android documentation
in this web page, it overview the android platform, and support all information if you want.(but i think it’s not enough ^^”) install SDK is easy, just set up the path of OS.i think install SDK isn’t problem, so let me see the API.

the API rough separate in three parts:

1. java.*; and javax.*;
2. android.*;
3. com.apache.http.*;

the first part(java.*; and javax.*;) import from java SDK. so it’s not new package, however, pay attention to these are not awt and swing package, because android platform exericse other UI Design, so we should use android package to do UI Design. after that, the third part import from com.apache for parsing html document.
