I want to display "androidmarker" at where I click on the screen..
My code is above. It is Hello Map View tutorial
http://developer.android.com/resources/tutorials/views/hello-mapview.html
I think I should do it with "onTouchEvent " and try to add it as you
can see at the code. But I don't know how to do it like
GeoPoint point = new GeoPoint(19240000,-99120000);
Can anyone help me please?
Thanks
