/**
 * Enable active auto focus, immediately triggering a converging scan.
 *
 * <p>This is typically only used when locking the passive AF has failed.</p>
 *
 * <p>Once active AF scanning starts, {@link AutoFocusStateListener#onAutoFocusScan} will be
 * invoked.</p>
 *
 * <p>If the active scan succeeds, {@link AutoFocusStateListener#onAutoFocusSuccess} with
 * {@code locked == true} will be invoked. If the active scan fails,
 * {@link AutoFocusStateListener#onAutoFocusFail} with {@code scanning == false} will be
 * invoked.</p>
 *
 * <p>After calling this function, submit the new requestBuilder as a separate capture.
 * Do not submit it as a repeating request or the AF trigger will be repeated every time.</p>
 *
 * <p>Create a new repeating request from repeatingBuilder and set that as the updated
 * repeating request.</p>
 *
 * @param repeatingBuilder Builder for a repeating request.
 * @param requestBuilder Builder for a non-repeating request.
 *
 * @param repeatingBuilder Builder for a repeating request.
