another question, If I use addJavascriptInterface(getCurrentPosition, "getCurrentPostion") and make a call in javascript like this : getCurrentposition( successCallback, errorCallback );
and successCallback and ErroCallback are implemented in the JS , how it's works this?! I can use javascript function in that way?
