I am using Third party SDKs (i.e. Apring-Net-Social-Dropbox).
I have a problem when I try to get metadata of path in Hebrew language. In particular, I get the following exception: DropboxApiException - HttpStatusCode.NotFound
Can you explain why I get this error?

I have started a development of a music player. I made some additional kotlin logic to retrieve all audio files meta data on device from the Android as a list of meta data. I'm trying to understand how a native path should look like for just_audio to understand. My current implementation uses a deprecated key - MediaStore.Audio.Media.DATA for contentResolver which returns a path like this /storage/emulated/0/Download/scifri20181123-episode.mp3. Can this path be used by the plugin or I need to find another way to retrieve the path in different format?
The same question is valid for the album art.
Yes, if it's a valid file path, then just_audio will be able to open it. You could pass this into setFilePath:
var filePath = '/storage/emulated/....../foo.mp3';
await player.setFilePath(filePath);
This is a convenience method for:
setAudioSource(AudioSource.uri(Uri.file(filePath)));
where Uri.file(filePath) will create a Uri instance containing something like file:///storage/emulated/..... under the hood.
Note that if your app tries to access any file outside of its own app data/cache directories, it also requires permission to do so, and there are other Flutter packages available to help you with this.
Note also that there is also an existing flutter package using the content resolver API called flutter_audio_query, so if it contains what you need, you might not need to write your own Kotlin code.
I'm in need to read a large number of files from a permanent Dropbox webpage.
The reading part is fine, but I'm having troubles finding a way to list all the files contained within.
To be more precise, I would need something like
files = dir([url_to_Dropbox_directory,'*.file_extension']);
returning the names of all the files.
I've found an example in php, but nothing for MATLAB. Using dir was just an example, I'm looking for any solution to this problem.
How can I get the file list from a permanent Dropbox webpage?
You should use the Dropbox API where you can acces that data by a http request. "file-list-folder" is the specific endpoint that you are looking for.
Here is the documentation for it:
https://www.dropbox.com/developers/documentation/http/documentation#files-list_folder
In addition you could use the SDK for PHP (or others programming languages). I have used the SDK for JS and it's easy and works well.

Can we get file information such as filesize, path of a file(even a large one) without actually uploading it onto the server using scala? PS. I know it can be done using Javascript, but I am searching for another way.
I'm using parse as my backend and would like to use the rest api to store files.
I've already successfully tested creating new data with the curl request here https://www.parse.com/docs/rest#files Now I would like to see what files I have on my parse.
I don't see any view for these in the data browser. Maybe there's a way to get a listing via a get request? How do I list the files stored on my parse backend?
Note that the column type in the parse data browser will be 'file' denoting 'pointer to a file in the parse CDN'....
treat that like a third party CDN where you also, do not have the 'fileList' capability u ask 4.
live with what u get from the parse browser's inclusion of the pointer, click the field in the browser and , depend on your OS/browser/plugins, it will automatic download/play the file depending on the MIME type you supplied in the headers when u uploaded it.
Remember that you can use the parse dashboard to ask it to delete or GC any files no longer pointed to by active class.rows.
IMO - its not hard to live without what you've asked for as long as you know the other features parse includes with these file type pointers/ refs.
i'm beginner with GXT and i'm wondering if there is a way to parse a file and extract some informations without uploading it.
i created a formpanel that contains an uploadFile form but i don't know waht's next, how to get the complete path of the file so i can read/write with java io or how to retrieve the file or is there an alternatif solution, thank you.
Best Regards.
You can do it in some modern browsers using bleeding edge HTML5 apis for which you would need to use GWT JSNI code. There are no api's from GWT team as is.
HTML5 FileReader
FileReader includes four options for reading a file, asynchronously:
FileReader.readAsBinaryString(Blob|File) - The result property will contain the file/blob's data as a binary string.
FileReader.readAsText(Blob|File, opt_encoding) - The result property will contain the file/blob's data as a text string.
FileReader.readAsDataURL(Blob|File) - The result property will contain the file/blob's data encoded as a data URL.
FileReader.readAsArrayBuffer(Blob|File) - The result property will contain the file/blob's data as an ArrayBuffer object.
Example of GWT wrapper over these -

You can read about it more from here - How to retrieve file from GWT FileUpload component?
IMHO you cannot read it .
Due to security reasons javascript(gwt) doesn't have access to the system drives files.
http://en.wikipedia.org/wiki/JavaScript#Security
see Opening a file in local file system in javascript
In order to get the file you need to make a server call.
Instead you can do your validation server side and throw proper messages to user.
P.S : i am not considering modern browser concept.What happens if someone opened in other than so called modern browsers?? Will the programm runs same?? Its always better to do server side validation..
