Logcat crashes with error: unexpected EOF

Fuller answer

The accepted answer didn't work for me. Rather than turning the logger buffer off, I increased it to the max size.

1. Enable developer options in your emulator or device (not Android Studio) if it hasn't been enabled already: In your emulator or device go to Settings > System > About (emulated device) and click on Build number 7 times.
2. Go to Settings > System > Developer options > Logger buffer sizes and choose a higher value.

3. I also had to restart the emulator.

So the original problem apparently happens because the devices log buffer gets filled up for lengthy logging. Increasing the buffer size allows you to log more in a single logging session.

Try setting Logger buffer sizes to off under Settings->Developer options, on your device/emulator. This might be happening because Logger buffer is configured to display limited KB of logs only at a particular time. Next set of logs would only be displayed once previous buffer is cleared.

In Developer options you can set Logger buffer size to maximum 16M.
(Setting > System > Developer options > Logger buffer sizes)

If you need more you can set it using adb.For example you can set it to 100M:

adb logcat -G 100M
