/**
 * Activity that handles passwordless authentication using Email.
 * You'll need to declare it in your app's {@code AndroidManifest.xml}:
 * <pre>{@code
 * <activity
 *  android:name="com.auth0.lock.email.LockEmailActivity"
 *  android:theme="@style/Lock.Theme"
 *  android:label="@string/app_name"
 *  android:screenOrientation="portrait"
 *  android:launchMode="singleTask"/>
 * }</pre>
 *
 * Then just start it like any other Android activity:
 * <pre>{@code
 * Intent lockIntent = new Intent(this, LockEmailActivity.class);
 * startActivity(lockIntent);
 * }
 * </pre>
 *
 * And finally register listeners in {@link android.support.v4.content.LocalBroadcastManager} for these actions:
 * <ul>
 *     <li><b>Lock.Authentication</b>: Sent on a successful authentication with {@link com.auth0.core.UserProfile} and {@link com.auth0.core.Token}.
 *     Or both {@code null} when {@link Lock#loginAfterSignUp} is {@code false} </li>
 *     <li><b>Lock.Cancel</b>: Sent when the user's closes the activity by pressing the back button without authenticating. (Only if {@link Lock#closable} is {@code true}</li>
 * </ul>
 *
 * All these action names are defined in these constants: {@link Lock#AUTHENTICATION_ACTION} and {@link Lock#CANCEL_ACTION}.
