Android: Encryption support silently breaks

[krille-chan]

Description

Essential encryption featues seem to be unavailable on my Android device, it looks like FluffyChat enters a failure mode. After login, I am not asked to verify the device, and in the Settings -> Security page, the menu items for my public key and key backup are simply missing, I only see the points “Ignored users”, “Change password” and “Password recovery”. On the in-browser version of FluffyChat on my desktop everything works as expected though. With FluffyChat Android I can't read any of the encrypted chats and FluffyChat sends unencrypted messages even into encrypted chat rooms.

Furthermore, I cannot verify the FluffyChat Android session from Element. Element desktop doesn't list the session in the verification panel, although I can see it in the session management setttings. Element Android lists the session, but says “No cryptographic information available” for my FluffyChat Android session, so I can't start the verification there either.

Sadly, logcat doesn't seem to provide any useful information:

$ adb logcat | grep flutter
W/linker  (21888): libflutter.so: unused DT entry: type 0x6ffffef5 arg 0x2098
W/linker  (21888): libflutter.so: unused DT entry: type 0x6ffffffe arg 0x2038
