Engage SDK Other Verticals: Third-party technical integration instructions

Google is building an on-device surface that organizes users' apps by verticals and enables a new immersive experience for personalized app content consumption and discovery. This full screen experience provides developer partners an opportunity to showcase their best rich content in a dedicated channel outside of their app.

This document contains instructions for developer partners to integrate new content like reservations, events, lodging, places of interest, people and other content. that might not belong to any of these categories using the Engage SDK to populate this new surface area.

Integration detail

Terminology

This integration includes the following three cluster types: Recommendation, Featured, and Continuation.

  • Recommendation clusters show personalized suggestions from an individual developer partner. It is a UI view that contains a group of recommendations from the same developer partner.

    • ArticleEntity: ArticleEntity that represents a text-based recommendation for content that is relevant to more than one category of content. ArticleEntity item allows developers to provide a variety of text and image content with more metadata to articulate the information to the users compared to GenericFeaturedEntity. Ex: Marketing content, News snippet

      Figure 1: UI showing a single ArticleEntity within Recommendations cluster.
    • EventEntity: EventEntity represents an event happening in the future. Event start time is a critical piece of information that needs to be conveyed to the users.

      Figure 2: UI showing a single EventEntity within Recommendations cluster.
    • LodgingEntity: LodgingEntity represents an accommodation, such as a hotel, apartment, vacation home for short term and long term rental.

      Figure 3: UI showing a single LodgingEntity within Recommendations cluster.
    • StoreEntity: StoreEntity represents a store, restaurant, cafe etc. It highlights content where a dining venue or store is the critical piece of information that needs to be conveyed to the users.

      Figure 4: UI showing a single StoreEntity within Recommendations cluster.
    • PointOfInterestEntity: PointOfInterestEntity represents a place of interest like, a gas station, event venue, theme park, museum, tourist attraction, hiking trail etc. It highlights content where location is a critical piece of information that needs to be conveyed to the users. It shouldn't be used for lodging, a store or a dining venue.

      Figure 5: UI showing a single PointOfInterestEntity within Recommendations cluster.
    • PersonEntity: PersonEntity represents a person. The recommendations could be to highlight a person in categories like health and fitness, sports, dating, etc.

      Figure 5: UI showing a single PersonEntity within Recommendations cluster.
  • The Continuation cluster shows content recently engaged by users from multiple developer partners in a single UI grouping. Each developer partner will be allowed to broadcast a maximum of 10 entities in the Continuation cluster.

    Your continuation content can take the following structure:

    • ArticleEntity: ArticleEntity that represents a text-based recommendation for content that is relevant to more than one category of content. This entity can be used to represent unfinished news articles or other content that the user would like to continue consuming from where they left it. Ex: Marketing content, News snippet

      Figure 6. UI showing a single ArticleEntity within a Continuation cluster.
    • RestaurantReservationEntity: RestaurantReservationEntity represents a reservation for a restaurant or cafe and helps users track upcoming or ongoing restaurant reservations.

      Figure 7. UI showing a single RestaurantReservationEntity within a Continuation cluster.
    • EventReservationEntity: EventReservationEntity represents a reservation for an event and helps users track upcoming or ongoing events reservations. Events could include, but not limited to the following:

      • Sports events like reservation for a football match
      • Gaming events like reservation for eSports
      • Entertainment events like reservation for movies in a cinema, concert, theater, book signing
      • Travel or point of interest reservations like guided tours, museum tickets
      • Social / Seminar / Conferences reservations
      • Education / Training sessions reservations
      Figure 8. UI showing a single EventReservationEntity within a Continuation cluster.
    • LodgingReservationEntity: LodgingEntityReservation represents a reservation for a travel lodging and helps users track upcoming or ongoing hotel or vacation rental reservations.

      Figure 9. UI showing a single LodgingReservationEntity within a Continuation cluster.
    • TransportationReservationEntity: TransportationReservationEntity represents a reservation for transportation by any mode and helps users track reservations for upcoming or ongoing flight, ferry, train, bus, ride-hailing, or cruise.

