I'm having a build problem with a specific file that I'm not being able to change the path on my Android project. Here is a picture of the problem:

How do I change this Path: /Users/apple/Downloads/dolphin_player/p/libs shown in the picture?
It depends on the which version of java you are using.Just go to library tab and do following.
If you are using the 1.6 version of java the whenever you want to add any third party jar files you have to add it by adding external jar file in the library option.
If you are using the 1.7 version of java then you have to make a folder called libs and put the all the external jar files in this folder. It will automatically add the files to yous build path and add it in "Android Dependencies".
