Google Drive SDK for Unity (free, open-sourced)

Hi! Unfortunately, the team drives API is not yet implemented, but I guess I can work on this right now, so it should be available with the new release today or tomorrow. I'll post an update here when it's ready.

 

I've added support for the TeamDrives API. You can download the latest release here: https://github.com/Elringus/UnityGoogleDrive/releases/tag/v0.9-alpha

Unfortunately, I don't have a TeamDrive subscription and wasn't able to test all the API methods (create, delete, list, get, update). I'll be grateful if you could check them out and let me know whether they're working properly.

 

Thank you for the super fast reply! I will try it later today and update you as soon as I can

Seems to be working fine, at least with a really quick test. Thanks again.

I have this same issue. iPhone X 11.3.1

It does not work on wifi or mobile data...

I had the same app and same version of the plugin working on the same device in February. So something must have happened on Apple side since.

All I did was resign the app and build onto the device and suddenly it hangs after browser auth. Auth not going through at all.


I have updated to latest version on github, tried blanx suggestion of modifying the plist, but nothing.

 

I'm still not sure why this is happening (can't even reproduce the issue on my own iPhone), but maybe this could be related to the blocking http listener that is used when completing the auth. I've just added a new release; it will use an async http listener when under .NET 4.x scripting runtime and won't block the app when performing the auth. Can you please check whether that will have any effect on the issue? Don't forget to switch to the .NET 4.x runtime before trying this.

 

Great, that works! Auth request successful and app gets the response.

Is there a way to run a callback when the auth request passes.

Thanks!

 

Hi Elringus,

I had the same problem as Tenebris_Lab and blanx. I could not get the access tokens anymore and only the devices that had already stored access tokens before would work as a result.
Like the Tenebris_Lab I did not change anything before related to your plugin or my xcode SDK so I am also assuming the newest iOS update did change something.

However switching to your newest version from yesterday (and switching to .net 4.6) and using blanx' proposed plist changes fixed this problem. I checked on iPhone7, iPhone 8, iPad Pro 2017 and iPad 2017.

Edit: Also thanks for your great work! Your project really saved me a lot of time.

 

Another question if I may.

I'm not getting any progress value when uploading a file. Its only 0 or 1, any ideas?

 

Nice, glad it worked after all

Auth requests are executed automatically (if needed) when you're performing any kind of Google Drive API requests, so you can just use them and forget about authentication (at least, that's how it's supposed to work). Therefore, there are no public callbacks of methods for the auth-related things. Is there a reason you need a callback for the auth requests?

There was a bug in progress tracking; it's fixed now. Thanks for letting me know!

 

I want to disable a button/gameobject if the client is authenticated. I do this on start and it works great - I asked you about this on GitHub some time ago - by checking the playerpref, but would like to do this when switching back to the app on first time authentication.

Progress fixed, thanks!

 

Might be useful to have an example of File Create for a specific folder. I see you have getting by path.

 

How about wrapping some lightweight request specifically for the auth (like, GoogleDrvieAbout.Get) and just disable the gameobject when it's done?

Well, you can't really create a file in a folder, because a folder in Google Drive is actually a file You just create folder like any other files and then add the ID of that file to other file's 'Parent' property. This is explained in the FAQ on GitHub.

 

After looking into iOS behavior some more a friend told me that localhost is automatically trusted while 127.0.0.1 is not.
I could not find a source quickly to back this claim but testing showed this to be true.

Authentication now works for me on iPhone without modification of plist.info.

So changing the corresponding line in LoopbackAccessTokenProvider.cs seems to solve this.

Code (CSharp):

1. private const string LOOPBACK_URI = @"http://localhost";

 

Thank you for sharing the info! I've initially used localhost, but then found out, that Google recommends against using the alias for local loopback request due to possible issues with some firewalls:



So now I'm not really sure what's better. Guess I'll just add an option to the settings so that users can specify loopback URI they want to use and set 'localhost' as the default one.

 

I've added new release with the option to set specific loopback URI; http://localhost is now used by default.

