看了一下google发布的Android SDK。这个SDK带的模拟器是基于qemu做的，模拟的CPU是ARM926EJ-S。内核是Linux，版本居然是簇新的2.6.23。而且我发现还开启了SELinux，看来想溢出Android是没戏了。网上无数人贴Android的运行界面，我这里贴点内核启动信息让大家看看爽一下：

以前零星听到关于google要涉足手机市场的消息时，我还有些纳闷：智能手机市场的争夺其实主要是软件的争夺，google如何跟发展了这么多年的WM和Symbian争天下？Moto当年的试水linux的时候，基本就是死在这个原因上。最近我逐渐明白了：有钱，一切皆有可能。

首先，google花钱砸出了一个兼容java的“gava”。也就是说，你用java写的程序，拿gava的编译器可以直接编译，然后就可以在Android上运行。这样既绕过了sun关于java的许可证限制，又解决了以前那么多基于j2ee/j2me开发的手机程序的兼容问题。

第二，google拿了一千万美金作为奖金，搞了一个基于Android的编程竞赛。50个入围的，每人可以拿2.5万；10个银奖，每人10万；10个金奖，每人27.5万（算一下，这好像才500万，还有500万干吗用了呢？）。可以想象一下，那些辛辛苦苦写ListPro、Handstory的程序员们得卖多少份软件才能卖出27.5万啊。此举一定会吸引大批给Windows CE、PALM、Symbian写软件的人们来尝试一下。

解决了软件来源问题，其它就都好办了。作为手机厂商来说，有这么一个不花钱的平台可用，何乐而不为呢？所以包括微软的老搭档HTC在内的几乎所有大手机厂商都和google达成了合作协议。

顺便说一句，我发现Android居然内置了中文字体，我估计应该CJK都可以：



很多年前，业内就有人说linux未来最大的发展将是嵌入式领域，其次才是服务器。Android的出现，也许会成为Linux嵌入式时代的一个里程碑。
