K-9 Mail crashes when I try to Send

[physkets]

As described, when I press 'Send', and choose K-9 Mail, it attempts to open it, but it crashed without any error message.

I am using the latest stable version of both, from F-Droid.

I am having problems reproducing this, using with K9-Mail both on my main phone (which could be a special case as I install directly to it via ADB, and my test phone, which is a Samsung Galaxy S3 - which is probably older than the yours as it runs Android 4.3. On an emulator running Android 5.1.1, with Gmail I do get a crash, but gmail crashes as soon as invoked anyway on there, probably because it is not logged in to Google.

Could you let me know your Android Version ?

I am using Android 9.0 (actually LineageOS 16.0). The crash is immediate, in that K-9 does not even appear.

Under an Android 9.0 emulator I see the same results, with a message

LocalFileProvider - openFile: fileLocation: /data/user/0/org.paladyn.mediclog/files/mediclog.txtis invalid followed by an exception in mediclog, followe by

The documentation for FileProvider says that it is no longer maintained an to migrate to using AndroidX:

A workaround for this issue has been tested on an emulator running Android 9.0, as well as Android 8.1 Workaround in release v0.2.7
