2. Associate Android source code

Note that the android source code is not only associated with the kernel source code, but only the source code in the Android. jar package.

Kernel source: http://source.android.com/source/downloading.html

My development environment is 4.0, So download Android 4.0 source code http://download.csdn.net/detail/tianmi1988/5021734

Decompress the source code and put it in the sources directory where Android. jar is located. For example, I developed the SDK Based on android4.0.3,

The Directory of Android. jar is D:/program files/Android-SDK-Windows/platforms/Android-15,

Create a New Sources folder in this directory and put the source code in it. After eclipse is opened, ADT will be automatically associated with the source code.

Or manually add the ZIP or jar package. Right-click Android. jar to add the zip download path.

In addition, when we can use Android SDK manager to download the source code, it will automatically download the associated source code.

Usage: 

You can select the type, method, or field name in the Java source code editor or code fragment editing test window, and then open the editor for element definition.

In the Java Editor, select the type, method, or field name. You can also click it only once in the name.
Perform one of the following operations:
1. Select Browse> open declaration from the menu bar
2. From the editor pop-up menu, select open declaration
3. Press F3
