Where can I get source code for apps on the Android emulator?

I have two question to put forward:

1. I was very interested, even intrigued by the Maps application on the android emulator. Where can I get the source cod开发者_如何学Ce for it?

2. There is a Maps Editor on the Android Market, it cannot be downloaded to the emulator. But again, where can I find the source code to that?

You can't -- that is a proprietary application. Source code is not available.

If you are referring to "My Maps Editor by Google", that too is a proprietary application as far as I know. It is actually a part of the Google Maps application for Android 1.6+, according to one of the comments. I do not believe there is source code available for it.
