无法在Android中获得广告ID提供商

Question

我想获取我的应用的广告ID，但没有成功。

import androidx.ads.identifier.AdvertisingIdClient;
import androidx.ads.identifier.AdvertisingIdInfo;

public class addUtilsJava extends AsyncTask<Context, String, String> {

    static String TAG = "addUtilsJava";


    private String getIdThread(Context context) {

        AdvertisingIdInfo adInfo = null;
        try {
            adInfo = AdvertisingIdClient.getAdvertisingIdInfo(context).get();

        } catch (Exception exception) {
            exception.printStackTrace();
        }
        if (adInfo != null) {
            final boolean isLAT = adInfo.isLimitAdTrackingEnabled();
            return adInfo.getId();
        }
        return null;
    }
    @Override
    protected String doInBackground(Context... contexts) {
        return getIdThread(contexts[0]);
    }
    @Override
    protected void onPostExecute(String s) {
        super.onPostExecute(s);
        if (s != null)
            Log.d(TAG, s);
    }
}

它抛出异常提示我androidx.ads.identifier.AdvertisingIdNotAvailableException: No Advertising ID Provider available。我试过2手机和模拟器都具有相同的结果。

提前致谢

ps：我检查了android doc中提供的解决方案，但对我不起作用https://developer.android.com/training/articles/ad-id
，我宁愿有一个不需要依赖性的解决方案

试试这个代码..为我工作..

import com.google.android.gms.ads.identifier.AdvertisingIdClient;
import com.google.android.gms.common.GooglePlayServicesNotAvailableException;
import com.google.android.gms.common.GooglePlayServicesRepairableException;
import android.widget.Toast;
public class MainActivity extends AppCompatActivity {
 @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.activity_main);

AsyncTask<Void, Void, String> task = new AsyncTask<Void, Void, String>() {
                    @Override
                    protected String doInBackground(Void... params) {
                        AdvertisingIdClient.Info idInfo = null;
                        try {
                            idInfo = AdvertisingIdClient.getAdvertisingIdInfo(getApplicationContext());
                        } catch (GooglePlayServicesNotAvailableException e) {
                            e.printStackTrace();
                        } catch (GooglePlayServicesRepairableException e) {
                            e.printStackTrace();
                        } catch (IOException e) {
                            e.printStackTrace();
                        }
                        String advertId = null;
                        try{
                            advertId = idInfo.getId();
                        }catch (NullPointerException e){
                            e.printStackTrace();
                        }

                        return advertId;
                    }

                    @Override
                    protected void onPostExecute(String advertId) {
                        Toast.makeText(getApplicationContext(), advertId, Toast.LENGTH_LONG).show();
                    }

                };
                task.execute();

}

}

build.gradle 添加依赖项

dependencies {
        implementation 'com.google.android.gms:play-services-ads-lite:18.1.1'
}
