Updating a shared state that is not tied to an event

Here, extensions can skip passing the ACPExtensionEvent (iOS) / Event (Android) parameter to the setSharedEventState method. The Adobe Experience Platform SDKs set the state to be the latest available state for this extension. This process ensures that new events see this state, but events that are in flight can access the older state if necessary.

Java

In the following example, the extension is setting a default state in constructor.

MyExtension(final ExtensionApi extensionApi) {
        super(extensionApi);

        Map<String, Object> customElement = new HashMap<String, Object>();
        customElement.put("customInt", 125);
        customElement.put("customString", "example");
        Map<String, Object> customData = new HashMap<String, Object>();
        customData.put("customElement", customElement);
        Map<String, Object> newEventData = new HashMap<String, Object>();
        newEventData.put("customData", customData);
        ExtensionErrorCallback<ExtensionError> errorCallback = new ExtensionErrorCallback<ExtensionError>() {
            @Override
            public void error(final ExtensionError extensionError) {
                Log.d("MyExtension", String.format("An error occurred while setting the shared state %d %s", extensionError.getErrorCode(), extensionError.getErrorName()));
            }
        };
        getApi().setSharedEventState(newEventData, null, errorCallback);
        ...
    }

Objective-C

In the following example, the extension is setting a default state in the init method.

- (nullable instancetype) init {
    // construct data to be shared in a JSON format
    NSDictionary* newEventData =
    @{@"customData":@{
              @"customElement":@{
                      @"customInt":@125,
                      @"customString":@"example"
                      }
              }};
    NSError* error = nil;
    if (![self.api setSharedEventState:newEventData event:nil error:&error] && error) {
        NSLog(@"Error setting default shared state %@:%ld", [error domain], [error code]);
    }
    ...
}