      Figure 10. UI showing a single TransportationReservationEntity within a Continuation cluster.
    • VehicleRentalReservationEntity: VehicleRentalReservationEntity represents a vehicle rental reservation and helps users track upcoming or ongoing vehicle rental reservations.

      Figure 11. UI showing a single VehicleRentalReservationEntity within a Continuation cluster.
  • The Featured cluster is a UI view that showcases the chosen hero GenericFeaturedEntity from many developer partners in one UI grouping. There is a single Featured cluster, which is surfaced near the top of the UI, with a priority placement above all Recommendation clusters. Each developer partner is allowed to broadcast a single entity of a supported type in Featured, with many entities (potentially of different types) from multiple app developers in the Featured cluster.

    • GenericFeaturedEntity: GenericFeaturedEntity differs from Recommendation item in that Featured item should be used for a single top content from developers and should represent the single most important content that will be interesting and relevant to users.

      Figure 12: UI showing a single hero GenericFeaturedEntity card within a Featured cluster

Pre-work

Minimum API level: 19

Add the com.google.android.play:engage library to your app:

dependencies {
    // Make sure you also include that repository in your project's build.gradle file.
    implementation 'com.google.android.engage:engage-core:1.5.2'
}

Summary

The design is based on an implementation of a bound service.

The data a client can publish is subject to the following limits for different cluster types:

Cluster type Cluster limits Minimum entity limits in a cluster Maximum entity limits in a cluster

Additional recommendations

  • Image safe area: Put your important content in the center 80% of the image.
  • Use a transparent background so that the image can be properly displayed in Dark and Light theme settings.

Content Category

The content category allows apps to publish content belonging to multiple categories. This maps the content with some of the predefined categories namely:

  • TYPE_EDUCATION
  • TYPE_SPORTS
  • TYPE_MOVIES_AND_TV_SHOWS
  • TYPE_BOOKS
  • TYPE_AUDIOBOOKS
  • TYPE_MUSIC
  • TYPE_DIGITAL_GAMES
  • TYPE_TRAVEL_AND_LOCAL
  • TYPE_HOME_AND_AUTO
  • TYPE_BUSINESS
  • TYPE_NEWS
  • TYPE_FOOD_AND_DRINK
  • TYPE_SHOPPING
  • TYPE_HEALTH_AND_FITENESS
  • TYPE_MEDICAL
  • TYPE_PARENTING
  • TYPE_DATING

The images are required to be hosted on public CDNs so that Google can access them.

Guidelines to use the content categories

  1. Some entities like ArticleEntity and GenericFeaturedEntity are eligible to use any of the content categories. For other entities like EventEntity, EventReservationEntity, PointOfInterestEntity, only a subset of these categories are eligible. Check the list of categories eligible for an entity type before populating the list.
  2. Use the specific entity type for some content categories over a combination of the Generic entities and the ContentCategory:

    • TYPE_MOVIES_AND_TV_SHOWS - Check out the entities from Watch integration guide before using the generic entities.
    • TYPE_BOOKS - Check out the EbookEntity before using the generic entities.
    • TYPE_AUDIOBOOKS - Check out AudiobookEntity before using the generic entities.
    • TYPE_SHOPPING - Check out ShoppingEntity before using the generic entities.
    • TYPE_FOOD_AND_DRINK - Check out entities from Food Integration guide before using the generic entities.
  3. The ContentCategory field is optional and should be left blank if the content doesn't belong to any of the categories mentioned earlier.

  4. In case multiple content categories are provided, provide them in the order of relevance to the content with the most relevant content category placed first in the list.

Step 2: Provide Cluster data

It is recommended to have the content publish job executed in the background (for example, using WorkManager) and scheduled on a regular basis or on an event basis (for example, every time the user opens the app or when the user just added something to their cart).

AppEngagePublishClient is responsible for publishing clusters.

There are following APIs to publish clusters in the client:

  • isServiceAvailable
  • publishRecommendationClusters
  • publishFeaturedCluster
  • publishContinuationCluster
  • publishUserAccountManagementRequest
  • updatePublishStatus
  • deleteRecommendationsClusters
  • deleteFeaturedCluster
  • deleteContinuationCluster
  • deleteUserManagementCluster
  • deleteClusters

isServiceAvailable

This API is used to check if the service is available for integration and whether the content can be presented on the device.

