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 buffer at runtime? If not, then assuming I can rebuild the Android image, how do I change it at compile time? I’m looking to enlarge it for diagnostic purposes.

According to the newsgroup Android Developers, logcat buffer size:

The log buffers on the device are 64 KB. The timestamp, process ID,
and log level are stored in a compact format, so you may actually get
more than 64 KB of formatted data out of logcat -d -v <mode>.
