android 系统裁剪

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，我们尝试将其裁剪出去。
####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：

对于一些服务 可以修改 frameworks/base/services/java/com/android/server/SystemServer.java

将里面的相关的 systemserver.java 去掉。

例如：

            mContentResolver = context.getContentResolver();

//            Slog.i(TAG, "Camera Service");
            // mSystemServiceManager.startService(CameraService.class);

          
            traceBeginAndSlog("StartAccountManagerService");
