Answer 1

im new in android but maybe you can do something like this:

JSONObject JsonObject = new JSONObject(json);
JSONArray JsonArray_ = JsonObject .getJSONArray("records");

for (int i = 0; i < numberOfItems; i++) {
JSONObject record= JsonArray_photo.getJSONObject(i);    
parsedObject.number = record.getString("number"); //its the same for all fields        
map.add(parsedObject);
}

I done something like that for my own JSON parser. hope this helps. cheers

I suggest you look at the gson library, which makes it very easy indeed to parse JSON into an object representing the data. So you could create a Record object, with public member variables for number, description, and then use gson to parse the JSON into an object array.

http://code.google.com/p/google-gson/

Add the .jar to your libs folder and then use it like this:

Record[] records = new GsonBuilder().create().fromJson(jsonString,Record[].class)
int number = record[0].number;

Answer 3

The org.json package is included in Android: http://developer.android.com/reference/org/json/package-summary.html

Use is simple:

JSONObject json_object = new JSONObject(String json_string);

Each property can then be accessed as a Java property, eg json_object.property . It will throw a JSONException if the parsing fails for some reason (ie, invalid JSON).
