OPENSEAMAP FOR ORUXMAPS

I understood you could edit the onlinemapsources.xml file on my Galaxy S II smartphone for OpenSeaMap to be included in
the online map directory. I added the following but I can not find the maps?

<onlinemapsource uid="19">
<name>Open Sea</name>
<url><![CDATA[http://a.tile.openstreetmap.org/{$z}/{$x}/{$y}.png]]></url>
<minzoom>1</minzoom>
<maxzoom>19</maxzoom>
<projection>MERCATORESFERICA</projection>
<servers></servers>
<httpparam name=""></httpparam>
<cacheable>1</cacheable>
<downloadable>1</downloadable>
<maxtilesday>0</maxtilesday>
<maxthreads>0</maxthreads>
<xop></xop>
<yop>0</yop>
<zop></zop>
<qop></qop>
</onlinemapsource>

Ideas anybody???
