[BUG?] AVNC crashed on an Android 6.0 tv box

[fish4terrisa-MSDSM]

I've hacked my tv box and flashed aosp firmware. And I installed AVNC on it so that I can use it to behave as a second screen for my linux pc. However, when I connect to my vnc server at the first time, it (seems that it )cannot load the first time tips successfully and crashed. Here's the log:

Does anyone know how to fix it? (Selinux is set to Permissive status) (I have the device rooted. So any methods which need root accesses are welcomed)

Hi @fish4terrisa-MSDSM, which version are you using? v2.5.2 was released yesterday with fix for this issue.

[fish4terrisa-MSDSM]

Thank you! I have already tried it and it really worked! I'm using an older release.
