copied!<p>what @ohyes means is that you send multiple (too much) requests to google using your API key in too short of a time (for example, over 100 in a minute - just an example). </p> <p>for that you are receiving the <code>OVER_QUERY_LIMIT</code> and the empty JSON array</p> <p>while you should consider changing the time between the requests, you should also verify that the array received in fact has any elements</p> <pre><code>try { // Tranform the string into a json object final JSONObject json = new JSONObject(result); JSONArray routeArray = json.getJSONArray("routes"); if(routeArray.size() > 0) { JSONObject routes = routeArray.getJSONObject(0); JSONObject overviewPolylines = routes.getJSONObject("overview_polyline"); encodedString = overviewPolylines.getString("points"); List<LatLng> list = decodePoly(encodedString); } } catch (JSONException e) { e.printStackTrace(); } </code></pre> <p>That would solve the exception being thrown, but it won't solve the fact that you are getting no result, probably because of the too much requests</p> <p><strong>EDIT:</strong></p> <p>The <code>OVER_QUERY_LIMIT</code> thing happens (probably) because of too fast calls to <code>getJSONFromUrl()</code> function. Please add the code that makes these calls so we could try and be more helpful on that.</p> <p>Probably 500 ms delay is not enough (I'm assuming you're doing this on a background thread and not <code>Sleeping</code> the UI thread as this is a bad habbit). try increasing the delay to something very high, such as a minute (60000 ms) and see if this helps. If it does, lower that number to the lowest one that works.</p> <p>And add the code please.</p>
