如何获取android.jar的源代码

Question

I'm not actually working on android devices, but I'd like to use the android java std lib for a project of mine. I'm extracting the android java std lib from the android ADT here:

http://developer.android.com/sdk/index.html

After unzipping the bundle, it's in

adt-bundle-windows-x86_64-20130729\sdk\platforms\android-18\android.jar

However, when I open this up in Intellij, it doesn't show any source code: all methods are just labelled as "compiled code"

Is there any way to get the source code (in a jar or otherwise) for the android.jar so I can hook it up to the IDE so I can nicely browse the source code of the standard library? I've dug through the sdk download bundle and haven't found anything.

I have no idea why you think that would work, any more than trying to use a Windows DLL on Linux.

The source code for Android is at the Android Open Source Project . The source code for the android.jar is mostly in the platform_frameworks_base repo ( GitHub mirror ), but the JAR is really an output of a firmware build.

In your Android SDK root directory, go to the sources folder. Here you will find the source files for the different platforms you have downloaded.

Note: This gives you the Java code for Android libraries such as Activity

Unpacking the jar is way more than you need to worry about. Android is open source , so you can get everything you need online. To start, you can browse most of the source on Android's GitHub account , or download the source tree on the Android Open Source Project website . You can also view most (if not all) sources on GrepCode .

If you really want to go through the trouble of extracting the jar and decompiling the source, you can use JD-GUI .
