Using Mapsforge OverlayApi to add clickable building polygons
<p>2 questions here, would really appreciate any advice.  I'm building an offline android navigation service in which I want the user to be able to click on a building for information/navigation options etc.  Looking into the Overlay API with mapsforge. </p>

<p>First question - the documentation states
"Closed polygons, for example buildings or areas, are also supported. A way node sequence is considered as a closed polygon if the first and the last way node are equal. "
I've tried to add a closed polygon for a building but when I add a way overlay with the identical start and end points it just displays a ring around the area - is there any way to fill this in so the area appears as a block?</p>

<p>Secondly - how would I add some sort of listener to allow the user to click on this polygon?</p>

<p>Hope someone can help!  Thanks! </p>
