I'm trying to use Samsung sample SimpleHealth for retrieving data from Samsung Health app, but when I give the permission to get StepCount data, I get a weird error:

Faced same error. You need to add dev access code. Follow Prerequisites section carefully from this page https://developer.samsung.com/health/android/sample/simple-health.html
