AdMob Advertising

Introduction

- Advertisements are served into an AdView
- You get paid for click throughs on the banner ads. The amount depends on what ads you are served.
- Advertisements can be focussed to demographics
- Download the AdMob library from the AdMob download site.
Using an AdView
- Add an activity in the manifest
```
<activity 
    android:name="com.google.ads.AdActivity"
    android:configChanges="keyboard|keyboardHidden|orientation|
screenLayout|uiMode|screenSize|smallestScreenSize">
</activity>
```
- Specify permissions in the manifest
  <uses-permission android:name="android.permission.INTERNET"/> <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"/>
- Set the target SDK in Eclipse to at least 13 (even if the minSdkVersion is lower in the manifest.
- Add the AdMob .jar as an external JAR library, in the app properties, and use order and export to ensure it is included when compiling.
- Insert an AdView somewhere in your UI.
  - Register the app with AdMob to get a unit/publisher id, and put that in a ads:adUnitId tag.
  - Set the ad size with ads:adSize, e.g., BANNER is common for phones.
  - Specify the test devices with ads:testDevices, probably including at least TEST_EMULATOR
  - To autoload an advert when the app starts, specify ads:loadAdOnCreate="true".
- Loading ads
