Java Source Code Attachment in Eclipse

How to change Eclipse's “associated source” for debugging?

In the package explorer, where the jar is in a library (JRE, Maven dependencies, etc...);
right click => properties => java source attachment.

Alternately in the project properties => Java build path => Library tab => select the jar => edit.

as for eclipse 4.3.1, only method 1 works.

打開某class   (e.g. import android.app.ActionBar; )
會跳出 source file not found錯誤訊息的那頁 有個可以讓你設定的按鈕
"change attached source"

External Folder
choose
<sdk>\sources\android-19

=========

不必再用External File (add external jar)

即以下都不必做  (不必再另外下載jar檔)

I usually refer this site for the android source code.