Kotlin


client.isServiceAvailable.addOnCompleteListener { task ->
    if (task.isSuccessful) {
        // Handle IPC call success
        if(task.result) {
          // Service is available on the device, proceed with content publish
          // calls.
        } else {
          // Service is not available, no further action is needed.
        }
    } else {
      // The IPC call itself fails, proceed with error handling logic here,
      // such as retry.
    }
}

Java


client.isServiceAvailable().addOnCompleteListener(task - > {
    if (task.isSuccessful()) {
        // Handle success
        if(task.getResult()) {
          // Service is available on the device, proceed with content publish
          // calls.
        } else {
          // Service is not available, no further action is needed.
        }
    } else {
      // The IPC call itself fails, proceed with error handling logic here,
      // such as retry.
    }
});

                        .build())
                .build());

When the service receives the request, the following actions take place within one transaction:

    PublishContinuationClusterRequest.Builder()
      .setContinuationCluster(
        ContinuationCluster.Builder()
          .addEntity(entity1)
          .addEntity(entity2)
          .build())
      .build())

Java


client.publishContinuationCluster(
            new PublishContinuationClusterRequest.Builder()
                .setContinuationCluster(
                    new ContinuationCluster.Builder()
                        .addEntity(entity1)
                        .addEntity(entity2)
                        .build())
                .build());

  • Existing UserAccountManagementCluster data from the developer partner is removed.
  • Data from the request is parsed and stored in the updated UserAccountManagementCluster Cluster.

In case of an error, the entire request is rejected and the existing state is maintained.

updatePublishStatus

If for any internal business reason, none of the clusters is published, we strongly recommend updating the publish status using the updatePublishStatus API. This is important because :

  • Providing the status in all scenarios, even when the content is published (STATUS == PUBLISHED), is critical to populate dashboards that use this explicit status to convey the health and other metrics of your integration.
  • If no content is published but the integration status isn't broken (STATUS == NOT_PUBLISHED), Google can avoid triggering alerts in the app health dashboards. It confirms that content is not published due to an expected situation from the provider's standpoint.
  • It helps developers provide insights into when the data is published versus not.
  • Google may use the status codes to nudge the user to do certain actions in the app so they can see the app content or overcome it.

The list of eligible publish status codes are :

// Content is published
AppEngagePublishStatusCode.PUBLISHED,

// Content is not published as user is not signed in
AppEngagePublishStatusCode.NOT_PUBLISHED_REQUIRES_SIGN_IN,

// Content is not published as user is not subscribed
AppEngagePublishStatusCode.NOT_PUBLISHED_REQUIRES_SUBSCRIPTION,

// Content is not published as user location is ineligible
AppEngagePublishStatusCode.NOT_PUBLISHED_INELIGIBLE_LOCATION,

// Content is not published as there is no eligible content
AppEngagePublishStatusCode.NOT_PUBLISHED_NO_ELIGIBLE_CONTENT,

// Content is not published as the feature is disabled by the client
// Available in v1.3.1
AppEngagePublishStatusCode.NOT_PUBLISHED_FEATURE_DISABLED_BY_CLIENT,

// Content is not published as the feature due to a client error
// Available in v1.3.1
AppEngagePublishStatusCode.NOT_PUBLISHED_CLIENT_ERROR,

// Content is not published as the feature due to a service error
// Available in v1.3.1
AppEngagePublishStatusCode.NOT_PUBLISHED_SERVICE_ERROR,

// Content is not published due to some other reason
// Reach out to engage-developers@ before using this enum.
AppEngagePublishStatusCode.NOT_PUBLISHED_OTHER

If the content is not published due to a user not logged in, Google would recommend publishing the Sign In Card. If for any reason providers are not able to publish the Sign In Card then we recommend calling the updatePublishStatus API with the status code NOT_PUBLISHED_REQUIRES_SIGN_IN

Kotlin


client.updatePublishStatus(
   PublishStatusRequest.Builder()
     .setStatusCode(AppEngagePublishStatusCode.NOT_PUBLISHED_REQUIRES_SIGN_IN)
     .build())

Java


client.updatePublishStatus(
    new PublishStatusRequest.Builder()
        .setStatusCode(AppEngagePublishStatusCode.NOT_PUBLISHED_REQUIRES_SIGN_IN)
        .build());

deleteRecommendationClusters

This API is used to delete the content of Recommendation Clusters.

