Android javadoc does does not display

I am having a problem with my android standard library javadoc, it does not show up when I hov开发者_运维技巧er over Objects in my code.

Example: android.app.Activity

Note: This element has no attached source and the Javadoc could not be found in the attached Javadoc.

I have tried changing the Java Build Path to point to

C:/Program Files/Android/android-sdk/docs/reference

However, I hit validate and then ok and the location changes back to :

file:/C:/Program Files (x86)/Android/android-sdk/docs/reference

Before- Images shows me changing the path

After- images shows eclipse reverting javadoc to the location back to the original location

I am trying to pick-up some android for a school project, and having that Javadoc would be awesome!

BTW: 1. i have tried following these steps: http://hacksoflife.blogspot.com/2011/02/losing-javadocs-in-eclipse-solution.html

2. I have the java doc installed in can open the file in my browser in the C:/Program Files/Android/android-sdk/docs/reference location

Thanks in advance to whoever solves this !

you must download the Documents for the current Android API Version, you can download it from eclipse menu: Window >> Android SDK and AVD Manager >> Available packages ! then select the API Version match your need.
