URLEncodedPostData uepd = new URLE开发者_运维百科ncodedPostData(null, false);
uepd.append("action","LOCN");
uepd.append("a", "@latlon:"+lat+","+log);
uepd.append("title","Stanford University School of Medicin");
uepd.append("description", "XYZ");
String[] args = { "http://gmm/x?"+uepd.toString() };
ApplicationDescriptor ad = CodeModuleManager.getApplicationDescriptors(mh)[0];
ApplicationDescriptor ad2 = new ApplicationDescriptor(ad, args);
ApplicationManager.getApplicationManager().runApplication(ad2, true);

i think you should use kml file.

BrowserSession visit = Browser.getDefaultSession();
visit.displayPage("http://www.geochemie.uni-bremen.de/kml/borabora.kml");

you can test on simulator also.
