开机按键日志分析

1、Android启动第一阶段：启动第一个Android进程init，通过解析init.rc脚本生成文件系统，启动vold、media、SurfaceFlinger等Nativie服务。在此阶段您可以看到带有文字“Android”的静态徽标和带有文字“android”的开机动画

[3.947876] 找不到init: /dev/hw_random

========正常打印，找不到/dev/hw目录

[3.952580]init:无法打开“/initlogo.rle”

==========正常打印，第二个启动画面的内容由文件/initlogo.rle指定。

如果文件/initlogo.rle不存在，或者显示它时出现异常，则函数load_565rle_image的返回值将等于-1。此时，函数console_init_action将以文本的形式显示第二个启动画面，即向编号为0（/dev/tty0）的控制台输出一个带有“ANDROID”文本的静态标识。

[4.019576] init:

[4.019583]无法挂载pstore pstore /sys/fs/pstore ret=-1 errnostr=没有这样的文件或目录

[4.049219] EXT4-fs (actc): 使用有序数据模式安装的文件系统。 opts: noauto_da_alloc

[4.070701] EXT4-fs (acte): 使用有序数据模式安装的文件系统。 Opts: 节点分配

================正常打印，挂载文件系统，部分挂载错误，主要是文件不存在

[6.397025]init:值=512misc信息读取类型=0，大小=32

[6.417399]init:无法打开/data/system/entropy.dat

========打印正常，打开/data/system/entropy.dat时出错，

[6.435154]healthd:wakealarm_init:timerfd_create失败

========正常打印，创建timerfd_create时healthd进程失败

[6.453868]binder: 1140:1140事务失败29189，大小0-0

[ 6.497618] init: 属性“sys.powerctl”在扩展“${sys.powerctl}”时不存在

[6.506132] init: powerctl: 无法扩展“${sys.powerctl}”

========解析属性值时发生错误。打印正常。

12-31 16:00:06.510 I/installd(1342): 安装启动

========启动守护进程installd服务：apk安装服务

01-07 06:21:37.160 I/Vold (1326): Vold 2.1（复仇）火力全开

01-07 06:21:37.170 D/Vold (1326): 卷sdcard 状态更改-1（正在初始化）-0（无媒体）

========启动卷服务：主要用于管理USB/SD卡等外部存储设备。该平台可以操作和轮询外部存储设备的状态。当外部存储设备的状态发生变化时，卷服务也会实时向平台报告。

01-07 06:21:37.500 I/SurfaceFlinger(1333): SurfaceFlinger 正在启动

01-07 06:21:37.500 I/SurfaceFlinger( 1333): SurfaceFlinger 的主线程准备运行。正在初始化图形硬件.

=======启动SurfaceFlinger服务：合成图像并显示到屏幕上。启动服务的时候，会触发init启动一个bootanimation进程，这个进程就会开始动画显示，也就是我们看到的带有“android”字样的启动动画。
