Android Studio 使用官方代码段获取广告 ID

Question

has anyone managed to get the android advertisement Id in an app using the official snippet 

https://developer.android.com/training/articles/ad-id

I couldn't make this snippet to work in my app.

I have added the:
'''
dependencies {
  implementation 'androidx.ads:ads-identifier:1.0.0-alpha01'

  // Used for the calls to addCallback() in the snippets on this page.
  implementation 'com.google.guava:guava:28.0-android'
}
'''
And Gradle synced without any problems.

The code that's problematic is:   

'''java

     ListenableFuture<AdvertisingIdInfo> advertisingIdInfoListenableFuture = AdvertisingIdClient.getAdvertisingIdInfo(getApplicationContext());
            Futures.addCallback(advertisingIdInfoListenableFuture,
                    new FutureCallback<AdvertisingIdInfo>() {                        
                        @Override
                        public void onSuccess(@NullableDecl AdvertisingIdInfo result) {
                            String myAdvertisementId = result.getId();
                        }

                        @Override
                        public void onFailure(Throwable t) {

                        }
            });

''' 错误是：错误：Futures 类中的方法 addCallback 不能应用于给定类型；
需要：ListenableFuture、FutureCallback、Executor

Supposedly it asks for executor but the official snippet is without one

Answer 1

如果您查看此处的文档，kotlin 代码段将传递一个Executor作为第三个参数（java 示例遗漏了一个）。 所以你应该在java中做同样的事情：

Futures.addCallback(advertisingIdInfoListenableFuture,
                    new FutureCallback<AdvertisingIdInfo>() {                        
                        @Override
                        public void onSuccess(@NullableDecl AdvertisingIdInfo result) {
                            String myAdvertisementId = result.getId();
                        }

                        @Override
                        public void onFailure(Throwable t) {

                        }
            }, Executors.newSingleThreadExecutor());
