Getting LARGE nested Json from NYT API

I'm trying to use the New york times api to show the headline and an image in a listview on android. I'm already getting the data for headline and date and outputting to log cat. The real problem is: whenever I put the extra field to get the mulimedia (images url) the "GC_FOR_ALLOC freed 1902K (64), 22% free 11931K/15156K" is shown
I've seen that the api always sends fixed number of 10 nyt articles, but each of the 10 has a multiple multimedia urls and json with arrays nested and the app freezes. I'll learn to put the data on listview on my own, my real question is, whats the best approach to fix the crash, I only want 1 url image per article.
//THE RETURNED JSON WITH ONLY "MULTIMEDIA" FIELD QUERY.

},

},
// Goes on forever.

What do you use to get the data, what kind of REST client are you using?
For example if you are parsing the response by yourself you can put some logic like
JSONObject obj = new JSONObject(" .... ");
JSONArray arr = obj.getJSONArray("multimedia");
JSONObject firstMultimedia = null;
if (arr.length() > 0){
firstMultimedia = arr.getJSONObject(0);
}

Retrieve List of Layout/View's attributes

I'm working on a small learning-tool project that has several different views displayed in various fragments. What I'd like to do is when the user selects a layout or view (e.g. TextView), a dialog pops up that shows all its available attributes (e.g. android:layout_width, android:layout_height, android:focusable, etc). Rather than going through each layout/view and manually typing the attributes in a file or class, I was hoping there was a way to programmatically get the attributes. Currently, I just have a JSON file I'm reading from, but it's becoming extremely tedious. An issue also arises with different API versions.
Just to get an idea of what I'm currently dealing with, here's my JSON file:
{
"LayoutParams": [
"android:layout_height",
"android:layout_width"
],
"MarginLayoutParams": [
"android:layout_margin",
"android:layout_marginBottom",
"android:layout_marginEnd",
"android:layout_marginHorizontal",
"android:layout_marginLeft",
"android:layout_marginRight",
"android:layout_marginStart",
"android:layout_marginTop",
"android:layout_marginVertical"
],
"RelativeLayout": {
"inherited_properties": [
"MarginLayoutParams",
"LayoutParams"
],
"primary_properties": [{
"android:gravity": ["bottom", "center", "center_horizontal", "center_vertical", "clip_horizontal", "clip_vertical", "end", "fill", "fill_horizontal", "fill_vertical", "left", "right", "start", "top"],
"android:ignoreGravity": [""],
"android:layout_above": [],
"android:layout_alignBaseline": [],
"android:layout_alignBottom ": [],
"android:layout_alignEnd": [],
"android:layout_alignLeft": [],
"android:layout_alignParentBottom": [],
"android:layout_alignParentEnd": [],
"android:layout_alignParentLeft": [],
"android:layout_alignParentRight": [],
"android:layout_alignParentStart": [],
"android:layout_alignParentTop": [],
"android:layout_alignRight": [],
"android:layout_alignStart": [],
"android:layout_alignTop": [],
"android:layout_alignWithParentIfMissing": [],
"android:layout_below": [],
"android:layout_centerHorizontal": [],
"android:layout_centerInParent": [],
"android:layout_centerVertical": [],
"android:layout_toEndOf": [],
"android:layout_toLeftOf": [],
"android:layout_toRightOf": [],
"android:layout_toStartOf": []
}]
}
}

You can extract them from R.stylable.
AFAIK, there's no XML schema or DTD defined, so R.stylable might be your only choice.

Android: Bing image search result customization

I am implementing the Bing search for image searching.
I refered this link, and change my response to JSON.
It works and the result is like:
{
"d": {
"results": [{
"__metadata": {
"uri": "https://api.datamarket.azure.com/Data.ashx/Bing/Search/Image?Query=\u0027Pepsi\u0027&$skip=0&$top=1",
"type": "ImageResult"
},

"SourceUrl": "http://tjthesportsgeek.com/2012/02/14/tale-of-the-tape-coke-vs-pepsi/",
"DisplayUrl": "tjthesportsgeek.com/2012/02/14/tale-of-the-tape-coke-vs-pepsi",
"Width": "1588",
"Height": "2064",

"MediaUrl": "http://ts2.mm.bing.net/th?id=OIP.M7f9b9a39639b9ca8bb6f1cba6e35d041H0&pid=15.1",
"ContentType": "image/jpg",
"Width": "369",
"Height": "480",
"FileSize": "19879"
}
},
// Next array element
]
}
}
but what i need is:
The json result with only MediaUrl and MediaUrl of Thumbnail. (As it is possible in Google Custom Search with the help of tag "field" like fields=items(link,image/thumbnailLink))
The image only with medium size. (I searched for this and applied the filter but of no use.)
Please reply with your valuable suggestions.

