Play Core In-App Review API not showing the Review Activity

Question

I\'m trying to utilize the Review API (Play Core library 1.8.0) from Google which was just released yesterday. See https://developer.android.com/guide/playcore/in-app-review

I just want to share the code that is working reliably today (2020-09-03). It was essentially copied from the official document

ReviewManager manager = ReviewManagerFactory.create(activity);
Task request = manager.requestReviewFlow();
request.addOnCompleteListener(task -> {
    try {
        if (task.isSuccessful()) {
            // We can get the ReviewInfo object
            ReviewInfo reviewInfo = task.getResult();
            Task flow = manager.launchReviewFlow(activity, reviewInfo);
            flow.addOnCompleteListener(task2 -> {
                // The flow has finished. The API does not indicate whether the user
                // reviewed or not, or even whether the review dialog was shown. Thus, no
                // matter the result, we continue our app flow.
                utility.logMessageAsync(activity, "In-app review returned.");
            });
        } else {
            // There was some problem, continue regardless of the result.
            goToAppPage(activity);
        }
    } catch (Exception ex) {
        utility.logExceptionAsync(activity, "Exception from openReview():", ex);
    }
});

It was tested with internal app sharing on a Android 10. It never failed to show the review dialog.
