Example 1 with ChooseMfaContinuation

use of com.amazonaws.mobileconnectors.cognitoidentityprovider.continuations.ChooseMfaContinuation in project aws-sdk-android by aws-amplify.

the class CognitoUser method handleChallenge.

/**
 * Find the next step from the challenge. This is an important step in the
 * generic authentication flow. After the responding to a challenge, the
 * results are analyzed here to determine the next step in the
 * authentication process. Like all other methods in this SDK, this is
 * designed to work with Continuation objects. This method returns a
 * {@link Runnable} with the code to be executed, for the next step, to the
 * invoking Continuation. The possible steps are 1) Authentication was
 * successful and we have the tokens, in this case we call
 * {@code onSuccess()} to return the tokens. 2) User password is required,
 * an AuthenticationContinuation is created. 3) MFA validation is required,
 * a MultiFactorAuthenticationContinuation object is created. 4) Other
 * generic challenge, the challenge details are passed to the user.
 *
 * @param challenge REQUIRED: Current challenge details,
 *            {@link RespondToAuthChallengeResult}.
 * @param authenticationDetails OPTIONAL: This is used in the PASSWORD_VERIFIER challenge
 * @param callback REQUIRED: {@link AuthenticationDetails} callback.
 * @param runInBackground REQUIRED: Boolean to indicate the current
 *            threading.
 * @return {@link Runnable} for the next step in user authentication.
