Retrieving Information about the Ad Response

For debugging and logging purposes, successfully loaded ads provide a ResponseInfo object. This object contains information about the ad it loaded. Each ad format class has a method to get the response info. On interstitial ads for example, use the getResponseInfo() method.

Methods on the ResponseInfo object include:


Returns the list of AdapterResponseInfo containing metadata for each adapter included in the ad response. Can be used to debug the waterfall mediation and bidding execution.

For each ad network, AdapterResponseInfo provides the following methods:

Method Description
getAdError Gets the error associated with the request to the network. Returns null if the network successfully loaded an ad or if the network was not attempted.
getAdapterClassName Gets a class name that identifies the ad network.
getCredentials Gets the network configuration set on the Ad Manager UI.
getLatencyMillis Gets the amount of time the ad network spent loading an ad. 0 if the network was not attempted.

Querying these properties lets you drill into the outcome of a waterfall mediation and bidding for each ad request.


Returns the AdapterResponseInfo corresponding to the adapter that was used to load the ad. Returns null if the ad failed to load. See the methods provided by AdapterResponseInfo above.


The class name of the ad network that fetched the current ad. Values that can be returned from this method include:

Ad Source Class name
Google Ads
Rewarded Custom events Your custom event's class name
All other custom events
Mediation The mediation adapter's class name


The response identifier is a unique identifier for the ad response. This identifier can be used to identify and block the ad in the Ads Review Center (ARC).

Sample code

Here is a sample snippet from an AdListener callback implementation:


public void onAdLoaded() {
    ResponseInfo responseInfo = bannerAdView.getResponseInfo();
    Log.d(TAG, responseInfo.toString());

public void onAdFailedToLoad(LoadAdError loadAdError) {
    ResponseInfo responseInfo = loadAdError.getResponseInfo();
    Log.d(TAG, responseInfo.toString());


override fun onAdLoaded() {
    val responseInfo = ad_view.responseInfo
    Log.d(TAG, responseInfo.toString())


override fun onAdFailedToLoad(adError: LoadAdError) {
    val responseInfo = adError.responseInfo
    Log.d(TAG, responseInfo.toString())

Here is a sample output when using Google Mobile Ads SDK version 19.4.0 or higher:

  "Response ID": "MwRtX5mnEYqYmLAPwMKFkAk",
  "Mediation Adapter Class Name": "",
  "Adapter Responses": [{
    "Adapter": "",
    "Latency": 89,
    "Credentials": {},
    "Ad Error": "null"
