Java compatibility : Using the android SDK from java

[joiskash]

While implementing com.google.android.fhir.FhirEngine in a java class, every function has an extra argument Continuation<? super Bundle> continuation that cannot be null. This maybe due to the suspend keyword. More details are available in this link.

Hi,

We are aware that the library is not very usable outside kotlin coroutines right now.

We plan to tackle it in the future by writing Java / RX wrappers (similar to AndroidX) once the library API becomes more stable.

Is this blocking you? If so, we can help unblock you by creating a wrapper that handles your use case instead of a generic one for now.

Ok thats alright. I have currently written a kotlin wrapper and it seems to be working. Im not sure if thats the right way though. The wrapper gets the application context as a parameter .

val coroutineScope: CoroutineScope
    get() {
      return MainScope() + CoroutineName(context.javaClass.simpleName)
    }

  fun updateFromJava( resourceToUpdate: Resource){
    coroutineScope.launch {
      fhirEngine.update(resourceToUpdate)
    }
  }

  fun searchFromJava(search: Search): List<Patient> {
    var searchResults: List<Patient> = listOf()

    runBlocking {
      searchResults =
        fhirEngine.search(
          search
        )
    }
    return searchResults
  }

Do let me know if there is a better way of doing this. Thanks!
