在Google GDPR同意sdk中显示非个性化广告的问题

Question

我在我的项目中实施了谷歌同意sdk，直到我想在用户离开欧洲经济区时正常展示广告，并在他进入欧洲经济区时显示个性化或非个性化广告。但更改后，代码不会给我任何结果。

这是我的代码：

public class MainActivity extends AppCompatActivity {

  private String TAG = this.getClass().getSimpleName();
  ConsentForm form;
  TextView textView;
  private AdView mAdView;

  @Override
    protected void onCreate(Bundle savedInstanceState) {
    super.onCreate(savedInstanceState);
    setContentView(R.layout.activity_main);

    MobileAds.initialize(this, "ca-app-pub-xxxxxxx");

    showPersonalizedAds();

    textView = findViewById(R.id.simo2);

    checkForConsent();
 ConsentInformation.getInstance(MainActivity.this).setDebugGeography(DebugGeography.DEBUG_GEOGRAPHY_EEA);
}

private void checkForConsent() {
    ConsentInformation consentInformation = ConsentInformation.getInstance(MainActivity.this);
    String[] publisherIds = {"pub-xxxxx"};
    ConsentInformation.getInstance(MainActivity.this).addTestDevice("xxxxxx");
    consentInformation.requestConsentInfoUpdate(publisherIds, new ConsentInfoUpdateListener() {
        @Override
        public void onConsentInfoUpdated(ConsentStatus consentStatus) {
            // User's consent status successfully updated.
            switch (consentStatus) {
                case PERSONALIZED:
                    Log.d(TAG, "Showing Personalized ads");
                    showPersonalizedAds();
                    break;
                case NON_PERSONALIZED:
                    Log.d(TAG, "Showing Non-Personalized ads");
                    showNonPersonalizedAds();
                    break;
                case UNKNOWN:
                    Log.d(TAG, "Requesting Consent");
                    if (ConsentInformation.getInstance(getBaseContext())
                            .isRequestLocationInEeaOrUnknown()) {
                        requestConsent();
                    } else {
                        showPersonalizedAds();
                    }
                    break;
                default:
                    break;
            }
        }

        @Override
        public void onFailedToUpdateConsentInfo(String errorDescription) {
            // User's consent status failed to update.
        }
    });

    // on the onCreate
}

private void requestConsent() {

    URL privacyUrl = null;
    try {
        // TODO: Replace with your app's privacy policy URL.
        privacyUrl = new URL("http://qisasprivacy.blogspot.com/");
    } catch (MalformedURLException e) {
        e.printStackTrace();
        // Handle error.
    }
    form = new ConsentForm.Builder(MainActivity.this, privacyUrl)
            .withListener(new ConsentFormListener() {
                @Override
                public void onConsentFormLoaded() {
                    // Consent form loaded successfully.
                    Log.d(TAG, "Requesting Consent: onConsentFormLoaded");
                    showForm();
                }

                @Override
                public void onConsentFormOpened() {
                    // Consent form was displayed.
                    Log.d(TAG, "Requesting Consent: onConsentFormOpened");
                }

                @Override
                public void onConsentFormClosed(
                        ConsentStatus consentStatus, Boolean userPrefersAdFree) {
                    // Consent form was closed.
                    Log.d(TAG, "Requesting Consent: onConsentFormClosed");
                    if (userPrefersAdFree) {
                        // Buy or Subscribe
                        Log.d(TAG, "Requesting Consent: User prefers AdFree");
                    } else {
                        Log.d(TAG, "Requesting Consent: Requesting consent again");
                        switch (consentStatus) {
                            case PERSONALIZED:
                                showPersonalizedAds();break;
                            case NON_PERSONALIZED:
                                showNonPersonalizedAds();break;
                            case UNKNOWN:
                                showNonPersonalizedAds();break;
                        }

                    }
                }

                @Override
                public void onConsentFormError(String errorDescription) {
                    // Consent form error.
                    Log.d(TAG, "Requesting Consent: onConsentFormError. Error - " + errorDescription);
                }
            })
            .withPersonalizedAdsOption()
            .withNonPersonalizedAdsOption()
            .build();
// load the form so we can call .show on it after
    form.load();

}

private void showPersonalizedAds() {
    AdView mAdView = findViewById(R.id.adView);
    AdRequest adRequest = new AdRequest.Builder()
            .addTestDevice("xxxxxx") // Todo: Remove in Release build

}

private void showForm() {

    }
    if (form != null) {

}
