问题
I am trying my hand at Tizen TV App Development and every time i try to launch even the basic template app, I get an error saying: "Step SDB shell handle failed" And when I click details:
step SDB shell handle failed
Failed to step SDB shell handle 'ls /usr/bin/xwalk-launcher > /tmp/null.deployer 2>&1; echo $? ' command` operation (Return Code:31)
sdb command rejected exception
It would be such a huge help if someone here could help out. I checked everywhere. Samsung Developer Forums, the Development Guideline, but couldn't find the solution

I hope that can be useful for everyone.

So I found the solution, to anyone who wants to know.
Its because of improper security certification. Just follow the steps on this site and you should be good to go! https://www.samsungdforum.com/TizenGuide/tizen3531/index.html

I was running into this on MacOS. The solution is to create and import an author certificate via Tizen Studio.
Directions for doing this can be found here
回答4:
Try to disable Firewall and install certificate manager and app development from tizen update manager
