Factual Engine / Braze Integration for Android

Factual / Braze SDK for Android

This repository contains the code for an integration between Factual's Engine SDK and Braze's Mobile SDK. Using this library you can configure Factual's Location Engine SDK to send custom events to Braze to better understand users in the physical world and build personalized experiences to drive user engagement and revenue.

Integration with Braze UI

see: engine-braze-integration

Installation

The project artifacts are available from Factual's Bintray Maven repository.

// repository for the Factual artifacts

  compile 'com.factual.engine:braze-engine:3.0.0'
}

Usage

Requirements

• Configured and started Engine client. see here
• Configured Braze client. see here

Tracking Factual Engine Circumstances

Start tracking Factual Engine circumstances by calling BrazeEngineIntegration.pushToBraze() in the onCircumstancesMet() callback of FactualClientReceiver.

public class ExampleFactualClientReceiver extends FactualClientReceiver {

    @Override
    public void onCircumstancesMet(List<CircumstanceResponse> responses) {
      /*
      Max number of "engine_at_" events that should be sent per "engine_" + CIRCUMSTANCE_NAME.
      Default is set to 10.
      */
      int maxAtPlaceEvents = 3;

      /*
      Max number of "engine_near_" events that should be sent per "engine_" + CIRCUMSTANCE_NAME.
      Default is set to 20.
      */
      int maxNearPlaceEvents = 5;
      for (CircumstanceResponse response : responses) {
        /* Send circumstance event to braze */
        BrazeEngineIntegration.pushToBraze(getContext().getApplicationContext(),
              response,
              maxAtPlaceEvents,
              maxNearPlaceEvents);
    }
  }

  ...

}

Be sure to assign the Client Receiver when initializing Engine.

public void initializeEngine() {
    FactualEngine.initialize(this,
        Configuration.ENGINE_API_KEY,
        ExampleFactualClientReceiver.class);
}

Tracking Factual Engine User Journey Spans

Start tracking spans by setting the user journey receiver in the onInitialized() callback of FactualClientReceiver.

@Override
public void onInitialized() {
  try {
    FactualEngine.setUserJourneyReceiver(BrazeEngineUserJourneyReceiver.class);
    FactualEngine.start();
  } catch (FactualException e) {
    Log.e("engine", e.getMessage());
  }
}

Then call BrazeEngineIntegration.trackUserJourneySpans() in the onStarted() method of FactualClientReceiver.

public class ExampleFactualClientReceiver extends FactualClientReceiver {
  @Override
  public void onStarted() {
    Log.i("engine", "Engine has started.");
    /*
    Max number of "engine_span_attached_place" events that should be sent per
    "engine_span_occurred". Default is set to 20.
    */
    int maxAttachedPlaceEventsPerSpan = 10;

    /* Start tracking spans */
    BrazeEngineIntegration.trackUserJourneySpans(getContext().getApplicationContext(),
        maxAttachedPlaceEventsPerSpan);
}

    ...
}
