I have a small problem parsing json response because it constantly keeps on getting updated whenever i send a request.All the examples I have seen makes us provide the tag name. My question is that I am trying to parse data from a request sent through an API and I want to list out all the tags of all JSON Arrays existing within a JSON Object before I start parsing. Is it possible in android. http://api.yamgo.tv/channel?apiKey=187abeefc53f900600dc0fc5b8f913a0&token=892e069fa48eead5e7f84cddafe7f0ba This is the request I am sending and it gives me a json response. which has channels as a json object and within it many json arrays with tags like bollywood, entertainment, music,etc. Use an online parser for the response to check it out. I want this list of array names. How can I do it. Could anyone please help. Thanks.

其实，我理解了它与我的一个朋友一个小的帮助。需要使用iterator对象。 这里是code中的片段

I actually figured it out with a small help from one of my friend. Needed the use of Iterator object. Here is the snippet of code

JSONObject channels = jobj.getJSONObject(TAG_CHANNELS);
    Iterator<?> keys=channels.keys();
    while( keys.hasNext() )
    {
        String key = (String)keys.next();
        Log.e("Key", key);
        if( channels.get(key) instanceof JSONArray ){
            jsontags.add(key);
        }
    }
