Google Safe Browsing api result is not the same as online result

Question

I use Google Safe Browsing api doc to let My android application can check URL whether is safe or not.

https://developer.android.com/training/safetynet/safebrowsing?hl=zh-cn

But when I send valid phish URL, there is no wrong with message.

I use this URL to check the website online:

https://transparencyreport.google.com/safe-browsing/search?url=

My test URL(valid Phish website):

http://online-podpora.cc/

The online result(It will display unsafe website):

https://transparencyreport.google.com/safe-browsing/search?url=http:%2F%2Fonline-podpora.cc%2F

But my application message display:

Want to check URL is：
http://online-podpora.cc/
null
SafetyNet response sucessfully!
There is no threat in this website.

My build.gradle:

implementation 'com.google.android.gms:play-services-safetynet:18.0.1'

The code:

I have Initialized the API in onResume():

@CallSuper
    @Override
    protected void onResume() {
        super.onResume();
        _vaultManager.setBlockAutoLock(false);
        Thread thread = new Thread(){
            public void run(){
                try {
                    Tasks.await(SafetyNet.getClient(getApplicationContext()).initSafeBrowsing());
                } catch (ExecutionException e) {
                    System.out.println(e.getMessage());
                    e.printStackTrace();
                } catch (InterruptedException e) {
                    System.out.println(e.getMessage());
                    e.printStackTrace();
                }
            }
        };
        thread.start();

    }

     //Use SafetyNet
                System.out.println("Want to check URL is：");
                System.out.println(URL_text);
                SafetyNet.getClient(this).lookupUri(URL_text, myAPIKEY,
                        SafeBrowsingThreat.TYPE_POTENTIALLY_HARMFUL_APPLICATION,
                        SafeBrowsingThreat.TYPE_SOCIAL_ENGINEERING)
                        .addOnSuccessListener(this,
                                new OnSuccessListener<SafetyNetApi.SafeBrowsingResponse>() {
                                    @Override
                                    public void onSuccess(SafetyNetApi.SafeBrowsingResponse sbResponse) {
                                        // Indicates communication with the service was successful.
                                        // Identify any detected threats.
                                        System.out.println("SafetyNet response sucessfully!");
                                        if (sbResponse.getDetectedThreats().isEmpty()) {
                                            // No threats found.
                                            System.out.println("There is no threat in this website.");
                                        } else {

                                    // to be called again due to an internal error.
                                } else {

                                    // A different, unknown type of error occurred.
