Android – Logcat crashes with error: unexpected EOF

androidandroid-logcat

I’m running some lengthy calculations and something goes wrong quite late. I tried using breakpoints, but with no success so far. So I put into the loop a Log.d to monitor…

But quite soon, Logcat crashes with:

02-08 16:35:42.820 2936-3402/com.nohkumado.geneticsolving.full D/BaseC: 
    norm:BC sq:49.0 dis:0.0 con:50.0/BC sq:56.0 dis:4.0 con:94.0=1.4069148936170213

    read: unexpected EOF!

    --------- beginning of crash

and I need to restart the studio to get Logcat running again.

I looked if I could find some setting for the buffer size for Logcat, but so far I’ve found nothing. What can be done?

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.

  1. 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.
