Multi ad request for Android

  • Artikel

Overview

This page has instructions and code samples for initiating and configuring a ANMultiAdRequest. ANMultiAdRequest enables the user to use a single universal tag (UTv3) request to initiate multiple auctions, the results of which are returned in a single server response.

ANMultiAdRequest is a concrete class and does not implement any interface. The class adopts the type and behavior of different AdUnits (banner, native, video, etc.) using the same specifications of each AdUnit type. Custom keywords can be assigned to a ANMultiAdRequest and will be inherited by the contained AdUnits. An ANMultiAdRequest has a public facing listener which observes for onMultiAdRequestCompleted() or onMultiAdRequestFailed().

Initialization

Users can select from one of two initialization methods. Both require a memberId and a multiAdRequestListener object as arguments in order for ANMultiAdRequest to be initialized. The memberId and multiAdRequestListener may only be set once per instance. An optional Publisher ID parameter can be set at this time. All AdUnits must contain the same memberId as the one passed in the initialization process AdUnits containing placementIds will use the associated memberId of that placement. Upon successful initialization, a ANMultiAdRequest class instance is returned.

Note

The MultiAdRequest instance will reject AdUnits with memberId values different from their own.

Initialization methods

The following methods are supported in this feature:

Initialize with a list of AdUnits and call the load method

Enables initialization and calls the load method with a single line of code. The instance is initialized with a list of one or more AdUnits. If a failure occurs during the load lifecycle, the class is not initialized and a nil object is returned. When a successful load process occurs, a class instance is returned.

Without publisher ID

anMultiAdRequest = new ANMultiAdRequest(context, memberId, multiAdRequestListener, loadOnInit, ads);

With publisher ID

public ANMultiAdRequest(Context context, int memberId, int publisherId, MultiAdRequestListener multiAdRequestListener, boolean loadOnInit, Ad...ads)

Simple Initialization

This basic initialization returns an instance of the class but takes no action. Configuration can be completed by using class properties and methods. The initialized delegate is set on the AdUnits as they are added.

Without publisher ID

anMultiAdRequest = new ANMultiAdRequest(context, memberId, multiAdRequestListener);

With publisher ID

public ANMultiAdRequest(Context context, int memberId, int publisherId, MultiAdRequestListener multiAdRequestListener)

Arguments

Variable Type Scope Description
memberId int Required A member ID. Any AdUnits contained within the ANMultiAdRequest must have identical memberIds or the ANMultiAdRequest will be rejected. The memberId can also be attained by passing in a placementId.
multiAdRequestListener MultiAdRequestListener Required Used to share information about the response whether it is success or failure.
loadOnInit boolean Optional Boolean value to decide whether to load the ANMultiAdRequest during its initialization.
ads Ad Optional Variable-length argument for taking in a list of Ads.

Configuration

All ANMultiAdRequest configuration properties and methods are the same in type and usage as those used by AdUnits. If properties are set in the ANMultiAdRequest, the AdUnits inherit those properties. They are not permanent, once the ANMultiAdRequest has completed its lifecycle AdUnits revert back to their previous property values.

Parameter Type Description
memberId int A member ID. Any AdUnits contained within the ANMultiAdRequest must have identical memberIds or the ANMultiAdRequest will be rejected by Xandr's Impression Bus. The memberId can also be attained by passing in a placementId.
age String The user's age.
gender AdView.GENDER The user's gender.
externalUid String User generated ID that can be mapped with Xandr's internal IDs and that mapping shared amongst the members of clients with multiple seats.
customKeyword ArrayList<Pair<String, String>> Custom keywords applied to the ANMultiAdRequest. These keywords will be inherited by the attached AdUnits. This list can be supplemented within each AdUnit with additional custom keywords.
AdUnit Ad An AdUnit item to add to the ANMultiAdRequest.

ANMultiAdRequest methods

load()

Loads all contained AdUnits by sending a multi-tag UTv3 request to Xandr's Impression Bus. For each ANMultiAdRequest instance, only one load may be active at a time. Loads are complete when one of the Listner methods is fired. Returns true on success and false on failure.

public boolean load()

addAdUnit(Ad adUnit)

Adds an AdUnit to the ANMultiAdRequest. AdUnits will be rejected if their memberId does not match the memberId assigned to the ANMultiAdRequest or does not match the memberId of the other AdUnits contained within the ANMultiAdRequest. Returns true on success and false on failure.

public boolean addAdUnit(Ad adUnit)

Arguments

Parameter Type Scope Description
AdUnit Ad Required An AdUnit item to add to the ANMultiAdRequest.

removeAdUnit(Ad adUnit)

Removes an AdUnit from the ANMultiAdRequest Returns true on success and false on failure.

public void removeAdUnit(Ad adUnit)

Arguments

Parameter Type Scope Description
AdUnit Ad Required An AdUnit item to remove from the ANMultiAdRequest.

addCustomKeywordWithKey

Adds a custom keyword to the ANMultiAdRequest. Stored as a pair of keys and value, custom keywords are inherited by the AdUnits contained within the ANMultiAdRequest.

public void addCustomKeywords(String key, String value)

Arguments

Parameter Type Scope Description
key String Required The key identifier for the custom keyword.
value String Required The value of the custom keyword.

removeCustomKeywordWithKey

Removes a custom keyword from the MultiAdRequest. The remove keyword will no longer be inherited by the AdUnits contained within the ANMultiAdRequest.

public void removeCustomKeyword(String key)

Arguments

Parameter Type Scope Description
key String Required The key identifier for the custom keyword to be removed.

clearCustomKeywords

Removes all custom keywords from the MultiAdRequest. The cleared keywords will no longer be inherited by the AdUnits contained within the ANMultiAdRequest. 

public void clearCustomKeywords()

stop()

Stops the MultiAdRequest, before the request is completed.

public void stop()

activityOnDestroy()

Destroys the ad-unit after activity is completed to prevent memory leaks.

adUnit.activityOnDestroy()

Note

As best practices:

  • All SDK methods must be called on the main thread.
  • activityOnDestroy() must be called for the attached AdUnits when they are expected to be destroyed.

Example

if (anMultiAdRequest != null) {
            for (WeakReference<Ad> adRef: anMultiAdRequest.getAdUnitList()) {
                Ad ad  = adRef.get();
                if (ad instanceof BannerAdView) {
                    ((BannerAdView) ad).activityOnDestroy();
                } else if (ad instanceof InterstitialAdView){
                    ((InterstitialAdView) ad).activityOnDestroy();
                } else if (ad instanceof VideoAd) {
                    ((VideoAd) ad).activityOnDestroy();
                }
            }
        }

MultiAdRequestListener methods

onMultiAdRequestCompleted()

Returns success of ANMultiAdRequest. Success indicates that all contained AdUnits have loaded and have a clear outcome.

void onMultiAdRequestCompleted()

onMultiAdRequestFailed(ResultCode code)

Returns an error message if the UT Request generated by an ANMultiAdRequest instance fails, for any reason.

void onMultiAdRequestFailed(ResultCode code)
