JSONException: Index 5 out of range [0..5)
I'm having some trouble with an App I'm developing right now that uses this JSON Object: http://api.worldweatheronline.com/premium/v1/marine.ashx?q=-34.8799074,174.7565664&key=3477e975c4d9a8a0eaac2b2c818f4&format=json&tide=yes
Some days it works just fine, fetching the data from the JSON Object without a problem and some days I get this kind of error: JSONException: Index 5 out of range [0..5).

Without even changing a single line of code!! The weird thing is that can see the JSON Object in Web Browser.
Has anyone experienced similar situation and could explain why it happens?
Thx!

Answer
I´m pretty sure you have an issue similar to: JSONArray Exception : Index 50 out of range [0..50). Is there any limit on JsonArray
The number of objects inside your .json response will change everyday, you have to define bounds (results.length()):
See this example:
JSONArray results = jsonResponse.getJSONArray("results");
final int numberOfItemsInResp = results.length();
for (int i = 0; i < numberOfItemsInResp; i++){
JSONObject perResult = results.getJSONObject(i);
}
