K-9 Mail has controllable debug logging. Users can activate logging to help diagnosing problems and errors.


Step 1: Activate Debug Logging in K-9 Mail

At the accounts screen of K-9 Mail press the menu button, then choose "Settings". Under the heading "Debugging" check the "Enable debug logging" checkbox. Hit the back button twice to save the changes.

If K-9 is crashing or you otherwise can't get to the settings screen, don't worry about about enabling debug logs.

Step 2: Trigger error

Do whatever causes the problem/error.

Step 3: Get Debug Log

To fetch the debug log you have to attach the device to your PC and use the tool adb from the Android SDK:

  1. Follow these instructions to install adb and to connect your device.

  2. Find the process ID of K-9 Mail:

    In Linux / Mac

     adb shell ps -A | grep k9

    In Windows

     adb shell ps -A | findstr k9

    The output will be similar to:

    u0_a153       5191   587 4468612 112380 SyS_epoll_wait      0 S com.fsck.k9

    In this example the PID is 5191

  3. To capture the debug log in a file named k9-log.txt, enter the command:

    adb logcat -d --pid=<PID> > k9-log.txt

Step 4: Create an Issue in our Bug Tracker

To be able to fix your problem we need to know about it. Please create a new issue in our bug tracker. Attach a copy of the debug log you just created.

It's ok to remove your password from the debug log. Other than that, please give us as much of the log as you possibly can.

Important: Include the exact version number of your installed K-9 Mail in the bug report. Read GetVersionNumber if you need help on finding out which version of K-9 you're running.
