitial Ad. First we will talk about Banner Ad.

Get Skilled in Android Development

Banner Ad App:

First of all add the code for Google Ad services in build.gradle file In dependencies:

compile 'com.google.android.gms:play-services:7.0.0'

2. In the manifest file i.e AndroidManifest.xml add below code

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.android.gms.example.bannerexample" >
    <!-- Include required permissions for Google Mobile Ads to run-->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <!--This meta-data tag is required to use Google Play Services.-->
        <meta-data android:name="com.google.android.gms.version"/>
        <activity
            android:name=".MyActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!--Include the AdActivity configChanges and theme. -->
        <activity android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />
    </application>
</manifest>

3. Add your banner Ad unit ID to string.xml file:

<!-- This is an ad unit ID for a test ad. Replace with your own banner ad unit id. -->
    <string name="banner_ad_uncait_id">-app-pub-3940256099942544/6300978111</string>

Note: This banner ID key is for my Ad. Since you have already learn how to generate banner ID key, create a new Ad ID for your app.

4. Add below code to MainActivity.java

package com.google.android.gms.example.bannerexample;
import android.os.Bundle;
import android.support.v7.app.ActionBarActivity;
import android.view.Menu;
import android.view.MenuItem;
import android.webkit.WebView;
import com.google.android.gms.ads.AdRequest;
import com.google.android.gms.ads.AdView;
public class MyActivity extends AppCompatActivity {
    private AdView mAdView;
    private WebView webview;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
         mAdView = (AdView) findViewById(R.id.ad_view);
        AdRequest adRequest = new AdRequest.Builder()
                .addTestDevice(AdRequest.DEVICE_ID_EMULATOR)
                .build();
        mAdView.loadAd(adRequest);
        webview = (WebView) findViewById(R.id.webView);
        webview.getSettings().setJavaScriptEnabled(true);
        webview.loadUrl(" https://acadgild.com/blog/category/android/");
    }
    @Override
    public boolean onCreateOptionsMenu(Menu menu) {
        getMenuInflater().inflate(R.menu.my, menu);
        return true;
    }
    @Override
    public boolean onOptionsItemSelected(MenuItem item) {
        int id = item.getItemId();
        if (id == R.id.action_settings) {
            return true;
        }
        return super.onOptionsItemSelected(item);
    }
    @Override
    public void onPause() {
        if (mAdView != null) {
            mAdView.pause();
        }
        super.onPause();
    }
    @Override
    public void onResume() {
        super.onResume();
        if (mAdView != null) {
            mAdView.resume();
        }
    }
    @Override
    public void onDestroy() {
        if (mAdView != null) {
            mAdView.destroy();
        }
        super.onDestroy();
    }
}

5. Add this code to design your ad in “activity_main.xml” file

<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:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    android:layout_marginTop="@dimen/activity_vertical_margin"
    tools:context=".MyActivity"
    tools:ignore="MergeRootFrame">
    <com.google.android.gms.ads.AdView
        android:id="@+id/ad_view"
        android:layout_width="match_parent"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_alignParentBottom="true"
        ads:adSize="BANNER"
        ads:adUnitId="@string/banner_ad_unit_id" />
    <WebView
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:id="@+id/webView"
        android:layout_alignParentTop="true"
        android:layout_alignParentLeft="true"
        android:layout_alignParentStart="true"
        android:layout_above="@+id/ad_view"
        android:layout_alignParentRight="true"
        android:layout_alignParentEnd="true" />
</RelativeLayout>

Run the code and you will see the output as shown in figure below:

With this we have successfully learnt how to create and display Ad at the bottom of the page. Now we will see how to create an Interstitial Ad in the App.

Interstitial Ad App

1. First of all add the code for Google Ad services in build.gradle file In dependencies

compile 'com.google.android.gms:play-services:7.0.0'

2. In the manifest file i.e AndroidManifest.xml add below code

<?xml version="1.0" encoding="utf-8"?>
<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.google.android.gms.example.interstitialexample" >
    <!-- Include required permissions for Google Mobile Ads to run. -->
    <uses-permission android:name="android.permission.INTERNET"/>
    <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
    <application
        android:allowBackup="true"
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <!--This meta-data tag is required to use Google Play Services. -->
        <meta-data android:name="com.google.android.gms.version" android:value="@integer/google_play_services_version"/>
        <activity
            android:name=".MyActivity"
            android:label="@string/app_name" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        <!--Include the AdActivity configChanges and theme. -->
        <activity android:name="com.google.android.gms.ads.AdActivity"
            android:configChanges="keyboard|keyboardHidden|orientation|screenLayout|uiMode|screenSize|smallestScreenSize"
            android:theme="@android:style/Theme.Translucent" />
    </application>
</manifest>

3. Add this code to design your ad in “activity_main.xml” file

<RelativeLayout xmlns:android="http://schemas.android.com/apk/res/android"
    xmlns:tools="http://schemas.android.com/tools"
    android:id="@+id/container"
    android:layout_width="match_parent"
    android:layout_height="match_parent"
    tools:context=".MyActivity"
    tools:ignore="MergeRootFrame">
    <TextView
        android:id="@+id/game_title"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_marginTop="50dp"
        android:text="@string/impossible_game"
        android:textAppearance="?android:attr/textAppearanceLarge" />
    <TextView
        android:id="@+id/timer"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_below="@+id/game_title"
        android:layout_centerHorizontal="true"
        android:textAppearance="?android:attr/textAppearanceLarge" />
    <Button
        android:id="@+id/retry_button"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:layout_centerHorizontal="true"
        android:layout_centerVertical="true"
        android:text="Retry" />
</RelativeLayout>

4. Add below code to MainActivity.java

    private InterstitialAd mInterstitialAd;
    private CountDownTimer mCountDownTimer;
    private Button mRetryButton;
    private boolean mGameIsInProgress;
    private long mTimerMilliseconds;
    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_my);
        // Create the InterstitialAd and set the adUnitId.
        mInterstitialAd = new InterstitialAd(this);
        // Defined in res/values/strings.xml
        mInterstitialAd.setAdUnitId(getString(R.string.ad_unit_id));
        mInterstitialAd.setAdListener(new AdListener() {
            @Override
            public void onAdClosed() {
                startGame();
            }
        });
        mRetryButton = ((Button) findViewById(R.id.retry_button));
        mRetryButton.setVisibility(View.INVISIBLE);
        mRetryButton.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                showInterstitial();
            }
        });
        startGame();
    }
    private void createTimer(final long milliseconds) {
        if (mCountDownTimer != null) {
            mCountDownTimer.cancel();
        }
        final TextView textView = ((TextView) findViewById(R.id.timer));
        mCountDownTimer = new CountDownTimer(milliseconds, 50) {
            @Override
            public void onTick(long millisUnitFinished) {
                mTimerMilliseconds = millisUnitFinished;
                textView.setText("seconds remaining: " + ((millisUnitFinished / 1000) + 1));
            }
            @Override
            public void onFinish() {
                mGameIsInProgress = false;
                textView.setText("done!");
