28.15 Configuring the GestureOverlayView
By default, the GestureOverlayView is configured to display yellow lines during gestures. The color used to draw recognized and unrecognized gestures can be defined via the android:gestureColor and android:uncertainGestureColor attributes.

<android.gesture.GestureOverlayView
android:id="@+id/gOverlay"
android:layout_width="0dp"
android:layout_height="0dp"
app:layout_constraintBottom_toBottomOf="parent"
app:layout_constraintEnd_toEndOf="parent"
app:layout_constraintStart_toStartOf="parent"
app:layout_constraintTop_toTopOf="parent"
android:gestureColor...
