How to get google map searched location lat & long in blackberry application?

Question

I have used following code to call Google Maps which is installed in Blackberry device

public void invokeGMaps(GMLocation l) {

    URLEncodedPostData uepd = new URLEncodedPostData(null, false);
    uepd.append("action", "LOCN");
    uepd.append("a",
       "@latlon:" + l.getLatitude() + "," + l.getLongitude());
    uepd.append("title", l.getName());
    uepd.append("description", l.getDescription());
    String[] args = { "http://gmm/x?" + uepd.toString() };
    ApplicationDescriptor ad = CodeModuleManager.getApplicationDescriptors(mh)[0];
    ApplicationDescriptor ad2 = new ApplicationDescriptor(ad, args);
    try {
        ApplicationManager.getApplicationManager().runApplication(ad2, true);
    } catch (ApplicationManagerException e) {
        System.out.println(e.getMessage());
        Dialog.alert("error1 " + e.getMessage());
    } catch (Exception e) {
        Dialog.alert("error2 " + e.getMessage());
    }
}  

this is working fine. I have passed current postion to it.

Suppose user will search any particular location on google maps after going on google maps. so while returning back to application i want searched location latitude & longitude from google maps.

So please give me idea how i will get it in my application from google maps application? Please help me, or any help regarding search location on blackberry how to done it?
