Android Development tips for viewing external dependent jar source _android private libralies does not allow modifications to source

When you develop an Android application in Eclipse, sometimes you want to see the internal implementation of the function, but when you click CTRL and the left mouse button on the function,

The following tips often appear:

Class File Editor

Source not found

The JAR of this class file belongs to Container ' Android ' which does not allow modifications to source attachments on its Entries.

The most common is that android-support-v4 can not see the comments and source code, the mouse on the class prompt:
