Question
I'm having an issue with Tizen Studio while trying to run my first "Hello Tizen" native application. The application runs fine on the emulator, but I can't run it on my physical device because the Device Manager fails to open. When I attempt to launch it, I receive the following error message: "Unexpected exception occurred. Exception: Exception in application start method"
Environment details:
- Java version: Oracle Java 8
How can I resolve this issue?
