Android bugreport 概述
bugreport 是Android 系统下的一个工具,功能类似于系统的一个黑匣子;通过执行相应的命令可以获取到bugreport 包,其中包含设备日志,堆栈跟踪和其他诊断信息,可帮助您查找和修复系统错误;bugreport信息量非常之大,几乎涵盖整个系统各个层面内容,对于分析BUG是一大利器
生成 bugreport
直接 adb bugreport 生成
adb bugreport

Android bugreport 内容分析
直接生成的是一个zip 包,大概有20M大小;
bugreport-xxxxx-2022-07-26-09-29-01.zip
解压后目录如下所示:
- FS 是一个目录包含下面子目录:
data data下的关键信息如 tombstone,ANR,logd信息等
proc 各个进程procfs 的dump信息
linkerconfig TBD - lshal-debug 关键HAL进程的 lshal信息
- proto TBD
- bugreport-frost-RD2A.211001.002-2022-07-26-09-29-01.txt
系统信息的关键文件,解析见下文 - dumpstate_board.txt 执行bugreport 的dumpstate 进程信息
- main_entry.txt dump出的文件名
- dumpstate_log.txt 执行dumpstate 的log 信息
- version.txt TBD
- visible_windows.zip TBD
如果发生了ANR,crash 等事件,FS下的内容是至关重要的,ANR的trace 和 tombstone 文件都可以找到,具体可以结合bugreport txt 文件分析
bugreport-xxx-211001.002-2022-07-26-09-29-01.txt
这个文件包含了system dump 的ALL info 和 dump 时间点前后的log,包含的内容为:
系统信息:
dump时间点,系统版本,内核版本,运行时间,Bootcmd

chkbugreport 工具
因为bugreport 中包含了太多的信息,查找分类信息很困难,所以有分析bugreport txt文件的开源工具 chkbugreport;作用是分析析处理手机上生成的bugreport,并且为开发者提取尽可能多的有用数据;
chkbugreport 工具下载与使用
参考地址:
https://github.com/sonyxperiadev/ChkBugReport/wiki/How-to-install-it
1:先下载下来
git clone https://github.com/sonyxperiadev/ChkBugReport.git
然后在把这两个下载下来
http://sonyxperiadev.github.io/ChkBugReport/download/chkbugreport (Launcher shell script)
http://sonyxperiadev.github.io/ChkBugReport/download/chkbugreport-0.5-215.jar (The application itself)
放入到 :
刚刚下载下来的 路径
ChkBugReport/core
解析 bugreport.txt 文件
java -jar chkbugreport-xxx.jar "bugreport-riva-OPM1.171019.026-2020-10-30-16-06-24.txt"
命令执行完成后,会在命令执行目录下生成一个与日志文件同名的目录
进入该目录,双击index.html文件,可查看日志信息
这个就是刚进来的目录
