SUMMARY

On virtually any TLS error, including sending an invalid/corrupted certificate or just bailing during the handshake, the Android app will crash.


STEPS TO REPRODUCE
1. Setup two devices with a KDE Connect client, at least one with the Android app
2. Attempt to connect with a faulty certificate or just close the connection during authentication
3. 

OBSERVED RESULT

kdeconnect-android crashes, usually restarting and crashing again when the device attempts to handshake again

EXPECTED RESULT

Probably the connection should close, or ideally prompt the user about a possible fraudulent connection attempt.

ADDITIONAL INFORMATION

I reproduced this with GSConnect, but no doubt it's possible to create this issue with kdeconnect-kde. It's rare to happen in the wild, but tends to happen when users do silly things like change their hostname or try copy settings between machines.
