Android source code issue. . .

            
Encountered a problem while viewing an Android source files, can not think of one herself, ask Daniel to help. .

Problem Description: Android source code Resources.java NativePluralRules.java this class has a class, I want to see the source code described in this class, but hold down the Ctrl key in Eclipse environment but can not open the file, it does not show the link of this class When I use this class in your own code is, but it is showing no class, to create your own. By looking at the package name, that NativePluralRules this class is in libcore.icu.NativePluralRules this library. Android does not belong to you? How to get this thing the source of it? Android is not open source it? Is that what happens?

Brother knowledge has limitations, please enlighten ~ Thank

Resources.java relevant code

 import libcore.icu.NativePluralRules;

private static final LongSparseArray  sPreloadedColorDrawables

Correlation method code

throw new NotFoundException ("Plural resource ID # 0x" + Integer.toHexString (id)

} 

private NativePluralRules getPluralRule () {

Amount, Dinga. . Seeking to explain. . .
Is it because it comes to the bottom of the library? ?

Search to find the next one .. I do not know right.

Ah is this library. . . But in Eclipse, no. . . Download Android Android.source when the association of this package. . Estimate is that it does not contain this package. . . .

Thank you!

Also ask you this study is to download the source code down?

You do not just want to look at the source?
android source code is not compiled with eclipse it.
Search should be able to download the source code can be compiled to search.
