about how to view Android-support-v4.jar source code

Just learning the use of Viewpager, so want to watch its source code. The internet to find a lot of information about the steps below

1: Find Libs/android-support-v4.jar, build path-add to build Path

2:java Build path-libraries

Android-support-v4.jar

Click Source Attachment and edit

Select External location-external folder to find the path XXXXX\SDK\EXTRAS\ANDROID\SUPPORT\V4\SRC

Most of the Internet only said this step, but the individual is always unable to view the source code, until later found a method

3:libraries Select Android Private libraries to remove it

At this point you can watch the source code, personal guess there are a lot of people's way there is no third step may be because the previous use of Android-support-v4.jar all need their own association, and now eclipse automatically set it as the Android Private Libraries, The Android-support-v4.jar priority in Android Private libraries may be higher than referenced libraries, so the source cannot be viewed.

Haha, just run unexpectedly error, connect not on Android-support-v4.jar, after troubleshooting plus fourth step ~ ~

4:java Build Path-order and Export Android-support-v4.jar selected