 

Thank you for implementing this so fast. Hope this saves new users some frustration

 

Hello Elringus.

I am having an issue where the loopback url does not load on iOS (Have not tested android). Switching back to the app does complete auth, and switching back to the browser then completes loading the loopback response.

Any ideas?

 

Can you please share a screenshot and log from the browser console at the moment when redirect to the loopback URI happens? And what version of the plugin are you using?

 

In case you've recently updated to the latest version, make sure that you've added 'localhost' to the authorized redirect uris in the google console app settings (it was 127.0.0.1 previously):

 

Using latest version with async callback. I have added localhost.

Here is the only error in log.

 

Hello Elringus

It seems the localhost callback does not work on some devices.

ERR_CONNECTION_REFUSED issue.

 

Screenshot of issue

 

Well, you can try changing it back to 127.0.0.1 in the GoogleDriveSettings asset (don't forget to whitelist it in the console app).

 

I've created a feedback request to add support for nullable types to JsonUtility: https://feedback.unity3d.com/suggestions/add-support-for-nullable-types-to-jsonutility

Will really appreciate any votes you can spend on this idea

 

hello. just managed to make everything work on android.
the example scene "FilesList"
one hurdle was that i could not get the dependencies because of the missing Java_home in variables.

So now my question :
Is it possible to just access a shared folder on the drive and not require any loging (auth)
from user ?

thanks in advance for any help

 

The auth is mandatory to use drive APIs, including anything related to shared resources.

 

thanks for your answer.
So if i want anyone to be able to log i must share a file with "anyone who has the link" but they must log no matter what.
is this assumption correct?

also could you please explain where the texture or file downloaded goes ?
does it exists in the project somehow or it is just in the memory?
for example when i download a texture (in demo scene) i see it is applied on the renderer but you cannot track back where this texture "exists" in the project at runtime once it was downloaded.
same thing for a text file: i manage to get the text via FilesDownloadRange but when i use FilesGet and use a proper file ID i have no idea where the textfile content goes.

Any clue is welcome !
regards and congrats for this plugin! can't believe it is opensource

 

You'll have to share the resource with specific user account or the user will have to add a publicly-available resource to their drive in order to access it. Though, I'm not 100% sure whether those are the only options, maybe Permissions API (which is not implemented yet) will allow some additional options.

Well, it goes right where you send it When request finishes it's stored in memory, after that you can do anything you want with the data, eg serialize to a local storage or send somewhere else.

 

Hi @Elringus, thank you for this amazing tool, it's working very well.

I'm using your GetFileByPath example but one thing I'm struggling into is getting a file from my Team Drives instead of my regular Drive space.

I tried to enable both request parameters but it doesn't change anything.

Here is my code.

Code (CSharp):

1.     private IEnumerator GetFileByPathRoutine (string filePath)
2.     {
3.         var fileName = filePath.Contains("/") ? filePath.GetAfter("/") : filePath;
4.         var parentNames = filePath.Contains("/") ? filePath.GetBeforeLast("/").Split('/') : null;
5.  
6.         // Resolving folder IDs one by one to find ID of the file's parent folder.
7.         var parendId = "root"; // 'root' is alias ID for the root folder in Google Drive.
8.         if (parentNames != null)
9.         {
10.             for (int i = 0; i < parentNames.Length; i++)
11.             {
12.                 request = new GoogleDriveFiles.ListRequest();
13.                 request.Fields = new List<string> { "files(id)" };
14.                 request.Corpora = "teamDrive";
15.                 request.IncludeTeamDriveItems = true;
16.                 request.SupportsTeamDrives = true;
17.                 request.TeamDriveId = "0APEGo8Jgq2HfUk9PVA";
18.  
19.                 request.Q = string.Format("'{0}' in parents and name = '{1}' and mimeType = 'application/vnd.google-apps.folder' and trashed = false",
20.                     parendId, parentNames[i]);
21.  
22.                 yield return request.Send();
23.  
24.                 if (request.IsError || request.ResponseData.Files == null || request.ResponseData.Files.Count == 0)
25.                 {
26.                     result = string.Format("Failed to retrieve '{0}' part of '{1}' file path.", parentNames[i], filePath);
27.                     yield break;
28.                 }
29.  
30.                 if (request.ResponseData.Files.Count > 1)
31.                     Debug.LogWarning(string.Format("Multiple '{0}' folders been found.", parentNames[i]));
32.  
33.                 parendId = request.ResponseData.Files[0].Id;
34.             }
35.         }
36.  

