[digiKam-users] Success in importing pictures from Android mobile phone

[kaizubg at gmail.com]

Hi digiKammers,

I want to report that I have been able to connect digiKam with my
Android mobile phone via USB cable and to download images to my laptop.
Here is a screendump of this:

https://drive.google.com/file/d/1q-zcGo7nxRpUWZmcfLMl3_7f0wAhs-1y/view?usp=share_link

The trick is to use Rapid Photo Downloader (version 0.9.33) to
initialize communication between the to the mobile phone. After this
digiKam functions  correcty. 

My environment is digiKam (7.9.0 AI) on Fedora 37 Linux and Gnome 43.1.
and my mobile phone is a HMD Global Nokia X30, Android 12.

And here a longer description of my workaround:

1. Connected my mobile phone with the USB cable and enabled the use of
USB connection in the options of the phone. As a result I was able to
navigate to the DCIM folder with the file manager.

2. Started digiKam and started the import dialog. digiKam had already
detected automatically the phone. The dialog showed an error message of
connection failure. The Retry button had no effect.

Screen dump from the situation:

And the corresponding part of the trace file:

3. Left digiKam in the background. Started Rapid Photo Downloader.
Photos on the phone are shown in the UI of RPD. Left PRD in the
background.

4.  Back to digiKam and pushed the Refresh button. Voila! digiKam
import dialog starts to scan images from the folders of the phone!

This is also documented in the trace file:

5. After a lenghty while the tumbnails were also generated. I was able
execute the download successfully.

My finding was just pure chance. I fiddled around with the different
applications after my recent OS upgrade. There is also no guarantee
that this workaroud works in other environments or constellations. 

I hope Guilles or others may find something usefull of this finding or
to give a more in-depth technical explanation. Hope also that digiKam
can do this in future without the help of RPD.

Cheers Kai

superhappy digiKammer
