<![CDATA[Logs from app crash]]>Hi,

I am trying to see what is happening when one of my applications crashes on Volla phone 22. There is nothing when using log viewer. I also tried searching through other log files in terminal app.

Then I found this web page: https://ubports.com/en/blog/ubports-news-1/post/logviewer-3093. There I read this point:

"crash logs: /var/crash (in order for these logs to generate you need to activate Application crashes and errors at the following location: System settings > Security and privacy)"

But I do not see any such settings. Is there some way how to enable /var/crash logs in current version of Ubuntu Touch?

Many thanks
Andrej

I understand and respect that people have their lives. Also I know how it is sometimes hard to find time and energy for hobby projects. I appreciate all replies you sent me.

And I am happy you got it sorted in the end. Looking forward to seeing your app in the Open Store.

It was kind of a stupid mistake. I had a wrong click framework (16.04). After changing to 16.04.5 it works just fine.

The repo is here: https://gitlab.com/andrisk/hnefatafl and the xenial branch is the one I used. But I have seen the crash only on the Volla phone 22 so far.

Using clickable desktol it works without a problem. After crash there is only this message in the log:

file offset for the library "/vendor/lib64/hw/gralloc.default.so" >= file size: 0 >= 0

It is the same if I build rust template application and try to run it on the phone. But I am not sure if the message is relevant because I found the same message in logs of applications that are not crashing.

If it does and only crashes on the device you might be missing app armor permissions. Which ones depends on what your app is doing.

You need to enable developer mode (Settings > About > Developer mode) so that they will be retained.

I am building app hnefatafl.andrisk and it always crashes when loading on Volla phone 22 with Ubports 16.04 OTA-25. Update to 20.04 might solve this, but I still want to know why it does not work. I also tried to build Rust template app for 16.04 and it crashes on Volla phone 22 as well.

Is this for debugging one app that you are building ?
