GIFs

Braze supports displaying animated GIFs and SVG images by default for HTML in-app messages. For all other in-app messages, a custom image library is required.

Custom image library integration

Braze offers the ability to use a custom image library to display animated GIFs with in-app messages.

Although the example below uses Glide, any image library that supports GIFs is compatible.

Step 1: Creating the image loader delegate

The Image Loader delegate must implement the following methods:

The integration example below is taken from the Glide integration sample app included with the Braze Android SDK.

  @Override
  public void renderUrlIntoCardView(Context context, Card card, String imageUrl, ImageView imageView, BrazeViewBounds viewBounds) {
    renderUrlIntoView(context, imageUrl, imageView, viewBounds);

    } catch (Exception e) {
      Log.e(TAG, "Failed to retrieve bitmap at url: " + imageUrl, e);
    }
    return null;
  }

  @Override
  public void setOffline(boolean isOffline) {
    // If the loader is offline, then we should only be retrieving from the cache
    mRequestOptions = mRequestOptions.onlyRetrieveFromCache(isOffline);
  }
}

class GlideBrazeImageLoader : IBrazeImageLoader {
  companion object {
    private val TAG = GlideBrazeImageLoader::class.qualifiedName
  }

  private var mRequestOptions = RequestOptions()

  override fun renderUrlIntoCardView(context: Context, card: Card, imageUrl: String, imageView: ImageView, viewBounds: BrazeViewBounds) {
    renderUrlIntoView(context, imageUrl, imageView, viewBounds)
  }

  override fun renderUrlIntoInAppMessageView(context: Context, inAppMessage: IInAppMessage, imageUrl: String, imageView: ImageView, viewBounds: BrazeViewBounds) {
    renderUrlIntoView(context, imageUrl, imageView, viewBounds)
  }

  override fun getPushBitmapFromUrl(context: Context, extras: Bundle, imageUrl: String, viewBounds: BrazeViewBounds): Bitmap? {
    return getBitmapFromUrl(context, imageUrl, viewBounds)
  }

  override fun getInAppMessageBitmapFromUrl(context: Context, inAppMessage: IInAppMessage, imageUrl: String, viewBounds: BrazeViewBounds): Bitmap? {
    return getBitmapFromUrl(context, imageUrl, viewBounds)
  }

  private fun renderUrlIntoView(context: Context, imageUrl: String, imageView: ImageView, viewBounds: BrazeViewBounds) {
    Glide.with(context)
        .load(imageUrl)
        .apply(mRequestOptions)
        .into(imageView)
  }

  private fun getBitmapFromUrl(context: Context, imageUrl: String, viewBounds: BrazeViewBounds): Bitmap? {
    try {
      return Glide.with(context)
          .asBitmap()
          .apply(mRequestOptions)
          .load(imageUrl).submit().get()
    } catch (e: Exception) {
      Log.e(TAG, "Failed to retrieve bitmap at url: $imageUrl", e)
    }

    return null
  }

  override fun setOffline(isOffline: Boolean) {
    // If the loader is offline, then we should only be retrieving from the cache
    mRequestOptions = mRequestOptions.onlyRetrieveFromCache(isOffline)
  }
}

Step 2: Setting the image loader delegate

The Braze SDK will use any custom image loader set with setBrazeImageLoader. We recommend setting the custom image loader in a custom application subclass:

public class GlideIntegrationApplication extends Application {

    Braze.getInstance(context).setBrazeImageLoader(new GlideBrazeImageLoader());
  }
}
