1.Android設(shè)備本地異常日志

adb shell
/data/tombstones
/data/anr
/data/system/dropbox

ANR發(fā)生進(jìn)程主線程堆棧信息

--------- beginning of system
--------- beginning of events

"main" prio=

(1).查看UI線程，搜索main

main

----- pid
Cmd line：
Cmd line: system_server

Cmd line：后邊跟的是APP應(yīng)用的包名，包名能對(duì)上就能定位成功異常日志

(3).Native發(fā)生異常

"main" prio=5 tid=1 Native

beginning of crash
--------- beginning of crash

(1).aarch64-linux-android-addr2line工具所在路徑

H:Androidandroid-sdk-windowsndk21.1.6352462toolchainsaarch64-linux-android-4.9prebuiltwindows-x86_64bin
H:Androidandroid-sdk-windowsndk21.1.6352462toolchainsarm-linux-androideabi-4.9prebuiltwindows-x86_64bin

(2).解析錯(cuò)誤符號(hào)地址的命令

aarch64-linux-android-addr2line -C -f -e <對(duì)應(yīng)帶符號(hào)表的so庫(kù)> <8位內(nèi)存地址>

./aarch64-linux-android-addr2line -C -f -e /android_arm64/libNvStreamingSdkCoreSymbol.so 0005f29dc

注意:這里的so庫(kù)是對(duì)應(yīng)的帶符號(hào)的so庫(kù)才可以

8.抓取Android日志的常規(guī)方法

adb logcat -b all > logcat_all.txt           (抓全部日志)
adb logcat -s *:E > logcat_err.log           (抓錯(cuò)誤日志)
adblogcat-s*:I(抓INFO或以上級(jí)別的日志)
adblogcat|grep$(adbshellpidofxxx.xxx) (抓某一進(jìn)程的log)

9.快速搜索定位空指針異常日志

null pointer dereference
