SettingsClient的位置请求始终获得RESULT_CANCELED

Question

在获取当前位置流时，我正在使用SettingsClient根据当前LocationRequest来检查是否满足位置设置。目前，我的优先级设置为HIGH_ACCURACY，这需要不惜一切代价启用GPS。

        fusedLocationProviderClient = LocationServices.getFusedLocationProviderClient(this);
        settingsClient = LocationServices.getSettingsClient(this);
        locationRequest = LocationRequest.create()
                .setPriority(LocationRequest.PRIORITY_HIGH_ACCURACY)
                .setInterval(500)
                .setFastestInterval(500);
        LocationSettingsRequest.Builder builder = new LocationSettingsRequest.Builder();
        builder.addLocationRequest(locationRequest);
        locationSettingsRequest = builder.build();

现在，当我调用给它提供侦听器的SettingsClient.checkLocationSettings（）时，

settingsClient.checkLocationSettings(locationSettingsRequest)
                .addOnCompleteListener(this)
                .addOnFailureListener(this);

它属于onFailure（），在这种情况下，github上的google官方示例采用以下方法；

检查在onFailure（）中接收到的异常的状态码（如果它是LocationSettingsStatusCodes.RESOLUTION_REQUIRED），然后调用startResolutionForResult（），它允许我们启用GPS，这将等待使用onActivityResult的结果。

    @Override
    public void onFailure(@NonNull Exception e) {

        int statusCode = ((ApiException) e).getStatusCode();
        switch (statusCode) {
            case LocationSettingsStatusCodes.RESOLUTION_REQUIRED:

                try {
                    // Show the dialog by calling startResolutionForResult(), and check the
                    // result in onActivityResult().
                    ResolvableApiException rae = (ResolvableApiException) e;
                    rae.startResolutionForResult(LocationActivity.this, REQUEST_CHECK_SETTINGS);
                } catch (IntentSender.SendIntentException sie) {
                    showLocationError();
                }
                break;
            case LocationSettingsStatusCodes.SETTINGS_CHANGE_UNAVAILABLE:
                showError();
                break;
        }
    }

问题是，每当调用设置客户端的onFailure并调用startResolution时，它始终属于Activity.RESULT_CANCELED情况。但这很奇怪，尽管这已取消，但GPS却在几秒钟内打开。

@Override
protected void onActivityResult(int requestCode, int resultCode, Intent data) {
    switch (requestCode) {
        // Check for the integer request code originally supplied to startResolutionForResult().
        case REQUEST_CHECK_SETTINGS:
            switch (resultCode) {
                case Activity.RESULT_OK:
                    // fetch location here
                    break;
                case Activity.RESULT_CANCELED:
                    // this is called immediately first time 
                    // and second time even when GPS is on
                    break;
            }
            break;
    }
}

在打开GPS后，当我执行相同的操作（获取当前位置）时，SettingsClient仍会调用onFailure，尽管打开了GPS，结果始终是Activity.RESULT_CANCELED。

问题在Redmi 4X和Motorola Droid Turbo上再现

还有其他将SettingsClient与这种方法结合使用并面临任何类似问题的人吗？

这是我关注的官方样品

此错误也已在GitHub官方问题页面上报告
