我正在使用java 1.7在win 7 x64上使用3天的adt 17下载。
在我的新示例项目中添加一个jar（通过将其复制到libs /）编译得很好，但是在运行时抛出，因为jar中的类不在dexedlibs /中的相应jar中 - 该jar只包含一个清单。 / p>
相关链接：http://android.foxykeep.com/dev/how-to-fix-the-classdefnotfounderror-with-adt-17和http://tools.android.com/recent/dealingwithdependenciesinandroidprojects。
执行链接中建议的某些导出和订单操作无济于事。
这些天如何知道如何将jar添加到android项目中？
编辑：感谢max：jar是用java 1.7制作的，指定1.6停止了抛出，但由于某种原因我仍然得到一些缺失的方法（这些没有被调用，但它们被引用）。

更新：使用普通类导入jar工作正常。

如果您使用的是Java 7，则可以尝试更改Java库项目的运行时环境：
右键单击项目 - ＆gt;属性 - ＆gt; Java构建路径 - ＆gt;库
选择JRE系统库[JavaSE-1.7]并单击编辑
将执行环境更改为JavaSE-1.6（jre7）
这对我使用ADT 21很有用。
