Help required :Urgent: Hi All, Could anyone help me with my below program. I'm unable to put a transparent label containing the contents from my HelloGoogleMaps.java class (Hola, Mundo!) when i click the markers(the android icon) in the map. I would like to have the ontap event do it for different markers here so that that particular location details is popped up. It needs to be in a canvas display. Upon clicking this new canvas label, it should take me to a seperate activity displaying complete details.
I'm using the sample program given in the Google Android Website http://developer.android.com/resources/tutorials/views/hello-mapview.html and i want to extended it to the next level. Urgent help needed. Thanks in advance..
