Java Google Play Services 9.2.0（Admob）的NoClassDefFoundError

我正在Eclipse中从事一个遗留项目，需要更新Google Play服务，特别是Analytics和Admob

在尝试通过从Android SDK

/extras/

文件夹复制JAR文件来获得9.2.0旧方法时，我发现这不再可能，因为Google切换到支持Android Studio的AAR文件

我发现所有的Google Play服务AAR模块都扩展到了单独的Android项目中。我已经下载并导入了用于分析和Admob的适当项目，如下所示（）

我的项目成功编译，没有错误，因此所有类都可以访问并正确链接

然而，当我在运行安卓6.0.1的Nexus 5上启动时，我会不断收到以下信息：

从我的研究中，我所看到的只是一个（旧的）影响姜饼设备的缺陷，但我认为这不适用于这里

按要求编辑：我的build.gradle文件。不确定是否相关，因为我没有使用此链接将依赖项链接到Google Play服务，但它仍然存在：

所以第二天，我添加了Android库“play services Basic”作为我项目的依赖项，一切正常。没有意识到我需要将其作为依赖项直接添加到我自己的项目中，因为admob/analytics projects也隐式添加了它。

您可以发布您的Gradle文件吗？@nitinsh99当然可以，用它编辑了我的问题。您可以尝试在依赖项中添加：compile“com.google.firebase:firebase ads:9.0.0”吗？确保清理您的项目并重新同步gradle。@nitinsh99我以前玩过这个。我按照你的建议做了，Gradle没有下载任何新的东西。所以我把

com.android.tools.build:gradle

从1.3.1改为2.0.0。现在，在尝试刷新Gradle依赖项时，它只给了我一个错误：按照错误所说的那样，继续更改包装器版本，必须清理一些其他内容以使其刷新依赖项。仍然没有下载任何新内容，所以project只是显示“无法解析为类型”错误。
