第一步拿到anr日志文件(低版本手機獲取ANR日志方法)

bogon:wyze-doorbell-wireless-android-14 xiayiye5$ adb shell 進入手機目錄 HS8917QC:/ $ cd data/anr 進入anr目錄 HS8917QC:/data/anr $ ls 查看anr日志列表文件 traces.txt traces.txt.bugreport HS8917QC:/data/anr $ ls -l 查看anr最近的一次列表文件 total 6408 -rw-rw-rw- 1 system system 591360 2021-05-11 10:36 traces.txt -rw-rw-rw- 1 root root 2679219 2021-05-11 10:24 traces.txt.bugreport HS8917QC:/data/anr $ exit bogon:wyze-doorbell-wireless-android-14 xiayiye5$ adb pull data/anr/traces.txt 將anr文件復制到當前項目目錄 data/anr/traces.txt: 1 file pulled, 0 skipped. 22.3 MB/s (591360 bytes in 0.025s) bogon:wyze-doorbell-wireless-android-14 xiayiye5$

Google官方grep執(zhí)行am_anr和ANR in命令方法：點擊查看官方(實際上這兩個命令就是類似與搜索這個文件中的關(guān)鍵字"am_anr"和"ANR in")

如果上面方法獲取不到，可以使用高版本手機獲取方式

adb bugreport(高版本手機獲取ANR日志方法，高版本中的anr日志和低版本anr目錄日志默認是一樣的都在data/anr下面)

獲取后解壓可得到anr日志在根目錄/FS/data/anr下面就是ANR對應的日志文件

Android Studio打開profile的方法
