RichRelevance

Android: Home Page

Overview

The Home screen is the main entry point in your mobile app. You should use Home to instrument the welcome view of your app, such as the view that loads right after the loading screen.

Details

Place your code in your fragment's initialization logic, such as onCreate.

Return Personalization

Use this code when you are requesting and serving personalized product recommendations.

Replace<placement name> with your Placement name.

Placement placement = new Placement(Placement.PlacementType.HOME, "<placement name>");

RichRelevance.buildRecommendationsForPlacements(placement)
  .setCallback(new Callback<PlacementResponseInfo>() {
      @Override
      public void onResult(PlacementResponseInfo result) {          
          int index = 0;
          for(PlacementResponse placement : result.getPlacements()) {
              for(final RecommendedProduct recommendedProduct : placement.getRecommendedProducts()) {
                  // Add your view init logic. The actual implementation will depend on your code.
                  // In this example we will assume items are rendered as TableRows in a TableView.
                  TableRow row = new TableRow(context);
                  row.setId(index);
                  row.addView(detailView);
                  index++;
                  tableView.addLayout(row);
              }
          }
      }
      @Override
      public void onError(Error error) {
          // Use this code block to handle errors
          Log.e(getClass().getSimpleName(), "Error: " + error.getMessage());
      }
  }).execute();

Calling multiple placements

If you want to call multiple placements, simply define your placements and pass them to RichRelevance.buildRecommendationsForPlacements() either as individual arguments or as a Collection<Placement>.

IMPORTANT Placements must always be of the same type per request.

// This example defines placements as individual arguments.
Placement topPlacement = new Placement(Placement.PlacementType.HOME, "recs_top");
Placement middlePlacement = new Placement(Placement.PlacementType.HOME, "recs_middle");

RichRelevance.buildRecommendationsForPlacements(topPlacement, middlePlacement)
// Add callback logic
.execute();
// This example defines placements as an ArrayList. It is equivalent to the example above.
ArrayList<Placement> placements = new ArrayList<>(
    Arrays.asList(
        new Placement(Placement.PlacementType.HOME, "recs_top"),
        new Placement(Placement.PlacementType.HOME, "recs_middle"))
    );

RichRelevance.buildRecommendationsForPlacements(placements)
// Add callback logic
.execute();

Listening Mode

When you do not render personalization in your Home UX, you must still send a Home request using the SDK. This is required so that RichRelevance can gather usage data in order to train your personalization models. In this specific case, you will create a listening placement. Listening placements are a special type of placement that can only log usage data without returning personalization data.

Placement placement = new Placement(Placement.PlacementType.HOME);
RichRelevance.buildRecommendationsForPlacements(placement).execute();
