The following classes could not be instantiated: - com.google.android.gms.ads.AdView (Open Class, Show Error Log) : AdMob
我已经按照开发人员admob网站上的文档中给出的步骤（按原样复制并粘贴）。 并在eclipse ADT中实现了他们的例子。它仍无法正常工作......应用程序意外停止。

答案 0 :(得分：3)
您的代码应该有效，没有问题。我认为，您没有将您的项目与Google提供的库集成。这篇文章可能会对你有所帮助：
https://developers.google.com/admob/android/eclipse#include_the_google_play_services_library
请彻底按照步骤操作。
答案 1 :(得分：2)
您是否已将Google Play服务lib导入为项目？
将google-play-services_lib导入为项目非常重要：
Select File > Import > Android > Existing Android Code Into Workspace并单击“下一步”。
选择浏览...，输入
[android-sdk-folder]/extras/google/google_play_services/libproject/google-play-services_lib，然后单击“完成”。
（参见“示例代码”下的https://developers.google.com/maps/documentation/android/intro）
然后按照链接答案中的说明进行操作：
导入“google-play-services_lib”项目的实际来源，并将其链接为＆gt; Android库。
通过Project执行此操作 - ＆gt;属性 - ＆gt; Android - ＆gt;图书馆，添加 - ＆gt; google-play-services_lib（您可以右键单击您的项目和 选择属性，然后选择Android）。
不要通过项目的“Java Build Path”将其添加为依赖项目，这对我来说无效。
答案 2 :(得分：1)
从您的网站获取自己的Google Play服务 ADT-束 - 窗口x86-20130514 \ SDK \演员\谷歌。这会奏效 挑衅。
答案 3 :(得分：1)
ShellCommandUnresponsiveException需要太长时间才能发送输出。
该命令实际上可能没有响应，它只是花了太多时间没有向控制台输出任何东西。 所以这个问题与你的代码无关。
答案 4 :(得分：0)
修改（答案）：
谢谢你的回答。我很感激。
我开始了解实际问题，Eclipse ADT没有更新，因此错误在那里，但是在更新之后，它仍然无法工作，因此我切换到Android Studio，代码现在按预期工作。< / p>
谢谢大家
