自己挣点油钱__AdMob：在android应用中嵌入广告的方案

AdMob：The Mobile Advertising Platform
Industry-leading mobile advertising and monetization solutions from the trusted
name in mobile advertising.


AdMob是一个比较成熟的移动平台 广告 商，其为Android 和 iPhone提供了非常方便的集成JAR包，使得开发 者可以在自己的应用 中很方便的嵌入其提供的广告 ，进而按照广告 展 示和点击次数付广告 费。这里用个例子 给大家演示下如何在自己的应用中集成AdMob的广告 功能 。

0、准备工作
去http://www.admob.com/ 注 册一个帐号，然后添加一个“Add Mobile Site”，输入相关信息后，提交完成，进入AD代码 获取 界面 ，其提供了PHP，Rails等等类型的代码，同时 提供了Android平台使用的JAR，我们就来演示这个。

1、下载 JAR包
其为android 平台提供了JAR包，然后将JAR添 加到你的项目 组，按照如下步骤


Go to the Properties of your project (right-click on your project from the Package Explorer tab and select Properties)
Select "Java Build Path" from left panel
Select "Libraries" tab from the main window
Click on "Add JARs..."
Select the JAR copied to the libs directory
Click "OK" to add the SDK to your android project


2、编辑AndroidManifest.xml
Your AdMob publisher ID was given to you when creating your publisher account on www.admob.com before downloading this code. It is a 15-character code like a14a48e3387c5ce . Just before the closing </application> tag add a line to set your publisher ID:
                <!-- The application's publisher ID assigned by AdMob -->
                <meta-data android :value="YOUR_ID_HERE" android :name="ADMOB_PUBLISHER_ID" />
        </application>

Set any permissions not already included just before the closing </manifest> tag:
                <!-- AdMob SDK permissions -->
                <uses-permission android :name="android .permission.INTERNET" />
                <uses-permission android :name="android .permission.READ_PHONE_STATE" />
                <uses-permission android :name="android .permission.ACCESS_COARSE_LOCATION" />
        </manifest>       


Only the INTERNET permission is required. Setting READ_PHONE_STATE is highly recommended because it identifies the user letting a greater variety of more relevant ads be chosen. Finally setting ACCESS_COARSE_LOCATION (and/or ACCESS_FINE_LOCATION) will let geo-targeted ads be shown.

3、添加attrs.xml
The attrs.xml file specifies custom AdView attributes in XML layout files. If your application does not already have an/res/values/attrs.xml file then create one and copy-and-paste the following into it. If you do have that file then just add the declare-styleable element:      
        <?xml version="1.0" encoding="utf-8"?>
        <resources>
                <declare-styleable name="com.admob.android .ads.AdView">
                        <attr name="testing" format="boolean" />
                        <attr name="backgroundColor" format="color" />
                        <attr name="textColor" format="color" />
                        <attr name="keywords" format="string" />
                        <attr name="refreshInterval" format="integer" />
                        <attr name="isGoneWithoutAd" format="boolean" />
                </declare-styleable>
        </resources>

4、Placing an AdView in a Layout
AdView widgets can be put into any XML layout now. The first step is to reference attrs.xml in your layout element by adding an xmlns line that includes your package name specified in AndroidManifest.xml:
<?xml version="1.0" encoding="utf-8"?>
<LinearLayout
    xmlns:android ="http://schemas.android .com/apk/res/android "
xmlns:admobsdk ="http://schemas.android .com/apk/res/com.eoe android .demo.Adadmob"
androidrientation="vertical"
android :layout_width="fill_parent"
android :layout_height="fill_parent">

<TextView
android :layout_width="fill_parent"
android :layout_height="wrap_content"
android :textSize="24px"
android :paddingBottom="10px"
android :layout_gravity="center"
android :text="eoeAndroid  - 最棒的Android开发社区 " />
<TextView
android :layout_width="fill_parent"
android :layout_height="wrap_content"
android :textSize="18px"
android :paddingBottom="10px"
android :layout_gravity="center"
android :text="eoeAndroid.com 立足于Android开发者 ，营造一个乐于分享、共同进步的开发者社区." />
<com.admob.android .ads.AdView android :id="@+id/ad"
android :layout_width="fill_parent"
android :layout_height="wrap_content"
admobsdk:backgroundColor="#000000"
admobsdk:textColor="#FFFFFF"
admobsdk:keywords="Android application"
admobsdk:refreshInterval="60"
/>
</LinearLayout>
