我正在使用最新版本的Eclipse，ADT和最新的Android SDK。例如，如果我尝试在简单的HelloWorld Android项目Google
Play功能中使用某些功能，

int res = GooglePlayServicesUtil.isGooglePlayServicesAvailable(this);

该应用程序崩溃

我真的不明白为什么它不起作用。我已经通过File> Import> [从lib源复制]添加了。我尝试使用Android
5.1.1和GoogleAPI。我将google-play-service_lib作为lib项目链接到我的helloworld项目。之后，我在“属性”>“
Java构建路径”>“库”>“添加罐子”（lib文件）中添加了。订单和导出复选框也被选中。在Android清单中，我添加了

 <meta-data android:name="com.google.android.gms.version"
        android:value="@integer/google_play_services_version" />

简而言之，我直接做了官方手册中写的内容

我清理了一下，然后重新启动，等等……但是没有用。天哪？是什么原因？我在不同的设备和不同的机器上进行了测试。同样的愚蠢错误！
