I want to get ANR traces from my Samsung A51.
Official documentation tells to do adb root:
adb root
adb shell ls /data/anr
adb pull /data/anr/<filename>
But it does not work for my device. Why? Or everyone assumes that developers have rooted devices?
So, it seems to vary device-to-device. Probably safe (enough) to say OEM-to-OEM.
On our LG test devices, you can just call
adb pull data/anr .
and go to town.
On our Google Pixels, you'd be met with "remote open failed: Permission denied", and adb root doesn't work without modifying or replacing the default adbd installation.
You can get around this by using:
adb bugreport
unzip bugreport-*.zip
rm bugreport-*.zip
cd bugreport-*
ls -lt FS/data/anr # here they be
# also good stuff:
ls -lt FS/data/tombstones