Kotlin


client.deleteRecommendationClusters()

Java


client.deleteRecommendationClusters();

When the service receives the request, it removes the existing data from the Recommendation Clusters. In case of an error, the entire request is rejected and the existing state is maintained.

deleteFeaturedCluster

This API is used to delete the content of Featured Cluster.

Kotlin


client.deleteFeaturedCluster()

Java


client.deleteFeaturedCluster();

When the service receives the request, it removes the existing data from the Featured Cluster. In case of an error, the entire request is rejected and the existing state is maintained.

deleteContinuationCluster

This API is used to delete the content of Continuation Cluster.

Kotlin


client.deleteContinuationCluster()

Java


client.deleteContinuationCluster();

When the service receives the request, it removes the existing data from the Continuation Cluster. In case of an error, the entire request is rejected and the existing state is maintained.

deleteUserManagementCluster

This API is used to delete the content of UserAccountManagement Cluster.

Kotlin


client.deleteUserManagementCluster()

Java


client.deleteUserManagementCluster();

When the service receives the request, it removes the existing data from the UserAccountManagement Cluster. In case of an error, the entire request is rejected and the existing state is maintained.

deleteClusters

This API is used to delete the content of a given cluster type.

Kotlin


client.deleteClusters(
    DeleteClustersRequest.Builder()
      .addClusterType(ClusterType.TYPE_CONTINUATION)
      .addClusterType(ClusterType.TYPE_FEATURED)
      .addClusterType(ClusterType.TYPE_RECOMMENDATION)
      .build())

Java


client.deleteClusters(
            new DeleteClustersRequest.Builder()
                .addClusterType(ClusterType.TYPE_CONTINUATION)
                .addClusterType(ClusterType.TYPE_FEATURED)
                .addClusterType(ClusterType.TYPE_RECOMMENDATION)
                .build());

When the service receives the request, it removes the existing data from all clusters matching the specified cluster types. Clients can choose to pass one or many cluster types. In case of an error, the entire request is rejected and the existing state is maintained.

Error handling

It is highly recommended to listen to the task result from the publish APIs such that a follow-up action can be taken to recover and resubmit an successful task.

Kotlin


client.publishRecommendationClusters(
        PublishRecommendationClustersRequest.Builder()
          .addRecommendationCluster(..)
          .build())
      .addOnCompleteListener { task ->
        if (task.isSuccessful) {
          // do something
        } else {
          val exception = task.exception
          if (exception is AppEngageException) {
            @AppEngageErrorCode val errorCode = exception.errorCode
            if (errorCode == AppEngageErrorCode.SERVICE_NOT_FOUND) {
              // do something
            }
          }
        }
      }

Java


client.publishRecommendationClusters(
              new PublishRecommendationClustersRequest.Builder()
                  .addRecommendationCluster(...)
                  .build())
          .addOnCompleteListener(
              task -> {
                if (task.isSuccessful()) {
                  // do something
                } else {
                  Exception exception = task.getException();
                  if (exception instanceof AppEngageException) {
                    @AppEngageErrorCode
                    int errorCode = ((AppEngageException) exception).getErrorCode();
                    if (errorCode == AppEngageErrorCode.SERVICE_NOT_FOUND) {
                      // do something
                    }
                  }
                }
              });

The error is returned as an AppEngageException with the cause included as an error code.

Error code Note
SERVICE_NOT_FOUND The service is not available on the given device.
SERVICE_NOT_AVAILABLE The service is available on the given device, but it is not available at the time of the call (for example, it is explicitly disabled).
SERVICE_CALL_EXECUTION_FAILURE The task execution failed due to threading issues. In this case, it can be retried.
SERVICE_CALL_PERMISSION_DENIED The caller is not allowed to make the service call.
SERVICE_CALL_INVALID_ARGUMENT The request contains invalid data (for example, more than the allowed number of clusters).
SERVICE_CALL_INTERNAL There is an error on the service side.
SERVICE_CALL_RESOURCE_EXHAUSTED The service call is made too frequently.

