1.屏幕尺寸Screen size 即显示屏幕的实际大小,按照屏幕的对角线进行测量。 为简单起见,Android把所有的屏幕大小分为四种尺寸:小,普通,大,超大(分别对应:small, normal, large, and extra large). 应用程序可以为这四种尺寸分别提供不同的自定义屏幕布局-平台将根据屏幕实际尺寸选择对应布局进行渲染,这种选择对于程序...

首先,要编译出一个可以使用的手机rom,一定需要的是手机的device,device存放的是手机的一些配置文件,hal层源码,及一些驱动源码等等,当然,还有一些预编译的文件(就是预先编译好的),vendor则是存放一些手机厂商的系统文件,由于厂商不开源及其他原因,使用预先编译好的文件。还有内核源码,这个可要可不要,如果有预编译内核...