You can't filter output fields.
Use the parameter: ImageFilters = Size.Medium

How do you find a user's twitter id from a user's twitter username in Android

In my android app, I want users to be able to enter a twitter username and from there the twitter app launches on the entered username's page. I did some research and found out the link needed to open the twitter app from another app is twitter://user?user_id=id_num I was wondering if there is a way to get the user's twitter id from a twitter username in Android so I can make this happen. Any help would be greatly appreciated, thank you.

You should read through the Twitter API, in particular the section about user lookups
Edit: Links updated to current Twitter API docs though answer remains targeted at API v1.1 as when asked.
That particular request has optional fields to search by id or screen_name and will return a list of matches which you can parse for user ids. So you can search by screen_name and read the response to get an id.
The request you are (were) looking for is:
GET https://api.twitter.com/1/users/lookup.json?screen_name=somename
The provided response in the API examples is (was):

So you can access the id from the results by parsing that JSON response for the "id" field.
Note however that the returned is a JSON array of results and not just a single definitive answer. You will need to work out yourself which is the correct one (order is not guaranteed either so do not assume the first entry is the most likely).
Also worth noting is that even though this is documented as returning 'id' and an integer value, the current preferred usage of ids is to supply 'id_str' and a string representation of the integer. This is due to inconsistencies in how various platforms handle and limit integers. So even if you receive 'id' you should use 'id_str' for future interactions.

Assuming you have a bearer token from the Twitter Developer Platform, you can get the id for a given username with the Twitter API v2 users lookup endpoint.
So for example, if I send an authorized GET request to
https://api.twitter.com/2/users/by?usernames=TwitterDev,TwitterAPI
Response:
{
"data": [
{
"id": "2244994945",
"name": "Twitter Dev",
"username": "TwitterDev"
},
{
"id": "6253282",
"name": "Twitter API",
"username": "TwitterAPI"
}
]
}
Python Code Example:
import requests
bearer_token = '<YOUR_TWITTER_BEARER_TOKEN_HERE>'
headers = {"Authorization": f"Bearer {bearer_token}"}
params = {"usernames": "TwitterDev,TwitterAPI"}
url = "https://api.twitter.com/2/users/by"
# Get list of twitter follows
r = requests.get(url, params=params, headers=headers, timeout=20)
if r.status_code != 200:
raise Exception(
"Request returned an error: {} {}".format(
r.status_code, r.text
)
)
json_response = r.json()
for u in json_response['data']:
username = u['username']
id = u['id']
print(f"The user id for {username} is {id}")
Output:
The user id for TwitterDev is 2244994945
The user id for TwitterAPI is 6253282

retrieve video (categoryID) from youtube using json

i want to upload youtube videos from my app and find those videos after.
to do so i uploaded the videos using v3 youtube api
here is part of the code that use to add title, description Etc.
snippet.setTitle("Test Upload via Java on " + cal.getTime());
snippet.setDescription(
"Video uploaded via YouTube Data API V3 );
// Set your keywords.
List<String> tags = new ArrayList<String>();
tags.add("test");
tags.add("example");
tags.add("java");
tags.add("YouTube Data API V3");
tags.add("erase me");
snippet.setTags(tags);
i want to add catagotyid so i just add :
snippet.setCategoryId("test");
in this moment the upload code stop to work, why ?
to retrieve all the video that upload by my app i need to fill in part line "snippet" (without Quotes) and in id line add my category id like "test" (without Quotes),
and then result catch by json ?
UPDATE :
How should I fill the "try it!" ? to recieve list of catagoryID, And assume that I got the list, how do I know which category to choose?, I think I'm missing something and I do not know what

Try a GET request on this:
https://www.googleapis.com/youtube/v3/videoCategories?part=snippet&regionCode=US&key={YOUR_API_KEY}
Of course you replace the {YOUR_API_KEY} with your key. You should get back something like this:
