Objectives▀ Learn about:

The various ad companies

Ad measurements

AdViews

Define an ad using XML and java


Ad Companies▀ AdMob, Inmobi, Mopub,

Jumptap, Tapit, Smaato, Mobfox, AdSense

▀ They provide code that you add to your app

▀ Their code figures out size of ad to display based on the device


Measurements▀ CTR – click through rate

% of people who click on an ad► If the ad is displayed 100 times and is

clicked twice, the ctr is 2% or .02

▀ CPC – cost per click

How much advertiser will pay you for each click

►47 cents for each click through


Measurements▀ eCPM – effective cost per thousand

ad views (impressions)

How much you should make for a thousand ads being displayed

Need to multiply CPC (.47) by 1000 by CTR (.02)

► .47 * 1000 * .02 = $9.40

▀ Ad companies track all these measurements (and report them to you)


Admob provides reports


Notice reported stats


Detailed stats


My sad, unpopular app


Measurements▀ Most of the ad companies won’t let

you post these numbers

▀ Also, if they see unusual numbers:

A CTR of 57%

Clicks are done by a small % of users or locations

►They may shut down your app

• People have their friends, relatives, and neighbors download app and click ads


Going to use AdMob (owned by Google) http://www.google.com/ads/admob/


Sign up using your google account


If you are at the same computer that you created the account on they will know who you are!

If so, fill in the password


Specify info for an Admob account then click Continue


Scroll down, accept Terms, click Submit


Click Add Your First App


Specify tax and payment info, the click Submit


Click Sites and Apps then Android App


Fill in app info and click Continue


Go to https://apps.admob.com/#home click Monetize new app


Specify Project name and Android


Specify Ad type and give it a name


You can change some ad formatting


You need the add unit ID and you can have them info email to you


Specify email address to send to


The Ad unit ID that you will need to get ads


Go back to Home, scroll down, and the project(s) should be displayed


Creating From Scratch▀ Must create a new project

(AdProj) with a min target of 3.2, package (my.ad.com), activity (AdProjActivity), and layout (main) Example will be 4.X

▀ Need to: Add a reference to the Google play

services library

Modify the Manifest


Must import google-play-services_lib into the workspace (Should already be there from MapProj but if not…)

File, Import, expand the Android folder and select Existing Android Code Into WorkSpace, then click Next


Click the Browse button then navigate to the sdk/extras/google/google_play_services/libproject/google-

play-services_lib, click OK then Finish


Click Android

Right click AdProj and select Properties


Scroll down, click Add, then select the library and click OK

•c


Setup▀ Manifest have:

The following meta tag in the application element

The following activity defined

<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"/>


Setup The following permissions

outside the application tags

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


Defining an Ad▀ Use an AdView component

▀ Two ways to define an AdView

With xml in the layout

With java in the activity

▀ Will define an AdView component in xml


<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"> <com.google.android.gms.ads.AdView android:id="@+id/adView" android:layout_width="wrap_content" android:layout_height="wrap_content" ads:adUnitId="ca-app-pub-6333216089167186/1679833953" ads:adSize="BANNER"/> <TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /></LinearLayout>

Don’t forget to substitute your Ad Unit ID in the adUnitId parameter

main.xml


AdProjActivity.java▀ Need to import

▀ Need an AdView variable and object in onCreate then After setContentView, create an

AdRequest and add a test device

Load ad into adView

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

// Look up the AdView as a resource and load a request. AdView adView = (AdView)this.findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder() .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .addTestDevice("abc") .build(); adView.loadAd(adRequest);


AdProjActivity.java▀ You will get a test ad

Google doesn't want you to download real ads while testing

▀ To get a real add

// Look up the AdView as a resource and load a request. AdView adView = (AdView)this.findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder() //.addTestDevice(AdRequest.DEVICE_ID_EMULATOR) //.addTestDevice("abc") .build(); adView.loadAd(adRequest);


AdProjActivity.java

▀ Have to run to get a real TestDevice number

▀ Find in logcat


AdProjActivity.java

▀ Substitute for abc

// Look up the AdView as a resource and load a request. AdView adView = (AdView)this.findViewById(R.id.adView); AdRequest adRequest = new AdRequest.Builder(). .addTestDevice(AdRequest.DEVICE_ID_EMULATOR) .addTestDevice("B3EEABB8EE11C2BE770B684D95219ECB") .build(); adView.loadAd(adRequest);


ads:adSize="SMART_BANNER"


ads:adSize="MEDIUM_RECTANGLE"


Other Types of Ad

Interstitial Ads

Full screen ads with a close button

More expensive, therefore there are often display limits


Go back to AdMob and add an Interstatial add to the app


Specify timeout and ad name


Interstitial Need class level variables

In onCreate, create an InterstitialAd object, set the Ad Unit ID, create the AdRequest and load the ad

private InterstitialAd interstitial;private static final String AD_UNIT_ID = "ca-app-pub-6333216089167186/1679833953";

interstitial = new InterstitialAd(this);interstitial.setAdUnitId(AD_UNIT_ID);

// Create ad request.AdRequest adRequest = new AdRequest.Builder().build();

// Begin loading the interstitialinterstitial.loadAd(adRequest);


Interstitial Ads Can take a while to load

If you try to display before loaded will get an error

So we will put a button on the screen and show the ad after the button is touched


<?xml version="1.0" encoding="utf-8"?><LinearLayout xmlns:android="http://schemas.android.com/apk/res/android" xmlns:ads="http://schemas.android.com/apk/res-auto" android:orientation="vertical" android:layout_width="match_parent" android:layout_height="match_parent"><TextView android:layout_width="wrap_content" android:layout_height="wrap_content" android:text="@string/hello_world" /> <LinearLayout android:layout_width="fill_parent" android:layout_height="wrap_content" android:orientation="horizontal" android:layout_marginLeft="100px"> <Button android:id="@+id/Btn" android:layout_width="wrap_content" android:layout_height="wrap_content" android:onClick="doClick"

android:text="Show Ad" /> </LinearLayout></LinearLayout>

main.xml


doClick in AdProjActivity

Time to test

import android.view.View; : : :public void doClick(View arg0) {

interstitial.show();}


Check in logcat that ad has loaded


Click Show Ad


AdListeners In java, Activity can implement

the AdListener interface

Then tie the ad listener to the adView

adView.setAdListener(this);


AdListeners Activity can implement onAdxxx

methods that are called when ad is: Successfully and unsuccessfully

received onAdLoaded, onAdFailedToLoad

When ad is overlaid on the screen onAdOpened

Ad dismissed and returning to app onAdClosed

When ad clicked onAdLeftApplication


AdListeners So instead of having a button to

display the ad

Create onAdLoaded method and have it display the ad

And if ad doesn't load

Create onFailedToLoad method to retry to load the ad
