Example 16 with HttpStatusException

use of org.edx.mobile.http.HttpStatusException in project edx-app-android by openedx.

the class ErrorHandlingCallback method onResponse.

/**
 * The original callback method invoked by Retrofit upon receiving an HTTP response. This method
 * definition provides extra information that's not needed by most individual callback
 * implementations, and is also invoked when HTTP error status codes are encountered (forcing
 * the implementation to manually check for success in each case). Therefore this implementation
 * delegates to {@link #onResponse(Object)} in the case where it receives a successful HTTP
 * status code, and to {@link #onFailure(Call, Throwable)} otherwise, passing an instance of
 * {@link HttpStatusException} with the relevant error status code. This method is
 * declared as final, as subclasses are meant to be implementing the abstract
 * {@link #onResponse(Object)} method instead of this one.
 * <p>
 * This implementation takes care of invoking the callback for request process completion.
 *
 * @param call The Call object that was used to enqueue the request.
 * @param response The HTTP response data.
