Android 抓取 ANR 日志終極辦法

原文連接：技術(shù)小黑屋-Android 抓取 ANR 日志終極辦法
在 Android 開(kāi)發(fā)中瞄桨，有時(shí)會(huì)遇到 ANR坯临，一旦出現(xiàn) ANR 我們就需要拿到對(duì)應(yīng)的trace 文件來(lái)分析并解決。本文將介紹兩種獲取 ANR 的方法捍壤。

第一種

直接查看/data/anr/traces.txt的內(nèi)容,如下

adb shell cat  /data/anr/traces.txt

或者類似使用拷貝到電腦上查看，比如

adb shell cp /data/anr/traces.txt /sdcard
adb pull /sdcard/traces.txt ./

但是這種方法在某些手機(jī)上由于權(quán)限原因童太，無(wú)法進(jìn)行烫罩，就需要了使用下面的方法了洪己。

第二種

這種方法就是進(jìn)行adb bugreport，沒(méi)有權(quán)限限制問(wèn)題蠢棱。具體步驟是

生成 bugreport 文件

使用命令

adb bugreport

生成文件

/data/user_de/0/com.android.shell/files/bugreports/bugreport-sailfish-QP1A.191005.007.A3-2021-01-12-15-30-21.zip: 1 file pulled, 0 skipped. 30.6 MB/s (3897489 bytes in 0.121s)
Bug report copied to /private/tmp/bugreport-sailfish-QP1A.191005.007.A3-2021-01-12-15-30-21.zip

進(jìn)行解壓文件

unzip bugreport-sailfish-QP1A.191005.007.A3-2021-01-12-15-32-54.zip

解壓文件
