It is very convenient to develop android in eclipse. you can install and configure JDK/Eclipse/ADT/Android SDK one by one.
The android SDK does not have source code. Many times, the is prompt will be stuck (find the prompt result from the Internet? I don't know why, in short, it's very stuck ..)
In addition, if there is no source code, there is nothing like a hyperlink or the past. I'm not used to it either. Fortunately, Android is open-source, or the source code!
During Android development, git (distributed, it is said that Linus spent a week writing it .. Ele. Me, time is not a problem. The problem is that it is easy to use and soon it will be in Linux !) Maintained.
Therefore, you can use git to obtain and submit the source code. Address: http://android.git.kernel.org/
I installed the 1.5/1.6/2.1/2.2/2.3 SDK. The source code package is not found on the official website, but someone has packed it online and downloaded it by address:
1.5 address: http://rgruet.free.fr/public/android-1.5-cupcake-src.zip
1.6 address: Workshop. Decompress the package and place it in the SDK/platform version. Then we can track the code in eclipse. Reference: callback.
