When building the Android SDK using the Eclipse. You will find that using "tooltip description " is not showing the Java document in Eclipse by hovering the mouse over the method. Note that you will find descriptions " The Javadoc for this element could neither be found in the attached source nor the attached Javadoc."
Solving the problem: go back to the "Available packages" tabs of the AVD manager(which is the SDK device manager in Eclipse) and install the doc package.
done!
