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 fullscreen experience provides developer partners with an opportunity to showcase their best rich content in a dedicated channel outside of their app.
This guide contains instructions for developer partners to integrate their shopping content, using the Engage SDK to populate both this new surface area and existing Google surfaces like Entertainment Space.
Integration detail
Terminology
This integration includes the following five cluster types: Recommendation, Featured, Shopping Cart, Shopping List, Reorder and Shopping Order Tracking.
Recommendation clusters show personalized shopping suggestions from an individual developer partner. These recommendations can be personalized to the user or generalized (for example, trending items). Use these to surface products, events, sales, promos, subscriptions as you see fit.
Your recommendations take the following structure:
Recommendation Cluster: A UI view that contains a group of recommendations from the same developer partner.
ShoppingEntity: An object representing a single item in a cluster.
The Featured cluster showcases a selection of entities from multiple developer partners in one UI grouping. There will be a single Featured cluster, which is surfaced near the top of the UI with a priority placement above all Recommendation clusters. Each developer partner will be allowed to broadcast up to 10 entities in the Featured cluster.
The Shopping Cart cluster shows a sneak peek of shopping carts from many developer partners in one UI grouping, nudging users to complete their outstanding carts. There is a single Shopping Cart 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 up to 3
ShoppingCart
instances in the Shopping Cart cluster.Your Shopping Cart takes the following structure:
Shopping Cart Cluster: A UI view that contains a group of shopping cart previews from many developer partners.
ShoppingCart: An object representing the shopping cart preview for a single developer partner, to be displayed in the Shopping Cart cluster. The
ShoppingCart
must show the total count of items in the cart and may also include images for some items in the user's cart.
The Shopping List cluster shows a sneak peek of the shopping lists from multiple developer partners in one UI grouping, prompting users to return to the corresponding app to update and complete their lists. There is a single Shopping List cluster.
The Reorder cluster shows a sneak peek of the previous orders from multiple developer partners in one UI grouping, prompting users to reorder. There is a single Reorder cluster.
Reorder cluster must show the total count of items in the user's previous order and must also include one of the following:
- Images for X items in the user's previous order.
- Labels for X items in the user's previous order.
The Shopping Order Tracking cluster shows a sneak peek of pending or recently completed shopping orders from many developer partners in one UI grouping, allowing users to track their orders.
There is a single ShoppingOrderTracking cluster that is surfaced near the top of the UI, with a priority placement above all Recommendation clusters. Each developer partner is allowed to broadcast multiple ShoppingOrderTrackingEntity items in the Shopping Order Tracking cluster.
Your ShoppingOrderTrackingCluster takes the following structure:
- ShoppingOrderTracking Cluster: A UI view that contains a group of order tracking previews from many developer partners
- ShoppingOrderTrackingEntity: An object representing a shopping order tracking preview for a single developer partner, to be displayed in the Shopping Order Tracking cluster. The ShoppingOrderTrackingEntity must show the status of the order and the order time. We strongly recommend populating the expected delivery time for ShoppingOrderTrackingEntity, as it's displayed to users when provided.

---|---|---|
Recommendation Cluster(s) | At most 5 | At most 25 ShoppingEntity |
Featured Cluster | At most 1 | At most 10 ShoppingEntity |
Shopping Cart Cluster | At most 1 | At most 3 ShoppingCart
Multiple carts only expected for apps with separate carts per merchant. |

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.
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).

- 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());

Java
client.deleteClusters( new DeleteClustersRequest.Builder() .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

- Statically declare an implementation with the
<receiver>
tag in yourAndroidManifest.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" />
