 * This example demonstrates an advanced integration that makes use of the different android Views
 * included in the MiSnap SDK to fully customize the UI/UX by recreating an analysis screen.
 * This is an advanced integration example and as such is only suitable for developers whose customization
 * needs are not fulfilled through standard integration types customizations.
 *
 * This example uses the following android Views:
 * * [MiSnapView] to orchestrate the acquisition of frames from the device's camera and analyze them.
 * * [GuideView] to represent a visual guide for the document's alignment.
 * * [HintView] to display hint messages to help the user during the session.
 * * [TorchView] to facilitate the use of the device's camera torch light.
 * * [RecordingIconView] to facilitate the awareness of an ongoing video recording during the session.
 * * [SuccessView] to indicate that the session has concluded successfully.
 *
 * NOTE: Ensure that the provided license has all the necessary features enabled for the target
 *  MiSnap session.
 *
 * @see com.miteksystems.misnap.examples.misnapview for an in-depth example on the usage of the
 * [MiSnapView] APIs.
 * @see com.miteksystems.misnap.workflow.view for more information on the android views used in this
 * example.
 * @see com.miteksystems.misnap.examples.settings for examples on how to easily customize the UI and
 * behavior of the SDK.
