5 years ago (trying to help do some legwork) - it appears that modern Android now uses the mime type from RFC 7763 text/markdown, which I am not seeing in the Markor AndroidManifest.xml. The Android mappings being used are located here now:
- https://android.googlesource.com/platform/libcore/+/master/luni/src/main/java/libcore/net/mime.types#744
- https://android.googlesource.com/platform/libcore/+/master/luni/src/main/java/libcore/net/android.mime.types
These are pulled in from the MimeTypeMap and parsed, so if we add that it should help. The Editor project is accepting text/* which makes sense why it works -- the Android subsystem is not sending the file as type text/plain but as text/markdown, so Markor doesn't get triggered as it's not built to accept that mime type (that I can tell, not an android coder :) ).
I also managed to find another link that shows using a +extension method to a mime type is pretty common (?), he shows his solution to read XML files was <data android:mimeType="application/xhtml+xml" /> (adding the +xml after the type) which may or may not help here, possibly adding the text/plain+md mapping would be enough. I think that would at least allow the default Google apps to show Markor as an intent receiver to get started... hope this helps!

Description
I'm having problems with consistent and reliable file sending into Markor, I've tried to reproduce this in several ways with different sending apps. In general, it feels like Markor has trouble receiving file intents sometimes, while other editors can receive them fine. I'm not sure where the bugs lie, I realize that they may be with the other apps so just trying to gather information.
I first added Editor, a very basic open source editor which seems to receive the file intents from all the below OK (except LabCoat) as an A / B test against Markor at the same time.
test.mdto my phone as an attachment and open it in the stock GMail app, the only option to open the file as a share or save is Editor - Markor doesn't even register as a receiver from GMail for *.md it appears?test.mdto Downloads, then using the "Files" app (built-in basic file app that comes with Android9/Pixel2) when choosing "Open with..." the option for Markor is not present, but Editor is (as well as FX Textedit and FX Text Viewer, part of FX File Manager app)filemanager_doesnot_supply_required_data__appspecificcode path. As the Editor source is also open, this was a very good A / B test - Markor should be able to receive the same file as Editor did?The only counter-example of "seems to work right" is when using FX File Explorer, however this app uses a different method than most others (you have to choose "Open as..." then select a MIME type
text/plain, then choose the app to receive - both Markor and Editor receive the file intent fine this way). This app is not open source and has different behaviour traits - interesting, but maybe not useful for this debugging.Perhaps if nothing else, figuring out why another open source editor (Editor) receives the file intents OK from "GMail" and "Files" stock Android/Google apps would be a clue as to what's going on with Markor's basic file-opening issues. Green Git Client doesn't seem to have source to look at yet (it's alpha), but is an interesting "why doesn't this work either with Markor?". LabCoat's source seems like they copied it from another project so it's an outlier here. Thanks for listening!
