android 系统裁剪 ​

有时候编译android镜像会用到一些不需要的app和系统服务，咱们测验将其裁剪出去。
####1、源码目录
build/target/product/*
在此下面有不少*.mk文件，这一找到相应的app进行规避修改：

关于一些服务能够修改frameworks/base/services/java/com/android/server/SystemServer.java
将里边的相关的systemserver.java去掉。
例如：
mContentResolver=context.getContentResolver();
//Slog.i(TAG,”CameraService”);
//mSystemServiceManager.startService(CameraService.class);
