• make WorkoutSession and WorkoutDto one class
  Whats the difference between WorkoutSession and WorkoutDto? Are both needed? If so, why?
  ok I understand 🤔 but I think this is kinda confusing. I would merge these 2 together because it represents the same object but the session have just a few extra states.
  That way consumer of this object (or within the app) you firstly check in what State is the WorkoutDto and based on that you can/cant read it's properties.
  If you are worried that consumers of this object would call e.g. Resume, End and other methods, then make them internal(only this library can call them).
  That way you simplify working with this object....because there will be only one. And it will be uniform.

• You are saying I cant do something like GetActiveSession in those libraries...even though I started that session in the app before?

  I just wanted to add a note in case you all weren't aware.
  The DataOrigin on Android is not writeable.
  You can set it and send it but Android will always overwrite it with the package name of the app that is writing the data. I just ran a test trying to write "com.fitbit.FitbitMobile" in an attempt to spoof steps from a fitbit device but the origin when read back out was my app's package name that inserted the data.

Status Check (2026-04-03)

All 6 checked items are confirmed done.

For the unchecked items:

Item	Status
Merge WorkoutSession and WorkoutDto	Still separate classes with conversion extensions between them
GetActiveSession	✅ Implemented — GetActive() exists on IHealthWorkoutService, works on both platforms. Can be checked off.
Reflection	Still present — JavaReflectionHelper.cs for Android Java/Kotlin interop, plus typeof().Name switches in MetricDtoExtensions and HealthDataTypeExtensions
Extract reflection	Partially done — Android reflection centralized in JavaReflectionHelper.cs, but C# type-dispatch reflection still inline
DataOrigin not writeable on Android	No documentation or handling of the Android limitation (overwrites DataOrigin with app package name)
Get rid of statefulness of WorkoutSession	WorkoutSession still has mutable Pause(), Resume(), End() methods
