[omarismail94]

Describe the bug

App crashes with the stack trace below when initialising the FhirOperator:

 java.lang.NoSuchMethodError: No static method getLogger(Ljava/lang/String;)Ljava/lang/System$Logger; in class Ljava/lang/System; or its super classes (declaration of 'java.lang.System' appears in /apex/com.android.art/javalib/core-oj.jar)

Component
Workflow Library

To Reproduce
Clone my repo:

https://github.com/omarismail94/android-fhir.git

Then checkout the branch: doesNotWorkFlow :

git checkout doesNotWorkflow

Launch the demo app onto a connected device or emulator:

./gradlew :demo:installDebug

the app crashes with the stack trace above.

The app I made is based on the Wiki guide: https://github.com/google/android-fhir/wiki/WFL%3A-Getting-Started

Expected behavior
I expect the app to load. I set the minSDK version to 28, after looking at Issue #1627 but that did not help.

Smartphone (please complete the following information):

• Device: Pixel 7

@vitorpamplona If you have a chance, can you look at this and let me know what I am missing? I feel Im missing something simple but I've been banging away at this for a couple of hours and can't find a solution

Thanks to @aditya-07 , I am able to resolve this issue. I have to add this block to my demo build file:

configurations {
  all {
    removeIncompatibleDependencies()
    forceHapiVersion()
  }
}

I see this block as well in the Workflow lib, why doesn't compiling the Workflow lib as a JAR include the dependencies that result from forceHapiVersion?
