我的pom.xml 中有以下构建配置，它位于我的项目根目录中：

我认为错误来自 API 版本，但自 Jelly Bean 以来支持 @JavascriptInterface，所以我不知道是什么情况......

【问题讨论】：

您找到解决方案了吗？我有完全相同的问题，但什么也没找到...

标签： java android maven

【解决方案1】：

您需要找到另一个注解依赖项，因为 com.google.android:android:4.1.1.4 不包含任何名为 JavascriptInterface 的类（com.google.android:annotations:4.1.1.4 也不包含)。

这个maven repository search 会给你所有包含JavascriptInterface 的罐子。
