Roboelectic test in android throwing java.lang.NoSuchFieldError: tag_on_apply_window_listener

I'm trying to run a simple unit test using Roboelectric however on trying to build an Activity , I'm getting the following error :

java.lang.Exception: Main looper has queued unexecuted runnables. This might be the cause of the test failure. You might need a shadowOf(getMainLooper()).idle() call.

Culprit seems to be this line : java.lang.NoSuchFieldError: tag_on_apply_window_listener

My test file is pretty straighforward :

@Test
  fun testQuizHomeActivity(){
    val context: Context = RuntimeEnvironment.application.getApplicationContext()
    FirebaseApp.initializeApp(context)
    val intent: Intent = Intent()
    intent.putExtra("userId", "")
    intent.putExtra("userName", "userName")
    intent.putExtra("upcomingVQuiz", "upcomingVQuiz")
    intent.putExtra("source", "source")
    shadowOf(getMainLooper()).idle();
    val quizHomeActivity = Robolectric.buildActivity(MainQuizActivity::class.java, intent).create().get()
    Assert.assertNotNull(activity)
  }

The other tests are working without an issue.

Are you using gradle setting like

testImplementation "androidx.core:core-ktx:+"  ?

If so, try using fixed verision like 1.3.2. I can solve same issue by that. It seems ViewCompat's implementation has been changed.
