Android Development prompts in eclipse that this element neither has attached source nor attached javadoc

Developing android with eclipseProgramDuring the process, you find that the mouse is parked on the class name you want to view help with, and the following message is displayed:

Note: This element neither has attached source nor attached Javadoc and hence no javadoc cocould be found.

This is generally because the association attribute of the javadoc file of the android. jar package is not set.

You can perform the following operations:

1. Right-click the project and choose Properties> JAVA build path> libraries to expand the attributes of the Android-related class libraries. The following is an android. jar, expand its properties, and find a javadoc location (none). Click this item, select the edit button on the right, and add the javadoc path: http://developer.android.com/reference , click OK.

2. If the path in the javadoc location already exists, check whether the path is correct.
