Android library to dynamically generate views from a given user file

I am trying to find a tool to automatically generate a set of view elements in the fragment.
The idea is to have a user input template file (xml or json), where the user can define the simple fields that he wants to see displayed in the fragment such as TextView, EditText, Buttons or spinner menus.
Then, the app can read that file and load/generate automatically the fields and show them in the fragment.
For example, a user defines the following json file, here define 2 TextFields and one checkbox with 2 options:
{
"sections": [
{
"rows": [
{
"items": [
{
"componentType": "TextField",
"inputType" "text",
"var": "user name"
}
]
}
],
"itemRank": "1",
"title": "User Login Name",
"shortTitle": "login"
},
{
"rows": [
{
"items": [
{
"componentType": "TextField",
"inputType" "float",
"var": "0.0",
"min": "0.0",
"max": "100.0",
"format":"3.3f"
}
]
}
],
"itemRank": "2",
"title": "Weather Temperature",
"shortTitle": "temp"
},
{
"rows": [
{
"items": [
{
"componentType": "multiSelect",
"inputType" "float",
"options": [
{
"text": "Checkbox option 1",
"var": "option1",
"selected": "false"
},
{
"text": "Checkbox option 2",
"var": "option2",
"selected": "false"
}
]
}
]
}
],
"itemRank": "3",
"title": "Weather Temperature",
"shortTitle": "temp"
},
"name": "My json template view elements",
"title": "My report"
}
Having that json file as an input, generate these fields to attach them on the fragment as views and process them accordingly.
Is there a library that can do that?

Integrating PayPal Checkout in an Android app

I am integrating Paypal checkout in an Android App using REST APIs provided by Paypal and my country is India so I am following this guide from PayPal.
How I did as per docs:
Get access-token (/v1/oauth2/token) for further api calls.
Use the Create Order API to create a payment (v2/checkout/orders)and in the response we will get approval url at where you need to redirect user to make the payment.
Now my question is how do I know if payment transaction was successful or not in mobile app because I am using WebView in my app to load approval url.
Order is created like this and I load href inside webview:
{
"id": "1KK44573EX7352015",
"status": "CREATED",
"links": [
{
"href": "https://www.sandbox.paypal.com/checkoutnowtoken=1KK44573EX7352015",
"rel": "approve",
"method": "GET"
}
]
}

I did this way:
As soon as Payment is successfully completed by customer the return_url gets called with query parameters : PayerID & token(orderID). At that time we can update user's payment status in our database (Amount is not deducted yet still because order is yet not approved or captured).
After that we can capture our order (Make sure invoice-id is not duplicate) otherwise status will be not completed.
If order is not approved on the time of capture we get this kind of error:
{
"name": "UNPROCESSABLE_ENTITY",
"details": [
{
"issue": "ORDER_NOT_APPROVED",
"description": "Payer has not yet approved the Order for payment. Please redirect the payer to the 'rel':'approve' url returned as part of the HATEOAS links within the Create Order call or provide a valid payment_source in the request."
}
],
"message": "The requested action could not be performed, semantically incorrect, or failed business validation.",
"debug_id": "47af43e..",
"links": [
{
"href": "https://developer.paypal.com/docs/api/orders/v2/#error-ORDER_NOT_APPROVED",
"rel": "information_link",
"method": "GET"
}
]
}
If there is duplicate invoice-id you will see error at the time of capture:
{
"name": "UNPROCESSABLE_ENTITY",
"details": [
{
"issue": "DUPLICATE_INVOICE_ID",
"description": "Duplicate Invoice ID detected. To avoid a potential duplicate transaction your account setting requires that Invoice Id be unique for each transaction."
}
],

{
"href": "https://developer.paypal.com/docs/api/orders/v2/#error-DUPLICATE_INVOICE_ID",
"rel": "information_link",
"method": "GET"
}
]
}
If there is currency based issue:
{
"name": "UNPROCESSABLE_ENTITY",
"details": [
{
"location": "body",
"issue": "CURRENCY_NOT_SUPPORTED",
"description": "Currency code is not currently supported. Please refer https://developer.paypal.com/docs/integration/direct/rest/currency-codes/ for list of supported currency codes."
}

{
"href": "https://developer.paypal.com/docs/api/orders/v2/#error-CURRENCY_NOT_SUPPORTED",
"rel": "information_link",
"method": "GET"
}
]
}
If your order is successfully captured with status as COMPLETED:

}
After that you can redirect user to thank you page and update mobile app screen based on database values.

How to fetch data from a JSON file in Android Studio

I am trying to make an app showing info from an API. I have searched everywhere but I didn't find an answer that solve my problem!
Here is an example from the JSON file:
{
"status": 200,
"data": {
"date": "2018-10-12T00:00:00.000Z",
"featured": [
{
"id": "5bbdc3abdf819b65ea6b733b",
"name": "Name",
"price": "1",
"priceIcon": "priceicon",
"priceIconLink": "price.png",
"images": {
"icon": "icon.png",
"png": false,
"gallery": false,
"featured": false
},
"rarity": "rarity",
"type": "type",
"readableType": "Type"
}
]
}
}
How can I fetch the name, price, icon, rarity and readableType?
Please don't mark it as duplicate because I haven't found the answer that I am searching for.

}
}
},

Well, it is true that you cannot find any url in the json output. The only thing that you can get from here is the videoId.
You can use this videoId as part of this https://www.youtube.com/watch?v="insert_videoId" to get a video link.
So in your case, this is the link https://www.youtube.com/watch?v=VGDqZjALH_M

Request buildings around and area osm android

I would like to perform a request to OSM Overpass Turbo API or Overpass API from and Android Application so i can get the buildings around and area using JSON.
Something similar to
http://overpass-turbo.eu/ with the query presented below:
[out:json][timeout:25];
// gather results
(
// query part for: “building”
way["building"](37.98350674557998,23.72600823640823,37.98552989685638,23.728837966918945);
relation["building"](37.98350674557998,23.72600823640823,37.98552989685638,23.728837966918945);
);
// print results
out body;
>;
out skel qt;
The thing is that i need the results in geojson like the result below but i cannot find any query that gives me the below result.
{
"type": "FeatureCollection",
"generator": "overpass-turbo",
"copyright": "The data included in this document is from www.openstreetmap.org. The data is made available under ODbL.",

"type": "Feature",

"properties": {

"building": "yes",
"type": "multipolygon"
},
"geometry": {
"type": "Polygon",
"coordinates": [
[
[
23.7319885,
37.9752441

[

37.9748376
],
[
23.7319702,
37.9748318
],
]
]
}
},
I get only results with nodes but not with geometry.
{
"type": "way",
"id": 25107859,
"nodes": [
2373953582,
2373953586,

2373953626,
273319309,
2373953582
],
"tags": {
"building": "yes"
}
},
After some useful comments (thanks scai) i found out that overpass turbo is not queried automatically. Therefore i searched for overpass api and i found out this site with a query for buildings to overpass api exporting to GeoJSON but i does not work (though the xml query in the site works but i need json). Anyone has a query that works so i can follow it?
