Solution: Unable to associate source code with Android in eclipse

android. jar cannot be bound to Source Code . It is very painful to debug it. I searched the internet for it, I found that someone has done this. I want to share with you two methods:
1. is to create a sources directory in your android JDK directory, the download the android source code to copy it. Specifically, you can copy mydroid_src/mydroid/frameworks/base/CORE/ copy content in Java /to the sources directory
SDK _ path
| android. jar
+ -- docs /...
+ -- samples /...
+ -- sources
+ -- Android
|... accounts, annotation, app, Bluetooth, Etc...
+ -- COM/Android/etc...
+ -- Dalvik /...
+ -- Java /...
+ -- javax /...
then you can proceed.
2. it's easy to introduce android to the user library. jar has no constraints.