Step 3: Handle broadcast intents

In addition to making publish content API calls through a job, it is also required to set up a BroadcastReceiver to receive the request for a content publish.

The goal of broadcast intents is mainly for app reactivation and forcing data sync. Broadcast intents are not designed to be sent very frequently. It is only triggered when the Engage Service determines the content might be stale (for example, a week old). That way, there is more confidence that the user can have a fresh content experience, even if the application has not been executed for a long period of time.

The BroadcastReceiver must be set up in the following two ways:

  • Dynamically register an instance of the BroadcastReceiver class using Context.registerReceiver(). This enables communication from applications that are still live in memory.

Kotlin

class AppEngageBroadcastReceiver : BroadcastReceiver(){
  // Trigger recommendation cluster publish when PUBLISH_RECOMMENDATION broadcast
  // is received
  // Trigger featured cluster publish when PUBLISH_FEATURED broadcast is received
  // Trigger continuation cluster publish when PUBLISH_CONTINUATION broadcast is
  // received
}

fun registerBroadcastReceivers(context: Context){
  var  context = context
  context = context.applicationContext

// Register Recommendation Cluster Publish Intent
  context.registerReceiver(AppEngageBroadcastReceiver(),
                           IntentFilter(Intents.ACTION_PUBLISH_RECOMMENDATION))

// Register Featured Cluster Publish Intent
  context.registerReceiver(AppEngageBroadcastReceiver(),
                           IntentFilter(Intents.ACTION_PUBLISH_FEATURED))

// Register Continuation Cluster Publish Intent
  context.registerReceiver(AppEngageBroadcastReceiver(),
                           IntentFilter(Intents.ACTION_PUBLISH_CONTINUATION))
}

Java

class AppEngageBroadcastReceiver extends BroadcastReceiver {
// Trigger recommendation cluster publish when PUBLISH_RECOMMENDATION broadcast
// is received

// Trigger featured cluster publish when PUBLISH_FEATURED broadcast is received

// Trigger continuation cluster publish when PUBLISH_CONTINUATION broadcast is
// received
}

public static void registerBroadcastReceivers(Context context) {

context = context.getApplicationContext();

// Register Recommendation Cluster Publish Intent
context.registerReceiver(new AppEngageBroadcastReceiver(),
new IntentFilter(com.google.android.engage.service.Intents.ACTION_PUBLISH_RECOMMENDATION));

// Register Featured Cluster Publish Intent
context.registerReceiver(new AppEngageBroadcastReceiver(),
new IntentFilter(com.google.android.engage.service.Intents.ACTION_PUBLISH_FEATURED));

// Register Continuation Cluster Publish Intent
context.registerReceiver(new AppEngageBroadcastReceiver(),
new IntentFilter(com.google.android.engage.service.Intents.ACTION_PUBLISH_CONTINUATION));

}
  • Statically declare an implementation with the <receiver> tag in your AndroidManifest.xml file. This allows the application to receive broadcast intents when it is not running, and also allows the application to publish the content.
<application>
   <receiver
      android:name=".AppEngageBroadcastReceiver"
      android:exported="true"
      android:enabled="true">
      <intent-filter>
         <action android:name="com.google.android.engage.action.PUBLISH_RECOMMENDATION" />
      </intent-filter>
      <intent-filter>
         <action android:name="com.google.android.engage.action.PUBLISH_FEATURED" />
      </intent-filter>
      <intent-filter>
         <action android:name="com.google.android.engage.action.PUBLISH_CONTINUATION" />
      </intent-filter>
   </receiver>
</application>

The following intents is sent by the service:

  • com.google.android.engage.action.PUBLISH_RECOMMENDATION It is recommended to start a publishRecommendationClusters call when receiving this intent.
  • com.google.android.engage.action.PUBLISH_FEATURED It is recommended to start a publishFeaturedCluster call when receiving this intent.
  • com.google.android.engage.action.PUBLISH_CONTINUATION It is recommended to start a publishContinuationCluster call when receiving this intent.
