android dsi 源码分析,Android 调试系列-Bugreport实战篇
Bugreport
上一篇文章Bugreport源码篇主要是从源码角度来分析了一下系统是如何生成Bugreport的，以及Bugreport的源码实现。本篇主要从使用角度来对Bugreport中包含的内容做相关介绍。也是基于Android 8.0版本，由于Bugreport获取的内容很长，这里只能简单划分如下21块内容，简单说说各部分log的信息。
注：这里拿小米手机dump的bugreport内容来做介绍
1、系统build相关信息

系统build信息如下:
dumpstate:date
Build: getprop ro.build.display.id
Build fingerprint: getprop ro.build.fingerprint
Bootloader: getprop ro.bootloader
Radio:getprop gsm.version.baseband

Command line: cat /proc/cmdline
系统运行时间：
------ UPTIME (uptime) ------
00:22:55 up 4:42, 0 users, load average: 44.10, 46.18, 42.83
------ 0.018s was the duration of 'UPTIME' ------
up即为uptime:系统运行时长00:22:55
idle time:系统空闲时长4:42
user:用户数0
load average:cup 最近1min,5min,15min的平均负载情况.这个值的标准由cpu有多少个核来决定
2、下面列举bugreport结果相关项
