Moving to Threema Libre on a phone with Android App Support 10 (184.108.40.206 (Vanha Rauma)), I had to use the workaround documented here, to get the LED light blue for a new message.
- (Prerequisite): Developer mode, enabled, using ssh access and devel-su priviledges.
- Find the application identifier, using “top” and “ps -Af”:
- add the folloging lines in the file
Threema Libre;chat,chat_exists package:ch.threema.app.libre;chat,chat_exists
- restart device
It does not look to be a defect, but it seems that in general this is the file that controls if an android application can use SFOS LEDs for notifications.
Thanks for all hints in this thread!
