我有一个，我想在我的Andr​​oid应用程序使用的JAR形式的API。不知道是否应该在Eclipse项目的一部分，或保持独立，并添加到项目属性。这个JAR还需要与应用程序打包，所以这是怎么一回事for Android应用程序？

I have an API in the form of a JAR that I would like to use in my Android app. Not sure if it should be part of the project in Eclipse or kept separate and added to the project properties. This JAR also needs to be packaged with the application, so how is that done for Android apps?

推荐答案

作为解释本SO问题：

您的项目 - >右键 - >导入 - >存档文件 - > yourjar.jar 您的项目 - >右键 - >属性 - > Java构建路径 - >库 - >添加罐 - > yourjar.jar Your Project -> right click -> Import -> Archive File -> yourjar.jar Your Project -> right click -> Properties -> Java Build Path -> Libraries -> Add Jar -> yourjar.jar

您必须将其添加为外部JAR的文件，并设置您的Eclipse项目的排序和导出。

You must add it as "external JAR" files, and set the "Order and Export" in your Eclipse project.
