我们的Andr​​oid应用程序需要的JAR   文件住的lib文件夹中   我们的项目

把它放在库/ 文件夹，一切都将自动运行。我不知道你的应用程序什么可能要求的lib / 目录中，而不是库/ 。

Im using an ant build file that has been generated by android. Our Android application requires a JAR file that lives inside the lib folder of our project, so I need to adjust the classpath that ant is using when it builds stuff.

When I run:

ant -lib lib debug

the project builds just fine, but this should really be inside the build file itself. The build file that android generates references the android_rules.xml so a lot of this stuff is automated. I guess my question, what the best practice here when working with the Android build rules ?

Put it in the libs/ folder, and everything will work automatically. I do not know what in your application could possibly require the lib/ directory instead of libs/.