Do you know what I'm missing?

Thanks again!

 

Well, I haven't actually tested Team Drives myself, so can't tell for sure what is wrong. Can you try using the async helpers? Maybe they will work better.

 

Also, try using the list request in isolation to list any team drive files to check whether it's working by itself.

 

Is it possible to configure this using a google drive API key? If so, is there an example somewhere? I'm wanting to have a WebGL app store files (not user files) on google drive.

 

Actually, the only way to configure the plugin is to use google drive api app credentials. You can find the setup guide on the GitHub page. Be aware, though, that it's mandatory to complete a per-user authentication to use the Drive.

 

Thanks for the quick reply. It seems that all the cloud storage options request per-user authentication. I'm looking for a solution that hearkens back to the good ol' REST API days where you have an API key. I may just have to go that route unless someone knows of a better solution.

 

Well, GDrive is for private user/team data, no surprise it requires per-user auth. For your case I'd suggest something like this: https://firebase.google.com/products/firestore/

 

Thanks, Elringus! I'm building a WebGL app and while they have a Unity SDK for Firebase (which doesn't support web apps), there is no Unity SDK for Firestore (which supports web apps). :-(

 

Hi Elringus, I'm searching a plugin to do cloud save game for android, is this project can do this? I see it provided very free way to manage file on google drive, very powerful.
If i use it to do my game's cloud save, any problem? How to do the file conflict if user have multiple saved games on different device? Thank you.

 

Hi, I guess it should work just ok, but you'll never know until you try

 

OK i'll give it a try. Thanks.

 

Hey,I want to use this package to upload gamesave data. How would I use Googles Appdata for this so players can't tamper with the gamesave?

 

Hi, Please consult the official API docs on how to use the appdata feature: https://developers.google.com/drive/api/v3/appdata

 

Hey, I'm looking forward to using this for our project, hope to get it off the ground and working with spreadsheets.
but i'm having some trouble, since important and completing the setup, I am left with some compile errors that aren't making sense.
I am using Unity 2018.2.8f1 (64bit)
Iam wondering if I have a config or network setting that is conflicting.

Hi, I can't see any references to the UnityGoogleDrive plugin in the logs you've shared. The issue is probably with something else.

 

Never mind, I think when I renamed something it screwed up my entire unity project.
I'm glad I have been able to find the forums to discuss the SDK however.
I'm not the best C# coder by far, but I was wondering if I could get some advice on how I would want to search a directory and find a google spreadsheet and read its table data?

 

Here is a high-level info on the matter: https://github.com/Elringus/UnityGoogleDrive#how-to-access-a-file-using-its-path And you can find more info in the drive API docs.

 

Thanks for the link, I've got it working but I have one question, I'd like for it to use my apps drive, not the users Google Drive but it doesn't like the Service Account's Json generated, nor does it seem to support this in the Google Drive Settings.
Suggestions?

 

Well, if you'd like it to use your apps drive, then just use your apps drive credentials when logging in.

 

I am confused, would I make a call with the helper or tweak some settings in Google Drive Settings?
I changed the Client_id and other settings to match the App auth token but when I loaded the project onto a second machine, it still asked for authorization on a second machine.

Edit: Reading through the forum, I saw mention of Firebase and other cloud-based storage implementation, so I might have to drop it as I can't give out the app login credentials to anyone, team or not.

 

I guess you're trying to use Google Drive as a replacement for a database, but it's not intended to be used like that. Auth is mandatory when user is accessing a drive account for the first time.
