android project starts

我买不起G1

买不起Iphone

也买不起mac book

iphone这玩意儿虽然好，但是想开发他的软件成本太高，因为他的SDK只能跑在MAC OS上，vmware也没找到MAC OS 的镜像，而且，虚拟的系统未必就没问题，所以就不考虑了~~

作为google的粉丝，没有不支持Android的道理。

现在就停掉ruby on rails的进度，开始Android。

哈哈，Android is alive ~~~~~~~~~~~~~~~~~~~~~~~~~

 

笔记。。。。。还没开始碰下面这些玩意儿，先记一下。

there are 4 building blocks to an Android application:

1:Activiry
2:Broadcast Intent Receiver
3:Service
4:Content Provider
not every application needs to have all 4 building blocks, but your application will be written with some combination of them.

AndrioidManifest.xml: describ all components and their information.
