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

where and what do i need to attach?

If you have installed the ADT plugin to Eclipse then you should make sure that you download the package called something along the lines of "Documentation for Android SDK 2.2, API 8, revision 1" or whatever. Have you gone through the entire installation guide for the Android SDK as posted on the official website? http://developer.android.com/sdk/installing.html this is the one I'm talking about. It's been discussed on SO before as well: JavaDoc in an Eclipse Android Project

If you have done all this, then http://www.vogella.de/articles/Eclipse/article.html#classpath_jarjavadoc does a good job of explaining how to add Sources & Javadocs to existing Libraries in case something went wrong.

For example, this is how my Libraries path looks:

Go check and see how yours looks. Included is the location for the Javadocs normally (SDK Path/docs/reference/)

If you want to add the source code as well, see: http://android.opensourceror.org/2010/01/18/android-source/ & http://stuffthathappens.com/blog/2008/11/01/browsing-android-source-in-eclipse/
