Google Drive for Unity3D

Introduction

Google Drive for Unity3D plugin.

You can upload files, explore, download on the Google Drive storage.

This plugin supports PC(Windows and Mac), Android and iOS.

• Google Drive supports 'App Data' that is only accessible by your application. See https://developers.google.com/drive/appdata

Installation

Step 1: Enable the Google Drive API.

• PC and iOS: https://developers.google.com/drive/v3/web/quickstart/ios (Step 1)

• Android: https://developers.google.com/drive/v3/web/quickstart/android (Step 1, 2)

Step 2: Type Your Client ID and Secret to DriveTest.cs.

In the line 40:

drive.ClientID = "YOUR CLIENT ID";
drive.ClientSecret = "YOUR CLIENT SECRET";

• PC and iOS can use same Client ID and secret.

• Android doesn't need Client ID and secret.

Step 3: Run the Sample Scene 'DriveTest'.

All done!

• Android APK: unitydrivetest.apk

Sample Code

var drive = new GoogleDrive();
drive.ClientID = "YOUR CLIENT ID";
drive.ClientSecret = "YOUR CLIENT SECRET";

// Request authorization.
var authorization = drive.Authorize();
yield return StartCoroutine(authorization);

if (authorization.Current is Exception)
{
   Debug.LogWarning(authorization.Current as Exception);
   yield break;
}

// Authorization succeeded.
Debug.Log("User Account: " + drive.UserAccount);

// Upload a text file.
var bytes = Encoding.UTF8.GetBytes("world!");
yield return StartCoroutine(drive.UploadFile("hello.txt", "text/plain", bytes));

// Get all files.
var listFiles = drive.ListAllFiles();
yield return StartCoroutine(listFiles);

var files = GoogleDrive.GetResult<List<GoogleDrive.File>>(listFiles);
if (files != null)
{
   foreach (var file in files)
   {
       // Download a text file and print.
       if (file.Title.EndsWith(".txt"))
       {
           var download = drive.DownloadFile(file);
           yield return StartCoroutine(download);
           
           var data = GoogleDrive.GetResult<byte[]>(download);
           Debug.Log(System.Text.Encoding.UTF8.GetString(data));
       }
   }
}

Work with 'App Data':

// Upload score in 'AppData'.
int score = 10000;
var bytes = Encoding.UTF8.GetBytes(score.ToString());

// User cannot see 'score.txt'. Only your app can see this file.
StartCoroutine(drive.UploadFile("score.txt", "text/plain", drive.AppData, bytes));
