Google Play 服务 9.2.0 (Admob) 的 NoClassDefFoundError

Question

我在 Eclipse 中处理一个遗留项目，需要更新 Google Play 服务，特别是 Analytics 和 Admob。

在尝试通过从 Android SDK /extras/ 文件夹中复制 JAR 文件来获取 9.2.0 时，我发现由于 Google 切换到支持 Android Studio 的 AAR 文件，这不再可能。

我发现this GitHub project 将所有 Google Play 服务 AAR 模块扩展为单独的 Android 项目。我已经下载并导入了适用于 Analytics 和 Admob 的项目，如此处所示 (https://github.com/dandar3/android-google-play-services-README)。

我的项目成功编译，没有错误，因此所有类都可以正确访问和链接。

但是，在运行 Android 6.0.1 的 Nexus 5 上启动时，我在启动时经常收到此消息：

第 102 行指的是这个，在启动时出现：

AdRequest adRequest = new AdRequest.Builder().build();

根据我的研究，我所看到的只是对影响 Gingerbread 设备的（旧）错误的引用，但我认为这不适用于这里。

编辑：我的 build.gradle 文件按要求。不确定是否相关，因为我没有使用它来将依赖项链接到 Google Play 服务，但无论如何都是这样：

所以第二天我将 Android 库“play-services-basement”作为依赖项添加到我的项目中，一切正常。没有意识到我需要将它作为依赖项直接添加到我自己的项目中，因为 admob/analytics 项目也隐式添加了它。
