String message = EntityUtils.toString(getResponseEntity,\"UTF-8\");

         


        

Answer 1

You can get values of json object like this without knowing key

Iterator<String> keys= object.keys();
while (keys.hasNext()) 
{
        String keyValue = (String)keys.next();
        String valueString = object.getString(keyValue);
}

Answer 2

This should work.

JSONObject object = new JSONObject(message);
String objectString = object.getString(object.names().get(0)); 

But it will only work if you sure that NextTransactionUrl node exists. By the way, in this case, this node could have another name, it will still work.
