Lrm Android: How to reliably trigger auto-import (from other app)?

[fimagena]

Hi - I'm the author of an Android photo app and would like Lightroom mobile to automatically import DNG-files produced by my app. Unfortunately, right now, I am observing the following behaviour

- My app writes a DNG (or moves it) to a folder watched by Lightroom (e.g., "~/Pictures") - no reaction/import from the Lightroom mobile app

- If I rename the DNG with a file explorer (doesn't matter to what) in the same directory, Lightroom mobile suddenly recognises the file and automatically imports it

I have confirmed that the inotify events produced by my app and the file explorer are identical. I assume Lrm uses a different mechanism to watch directories for new files. This is tested on a Samsung S8 but I have gotten similar reports for other handsets as well.

If there are any of the Lrm Android devs present here, would you mind commenting on...

- ...the logic Lrm for Android uses to recognise new picture files created

- ...how I can adapt my app, so Lrm will automatically import its outputs

Many thanks!

Ok, figured it out myself: In the newer versions, Lrm for Android doesn't watch the various directories itself anymore but relies on Android's MediaScanner to pick up any newly created images. Hence, when creating a new image, it is necessary to have Android trigger an index-update for Lightroom to import the picture.

But what if Android does not recognize dng or other raw formats as media?
