/**
 * Base class for implementing an Activity that is used to help implement an
 * AbstractAccountAuthenticator. If the AbstractAccountAuthenticator needs to use an activity
 * to handle the request then it can have the activity extend AccountAuthenticatorActivity.
 * The AbstractAccountAuthenticator passes in the response to the intent using the following:
 * <pre>
 *      intent.putExtra(Constants.ACCOUNT_AUTHENTICATOR_RESPONSE_KEY, response);
 * </pre>
 * The activity then sets the result that is to be handed to the response via
 * {@link #setAccountAuthenticatorResult(android.os.Bundle)}.
 * This result will be sent as the result of the request when the activity finishes. If this
 * is never set or if it is set to null then error {@link AccountManager#ERROR_CODE_CANCELED}
 * will be called on the response.
