How to test in-app update API in android?

Question

I want to integrate flexible updates in my app. Here is my code:

fun checkForUpdates(){

    val appUpdateManager = AppUpdateManagerFactory.create(this)
    val appUpdateInfoTask = appUpdateManager.appUpdateInfo


    val listener = InstallStateUpdatedListener {

        if (it.installStatus() == InstallStatus.DOWNLOADED){

            val snackBar = Snackbar.make(parentLayout, "An update has just been downloaded.", Snackbar.LENGTH_INDEFINITE)
            snackBar.duration = 10000
            snackBar.view.setBackgroundColor(ContextCompat.getColor(this, R.color.colorPrimaryDark))
            snackBar.setActionTextColor(ContextCompat.getColor(this, R.color.white))
            snackBar.setAction("RESTART") {
                appUpdateManager.completeUpdate()
            }
            snackBar.show()
        }
    }


    appUpdateInfoTask.addOnSuccessListener { appUpdateInfo->
        if (appUpdateInfo.updateAvailability() == UpdateAvailability.UPDATE_AVAILABLE && appUpdateInfo.isUpdateTypeAllowed(AppUpdateType.FLEXIBLE)){
            appUpdateManager.registerListener(listener)
            appUpdateManager.startUpdateFlowForResult(
                appUpdateInfo,
                AppUpdateType.IMMEDIATE,
                this,
                UPDATE_REQUEST_CODE)

        }
    }
}

I am facing problem with testing it. I tried decreasing my build version number but it doesn't seems to work.

As noted in the docs:

Make sure that the app that you are testing in-app updates with has the same application ID and is signed with the same signing key as the one available from Google Play.
Make sure the account you’re using has downloaded your app from Google Play at least once before using the account to test in-app updates
Because Google Play can only update an app to a higher version code, make sure the app you are testing as a lower version code than the update version code.
Make sure the account is eligible and the Google Play cache is up to date.
