1.Android系统源代码目录与系统目录

1.Android源代码的目录中包含了Android系统所有的源代码，从底层驱动到上层应用，Android系统对所有文件都进行了详细管理；
2.而在手机中，Android系统的目录与源代码的目录并不是一一对应的，而是源代码编译之后，与打包生成的Image文件的结构相同；
3.了解这些目录的结构，对于认识整个Android系统有很好的帮助。
1.Android系统源代码目录
想要看完整个Android的源代码，需要懂C、懂脚本、懂Java、软硬兼通。所以一般情况下，我们了解源代码的框架结构，出了问题知道从哪里着手解决就可以了。这就好比图书管理员，他不一定要把所有的书都读一遍，但是只要有用到，他就可以很快地找到相应的资料。
这里是查看Android源代码的网站。其界如下：
每个目录都具有不同的功能和目的，整个结构关系图如下所示：
2.Android系统目录
在Android手机里，系统的目录结构与源代码目录结构还是有所不同的，我们通过ADB连接上手机，通过Linux的ls命令查看Android系统的根目录。其中/system和/data是开发者非常关心的两个目录。
