I have my images on my PC that is stored in htdocs in xampp and the path("C:\xampp\htdocs\project\images\pic.jpg) of that image is in database. How will I parse it to Json and display it on ImageView in Android Studio
It is Cliente / Server architecture , you need some work but it is easy
First you need to create a php file to access your database and retrieve data
Then you make an HTTP request to the XAMPP ( consider using VOLLEY library ) to access the php file
After that you parse the JSON response to get your data
finnaly you display the image using Glide/Picasso library
Hope this help you
Good Luck

I'm really wondering what's the correct and best-practice way for importing data from a json file in an ionic 2 project so I can show it in a template, for example.
Some solutions I can find use interfaces, some don't. Some implement own small services, some don't. Some use http.get().map().subscribe(), some just use subscribe(). I would really like to know how to do this properly and would be glad if somebody could enlighten me.
From my view the best practice is to use a service and use http get request to get json file from your server. We did the same for getting language json file.
If you want securely get json file then you should put your json file at secure folder rather than public folder and create an api to get json file or json object from server.
Hope it will help
i want to handle a requirement in polymer webcomponents where user can upload csv file from ui and csv file can be parsed to json and sent to server ,i searched and found for vaadin upload,looked over the api but i am not sure how to receive the csv file and convert to json and sent to server,can anyone show a jsfiddle of vaadin upload or any other web component to handle this scenario?
First of all, I am wondering why you would not simply do the conversion on the server side.
In this case, you would be able to use the vaadin-upload directly indeed.
Here is a snippet that would upload all files to the example.com server, and only allow CSV files.
<vaadin-upload target="https://example.com/upload" method="POST" accept="text/csv">
</vaadin-upload>
There are plenty of resources on how to convert CSV files to JSON.
Here is a snippet
And here is a node library
If you really wanted to do the conversion client side, then I would suggest to create an element that would embed a vaadin-upload, and convert the Files array to Json before manually calling the uploadFiles method.
I haven't been able to find an example yet but is there a way to use R to send requests to a server? I know of packages that will allow you to convert data to and from JSON files. Essentially I want to request certain data from a server I have set up, that server will then compile a JSON file depending on what I have requested and then R will download the JSON file and then convert it into an R friendly format. I know how to download a JSON file from the server its just the request part that is the issue. Can anyone give an example?
Thanks;
For more info: I'm building a Shiny web app in R. I also have the packages rjson and RJSONIO
You can use a package like httpRequest to send/receive request from server, including JSON payload.
This package has documentation in the form of a PDF.
PS: there may be newer packages available, but this one works for me. Feel free to look for one that'd fit your needs.
this my json file host in remote server.
{"posts":[{"id":"1","message":"message1","details":"5"},{"id":"3","message":"message2","details":"21"}]}
I want to access this file within my blackberry file where id =1. how do i do that? please someone help me
You can start from "Code sample: Parsing a JSON data structure"
at some point in the JSONOutputScreen class maybe you want to add a method to access exactly your stuff
I have a simple DataGrid that gets the Data from a JSON file hosted on a server.
I am using the build Data Connection Wizard and it works great.
Now I want to let the user manipulate the data and send it back to the JSON file.
I tried to add a form to the data grid but it changes only the data on the application and it is not influencing the file on the server.
any help or direction how should i do that will be appreciated.
