Extend the DefaultMapViewTouchListener (DefaultMapViewOnTouchListener| arcgis-android ) and then override the onLongPress(MotionEvent event) method to include the details in grabbing the location. Now depending on what location you are interested in grabbing, you can either call MapView.identifyLayersAsync to identify a layer on the map and send that to an ACTION_SEND intent or if you are interested in getting the physical x, y of the location (in terms of the projection used) you can use MapView.screenToLocation(point) and the point is the point you get from the OnLongPress listener motionevent. Then you can reverse geocode that point to get an address.
