How to change size of logcat buffer in Android?

Question

I noticed that the size of the logcat buffer varies on different devices. Assuming I have root permissions on my device, is there a way to change the buffer size of the main

Answer 1

To set logcat buffer to 16Mb for a specific Android device through adb, I used:

adb -s 2615a1d4e3174a6e logcat -G 16M

But you can use just:

adb logcat -G 16M

Or set previous buffer size with:

adb logcat -G 256K

Answer 2

Set the size of the log ring buffer

adb logcat -G <size> 

Append K or M to indicate kilobytes or megabytes

Example: adb logcat -G 512K
