I'm using UnityWebRequest to grab files from the StreamingAssets folder in Android. At the start of my game I want to copy all the files from StreamingAssets to persistentDataPath so I can use normal file operations. To do this, I'd need to iterate through all the files within a folder I have in StreamingAssets. How do I do this using UnityWebRequests? I don't believe any normal file operations work because of how Android packs all the files from StreamingAssets into the apk.

Error in BUILD with UnityWebRequest but not in Editor
Hello i have the following code that's work perfectly in Editor but just crash in .exe buil and WebGL.
In WebGL i have the followings errors.
An error occurred running the Unity content on this page. See your browser JavaScript console for more info. The error was:
uncaught exception: abort("To use dlopen, you need to use Emscripten's linking support, see https://github.com/kripken/emscripten/wiki/Linking")
I searched informations about Emscripten and Linking but i don't understand how to use it and how to solve my problem with it. And i don't think it will solve the problem in the .ex because the error is different : ArgumentNullException : the value can not be null.
Can someone hel me ?

UnityWebRequest works fine until second start of unity
Hi Forum,
I'm experiencing strange behaviour with a UnityWebRequest. When I start the game the first time after Unity launched, it returns the expected string, also when called several times - when it's still the first gamestart. When the game is stopped and restarted, the string is empty.
What's wrong? Or is this a reproducable bug? (Version 2018.4.1f1)
Any help appreciated, I attached the code:

Unity 2018 hits don't show in Google Analytics

How do I have multiple UnityWebRequests in one coroutine?
I have a DLC scenario in my mobile app. It's one download button that will retrieve 2 asset bundles from HTTP links. I've set up an IEnumerator that goes through a UnityWebRequest, gets the asset bundle, stores it, and then disposes itself. The coroutine gets to line 77 where the second UWR should start, and I get this error message:
----------
"InvalidOperationException: Cannot get content from an unfinished UnityWebRequest object"
----------
So, what's going on here? I check to see if the UWR's Download Handler is finished and then dispose of both the handler and the UWR itself. So why am I getting an error message saying that there's an unfinished UWR object? I'm missing something here...
Thanks for the help! Here's my code:

Weird problem with Async Task and UnityWebRequest
Hi everyone
Currently, I am struggling with a weird problem. I am using UnityWebRequest to retrieve data from an API and I am using async Tasks to do this. This is a basic working task which awaits the SendWebRequest() method:
But if I try to implement an async task with an await SendWebRequest() in the class [GltfAsset.cs][2] just like in my example, it doesn't work and says:
> Assets\GLTFast\GltfAsset.cs(31,13):> error CS1061:> 'UnityWebRequestAsyncOperation' does> not contain a definition for> 'GetAwaiter' and no accessible> extension method 'GetAwaiter'> accepting a first argument of type> 'UnityWebRequestAsyncOperation' could> be found (are you missing a using> directive or an assembly reference?)
Could you explain why it is working in my example? I am using the same "using's" and in my example an own class in my own namespace with no extensions..
Thanks in advance! [1]: https://github.com/atteneder/glTFast [2]: https://github.com/atteneder/glTFast/blob/master/Runtime/Scripts/GltfAsset.cs
public static async Task Request(string url)
{
UnityWebRequest request = fetchPrep(url); // function which prepares request for API fetch
await request.SendWebRequest();
if (request.isHttpError)
{
throw new System.Exception("HTTP ERROR " + request.error + url);
}
JsonSerializerSettings setting = jsonSerializerPrep();
string json = request.downloadHandler.text;
Debug.Log(json);
T fetch = JsonConvert.DeserializeObject(json);
return fetch;
}
As I said this code works and there are no errors. Now I wanted to experiment with async tasks to improve this library: [glTFast][1] But if I try to implement an async task with an await SendWebRequest() in the class [GltfAsset.cs][2] just like in my example, it doesn't work and says:

Unity Web Request fails after exporting
Hey everyone,
I'm using UnityWebRequest in order to make a request on my android app. This works perfectly on the editor and I get the correct response code in a blink of an eye.
But after I export the app to Gradle, the web request fails. The cause of failure is "connection timeout".
The weird thing is sometimes it works flawlessly after exporting, but most times it timeouts. I know that this is a network issue. But why is it working 100 percent of times in the editor, and it works like 5 percent of the time after exporting.
I also have internet set to required in the player settings.

Android crashes while receiving multiple files from UnityWebRequest
Hi guys,
i have a problem puzzling me for some days. Basically i have created a grid of sprites and i am downloading many pictures from the web.
The problem is that my app crashes if i download many of them ( 150 or so). I am receining the picture using the UnityWebrequestTexture and then DownloadHandlerTexture.
After that i apply it to the sprite and then i save it to the device storage using File.WriteAllbytes.
I tried using delay ( IEnumerator for each request with a delay of 1 sec but even then it crashes.
I saw somewhere that this is issue has to do with memory usage and i should use streams.
Any ideas?
thanks in advance

How to send a report to server when the game is being closed?
I'm writing a plugin for Unity which needs to `yield return UnityWebRequest.SendWebRequest()` at some points in the game session. Ideally, I also need to send such request if the user closes the game (e.g. by closing the window from the operating system where the game runs).
----------
Actually, for my case, either `onDisable`, `onDestroy` or `onApplicationQuit` would do, however it seems that I can't start a coroutine there because at application termination all gameObjects are getting destroyed and there is simply not enough time to process the web request: not in one frame, not even in a few frames if there were any "grace period" at application closure.
How do games solve such issues?
----------
A solution that comes to mind is to try to send data regularly. However, I'm already doing that. So, the problem is with that last request which doesn't get sent because the application is getting closed abruptly.
----------
Another solution I could think of is to store data which needs to be send (e.g. to PlayerPrefs or to some file) and *on the next app launch* check if there is any data pending to be sent.
However, this won't always work for my case because:
1. The game may never be launched again. The user may just uninstall it. So, data will be lost
2. My server has a max allowed time after which the request will be rejected, so it has to be sent within the game session or shortly after, not 1 month after
----------
Yet another solution: download an executalbe file which would launch in the background, and if the game is closed then in onApplicationQuit use `System.Diagnostics.Process` to run that executable and do the request. However, this is bad in 2 respects:
1. Can't work cross-platform (would need separate executables for Windows, Mac, Linux and other platforms - ideally I want the plugin to run on every platform to which Unity can deploy
2. Each executable would need to handle the network logic in its own way - a work overhead compared to the simple, unified interface Unity offers.
