JSON data - How to parse?

Suppose I have data in JSON. How can I parse the data so I can get the values of nested objects (e.g. kind, id and title)?
My JSON data is:
{
"kind": "youtube#playlistItemListResponse",
"items": [
{
"id": "UExkc1JWcGJNV19LSH",
"items":[
{
"title": "New Updates",
}
],
}],
}

Well you should remove all the commas since last items should not be followed by one.
So more like:
{
"kind": "youtube#playlistItemListResponse",
"items": [{
"id": "UExkc1JWcGJNV19LSH",
"items": [{
"title": "New Updates"
}]
}]
}
Other than that you can just use JSONObject lib and extract the value you need. For example to get the kind:
JSONObject jsonObj = new JSONObject(strInput);
String kind = jsonObj.getString("kind"); // kind now contains "youtube#playlistItemListResponse"
where strInput is the above json as a string.

Different API hit result with AsyncTask and PostMan

I have a problem when I hit the backend API, I found a difference result on Postman and AsyncTask (httpPost). Why does it happen?
I use the multer-s3-transform nodejs plugin to upload the files into my backend API's, then stored on digitalocean spaces.
Below is a result from AsyncTask:
{
"fieldname":"user_photo",
"originalname":"IMG-20180308_0938_55321.jpg",
"encoding":"7bit",
"mimetype":"application/octet-stream",
"size":84289,
"bucket":"mycdn",
"key":"1e9440387181846f54bece8a5d95a8a9",
"acl":"public-read",
"contentType":"image/jpeg",
"metadata":null,
"location":"https://mycdn.sgp1.digitaloceanspaces.com/1e9440387181846f54bece8a5d95a8a9",
"etag":"\"91ff71e41380602dbc35c94100f88d80\""
}
And this is one from PostMan:
{
"fieldname": "user_photo",
"originalname": "my-photos.png",
"encoding": "7bit",
"mimetype": "image/png",
"transforms": [
{
"id": "or",
"size": 109955,
"bucket": "mycdn",
"key": "users/1520907984802.png",
"acl": "public-read",
"contentType": "image/png",
"metadata": null,
"location": "https://mycdn.sgp1.digitaloceanspaces.com/users/1520907984802.png",
"etag": "\"8e161cab4c516b5eb48c3c1c66987de9\""
}
]
}
My final question, why is the transforms array not showing up in my AsyncTask result?

Getting issue in get id from youtube API

I am trying to get Id from Youtube API in android app but unable to find
https://www.googleapis.com/youtube/v3/channels?part=id&forUsername={username}&key={YOUR_API_KEY}
But getting this response:
{
"kind": "youtube#channelListResponse",
"etag": "\"sNu6csVZt536JdlmpOxN9WQSd8U/ewwRz0VbTYpp2EGbOkvZ5M_1mbo\"",
"pageInfo": {
"totalResults": 0,
"resultsPerPage": 5
},
"items": []
}
I have also tried with this
https://www.googleapis.com/youtube/v3/channels?part=id%2CcontentDetails&mine=true&key={YOUR_API_KEY}
But a response is below:
{
"error": {
"errors": [
{
"domain": "youtube.parameter",
"reason": "authorizationRequired",
"message": "The request uses the \u003ccode\u003emine\u003c/code\u003e parameter but is not properly authorized.",
"locationType": "parameter",
"location": "mine"
}
],
"code": 401,
"message": "The request uses the \u003ccode\u003emine\u003c/code\u003e parameter but is not properly authorized."
}
}

make sure you are logged-in with OAuth when performing these calls and if you're going to parse the JSON response to look for the id, it's found in items.id
Tried this with Channels.list Try-it and I got correct response:
/**
* API response
*/
{
"kind": "youtube#channelListResponse",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejnRI/X6OHzHqUUEu1okILXdfdfBbUxU\"",
"pageInfo": {
"totalResults": 1,
"resultsPerPage": 1
},
"items": [
{
"kind": "youtube#channel",
"etag": "\"VPWTmrH7dFmi4s1RqrK4tLejfdf/Qw3dXynuD_IdfB1LMKjSeiDI\"",
"id": "UCTjdfopNLdfd5yXVv93Ww"
}
]
}

Android Studio and Youtube API Subscriber count?

I'm trying to insert into my app the number of subscribers and views from a channel on YouTube. How do I do that?
I've already setup the YouTube API and gotten my API Key.
I also have the URL that gives me the code below.
How do I turn this:
{
"kind": "youtube#channelListResponse",
"etag": "REMOVED",
"pageInfo": {
"totalResults": 1,
"resultsPerPage": 1
},
"items": [
{
"kind": "youtube#channel",
"etag": "REMOVED",
"id": "REMOVED",
"statistics": {
"viewCount": "13398211",
"commentCount": "28",
"subscriberCount": "182758",
"hiddenSubscriberCount": false,
"videoCount": "84"
}
}
]
}

this is the request you need:
YouTube youTube = new YouTube.Builder(new NetHttpTransport(), new JacksonFactory(), null).setApplicationName("yourAppName").build();
YouTube.Channels.List channelListRequest = youTube.channels().list("statistics");
channelListRequest.setKey(DEVELOPER_KEY);
channelListRequest.setId(channelID);
channelListRequest.setFields("items/statistics(viewCount, subscriberCount)");
ChannelListResponse channelListResponse = channelListRequest.execute();
Channel channel = channelListResponse.getItems().get(0);
at this point you have the Channel object which contains the data you need. You can easly get the data from this object.
BigInteger viewCount = channel .getStatistics().getViewCount();
BigInteger subscriberCount = channel.getStatistics().getSubscriberCount();

same fql(facebook Query Language) shows different result in graph explorer and embedded in javascript code

I am developing hybrid app using cordova, app is intergated with facebook for which i used android SDK.
I need uid of friends of user, for I am using following fql
SELECT name,uid
FROM user
WHERE uid IN (SELECT target_id
FROM connection
WHERE source_id=me() and is_following=1)
ORDER BY name Asc
which is showing different uid in graph API Explorer and in logcat(android ide)
result in graph API Explorer

Probably your app is a Graph API >=v2.0 app, that means it uses app-scoped ids instead of global ids as with v1.0.
The Graph Explorer sometimes inherently uses v1.0 (global ids respectively), even if another version is selected from the pulldown.
