How to Transform a Map to a JSON object in android?

JSON is a convenient format for transporting info across the wire.

public static JSONObject getJSON(Map map) {
Iterator iter = map.entrySet().iterator();
JSONObject holder = new JSONObject();


while (iter.hasNext()) {
Map.Entry pairs = (Map.Entry) iter.next();
String key = (String) pairs.getKey();
Map m = (Map) pairs.getValue();
JSONObject data = new JSONObject();

try {
Iterator iter2 = m.entrySet().iterator();
while (iter2.hasNext()) {
Map.Entry pairs2 = (Map.Entry) iter2.next();
data.put((String) pairs2.getKey(), (String) pairs2.getValue());
}
holder.put(key, data);
} catch (JSONException e) {
Log.e("Transforming", "There was an error packaging JSON",e);
}
}

return holder;
}
