Android 使用AdView时的“ClassNotFoundException:org.json.jsoneException”

我没有在我的应用程序上使用json，但我收到json错误，为什么？请帮帮我。当我删除com.google.ads.AdView时，它正在工作，但那时我的广告将无法工作。我使用的是android 4.2，我将admob.jar添加到库中。我已经关注了admob的所有android开发者页面和getstarted页面。但找不到理由

您没有说stacktrace是Eclipse IDE提供的开发时stacktrace。这不是一个运行时错误

---

本质上，这意味着您尚未配置Eclipse环境，因此Android SDK将在类路径中运行。

java.lang.ClassNotFoundException:org.json.jsoneException是原因，但是hmm。。它从API 1开始就存在了。我不知道你为什么要使用admob.jar。它将被弃用。那么我应该使用什么？我是一名优秀的开发者，我只是通过观看视频来开发我的应用程序？
