即使单击确定，LocationSettingsRequest 也会向 onActivityResult 返回 0

Question

我正在使用以下代码显示弹出窗口以打开位置

        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder()
            .addLocationRequest(mLocationRequest);
    SettingsClient client = LocationServices.getSettingsClient(getActivity());
    Task<LocationSettingsResponse> task = client.checkLocationSettings(builder.build());

    task.addOnSuccessListener(getActivity(), new OnSuccessListener<LocationSettingsResponse>() {
        @Override
        public void onSuccess(LocationSettingsResponse locationSettingsResponse) {
            // All location settings are satisfied. The client can initialize
            // location requests here.
            // ...
            getUserLocation();
        }
    });

    task.addOnFailureListener(getActivity(), new OnFailureListener() {
        @Override
        public void onFailure(@NonNull Exception e) {
            int statusCode = ((ApiException) e).getStatusCode();
            Log.d("AMOD", "onFailure " + statusCode);
            switch (statusCode) {
                case CommonStatusCodes.RESOLUTION_REQUIRED:
                    // Location settings are not satisfied, but this can be fixed
                    // by showing the user a dialog.
                    try {

                        ResolvableApiException resolvable = (ResolvableApiException) e;
                        resolvable.startResolutionForResult(getActivity(),
                                REQUEST_CHECK_SETTINGS);
                    } catch (IntentSender.SendIntentException sendEx) {
                        // Ignore the error.
                    }
                    break;
                case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                    // Location settings are not satisfied. However, we have no way
                    // to fix the settings so we won't show the dialog.
                    break;
            }
        }
    });

以下是代码 它显示如下弹出窗口

但有时即使用户点击 Ok 我也会得到响应 0 即 RESULT_CANCEL 在将播放服务更新到 16.0.0 后会发生这种情况

在 google issuetracker 上报告了这个错误，下面是关于它的更多详细信息的链接

我只尝试了大约 50 次来重现这个，我总是得到代码 -1（运行 Android Pie 的 Pixel 3）。但我在运行 Oreo 的 Nexus 5x 上大约有一半的时间为 0。

我无法准确地找出你做错了什么，但这是我制作的一个示例项目，它做同样的事情并且每次都能正常工作：
