Shared log can be too large

[Helium314]

How to Reproduce Manage to accumulate a large amount of log messages (e.g. by being very active), then go to logger, select an early start date and click share. This may result in android.os.TransactionTooLargeException.

Expected Behavior Working log share. Maybe truncate the log if necessary, or write to a file instead.

Versions affected Probably all since addition of the logger.

Truncate to only the newest or only the oldest? What magnitude of numbers are we talking?

[Helium314]

I would say truncate to the newest, and maybe show a toast to clarify. Or check the size beforehand, and ask the user to use filters to reduce the size.

What magnitude of numbers are we talking?

I got a crash report where the log couldn't be shared because the size was 3.6 MB.

According to a quick research, if the data passed in an Intent is below 500 kB it should be safe.

Assuming an average log size of 100 bytes, we have around 50,000 lines.

According to the documentation, it is also possible to not send the text directly but put it in some file and have the link to it in there. This would remove that restriction. Something with EXTRA_STREAM...

Just adding @neonowy to the conversation

I've tried to share a log with some 9k lines/entries from the StreetComplete, and it crashed:
