I am drawing route between 18 locations to draw the google map v2.When i start fetching routes it draws route but some times it is not drawing route and it gives JSONException :org.json.JSONException: Index 0 out of range [0..0) at org.json.JSONArray.get(JSONArray.java:263)
and also it gives "error_message" : "You have exceeded your daily request quota for this API." "routes" : [] "status" : "OVER_QUERY_LIMIT"

Thanks in advance.
