Question
I'm encountering issues when trying to run any application in the Tizen Studio emulator (Samsung TV 4.0). When I select "Run as > Tizen TV Application", the execution fails with an error. The error occurs specifically when using a distributor certificate that contains one or more DUIDs.
Key observations:
- The application runs successfully when using a certificate without DUIDs
- The error only occurs when the active certificate has DUIDs
- I need to test with real devices, so I require a solution that allows signing with DUIDs

Answer
Problem Understanding
The issue stems from a known bug in Tizen Studio when using distributor certificates containing DUIDs for Samsung TV 4.0 emulator deployment. This prevents proper execution of applications in the emulator environment.
Solution Methods
-
Workaround for Emulator Testing:
- Create and use a Tizen certificate without DUIDs
- This allows successful deployment to emulators
- Note: This solution is only for emulator testing
-
Workaround for Real Device Testing:
- Use the Tizen Public certificate (without DUIDs) as the active certificate
- This has been reported to work for deploying to Tizen 4.0 real devices
-
Alternative Navigation in Emulator:
- If you can't find your app in the emulator:
- Click the Home button
- Press left to select 'More Options' icon
- Navigate to the 'Apps' menu to find your application
- If you can't find your app in the emulator:
Additional Tips
- Remember that TV emulators require remote-style navigation (using keyboard arrow keys) rather than mouse/touch input
- Consider reporting this issue through the official Tizen bug tracker if you need a permanent fix for DUID-signed certificates
- For emulator navigation issues, ensure you're using the correct input method (remote control simulation)
