<div class="moz-cite-prefix">AFAIK web and mobile maps use the <a

(EPSG:3857)</a> projection for rendering their tiles.<br>
<br>
How you put information on top is something different and that
is accomplished with the much easier to handle <a
moz-do-not-send="true"
href="http://en.wikipedia.org/wiki/World_Geodetic_System">WGS84
(EPSG:4326)</a>.<br>
e.g. in Mapsforge (like in other map libs) you put overlays on
the map using with lat, long coordinates.<br>
<br>
Also like Philip mentioned, for OSM geocoding you can use web
services like <a moz-do-not-send="true"
href="http://wiki.openstreetmap.org/wiki/Nominatim">Nominatim</a>
and/or <a moz-do-not-send="true"

There is also photon from komoot (based on nominatim) and pelias
from mapzen<br>
