Extend the DefaultMapViewTouchListener (DefaultMapViewOnTouchListener| arcgis-android ) and then override the onLongPress(MotionEvent event) method to include the details in grabbing the location. Get the physical x, y of the location and use MapView.screenToLocation(point) and take that point and use it in the reverse geocode to change that point to an address.

I hope this helps!

The documentation I sent you is for runtime 100 which is the newer version of the runtime.

Inside your onSingleTap override, do this:

Use the toMapPoint method of the mapview, convert the screen point (x,y) to map coordinates :
MapView | ArcGIS Android 10.2.9 API

Then you can use reverse geocoding to generate an address / place name:
https://developers.arcgis.com/android/10-2/api-reference/reference/com/esri/core/tasks/geocode/Locator.html#reverseGeocode(com.esri.core.geometry.Point, double, com.esri.core.geometry.SpatialReference, com.esri.core.geometry.SpatialReference)
