如何在Android Studio中从连接的设备读取存储的日志

Question

I need to read the logs that are stored in a device that I have attached by USB. It's set up for debugging. I run the Device File Explorer and it shows all the files. But where are the log files hidden?

Answer 1

AFAIK, the Android System does not keep a Log File, rather it has a temp buffer which contains logs.

Approach 1:Write logs to file in internal storage through code

You need to write logs to the device by yourself. There are libraries like logback-android which can assist in doing so. You just need to create proper configuration in order to write logs on the device storage.

Approach 2: Write logs to file using adb command

Since you are connected through USB you can do

adb logcat -d > logcat.txt

The above command stores file on PC and not on device. Its in the same directory pointed by the command prompt

Approach 3: Use Android Studio

Connect your device to PC and run Android studio. At the bottom, you have logcat tab. You can view the logs and also save them to a text file.
