我正在使用Java 1.7在Win 7 x64上使用3天的adt 17下载。
将jar添加到我的新示例项目中（通过将其复制到libs /）可以正常编译，但是会在运行时抛出该错误，因为jar中的类不在dexedlibs /中的相应jar中-该jar仅包含一个清单。
相关链接：http://android.foxykeep.com/dev/how-to-fix-the-classdefnotfounderror-with-adt-17和http://tools.android.com/recent/dealingwithdependenciesinandroidprojects。
进行链接中建议的某些导出和订购操作无济于事。
这些天怎么知道如何将jar添加到android项目中？
编辑：感谢max：罐子是使用Java 1.7制成的，指定1.6停止了抛出，但是由于某种原因我仍然得到一些缺少的方法（这些没有被调用，但是被引用了）。

更新：导入具有简单类的jar效果很好。
最佳答案
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：
右键单击该项目->属性-> Java构建路径->库
选择“ JRE系统库[JavaSE-1.7]”，然后单击“编辑”。
将执行环境更改为JavaSE-1.6（jre7）
这使用ADT 21对我有用。
