title: Can't get the selected overlay values individually
body: <p>I am working with a Google map oriented android project now i got a problem in this class i class i used certain overlay to mark nearest places when we touch on particular overlay it will show an alert-box contains name and reference now i am retrieve the reference using the getsnipet() method now i don't want to display the alert-dialog box but when i disable that thing i cannot get the reference can anyone help me to fix this error and here is my code...</p>
