无法在 Android 中使用 Google Drive API 上传 Google Drive 中的文件

问题描述

我正在尝试使用 Google Drive API 上传文件，但我的代码卡在了基本上试图创建文件的代码上。

我使用的是 Google Drive V3 API。 https://developers.google.com/drive/api/v3/about-auth

这是我正在尝试的代码。

登录用户凭据

 GoogleAccountCredential credential =
                GoogleAccountCredential.usingOAuth2(
                        getApplicationContext(),Collections.singleton(DriveScopes.DRIVE_FILE));
        credential.setSelectedAccount(account.getAccount());
        googleDriveService =
                new com.google.api.services.drive.Drive.Builder(
                        AndroidHttp.newCompatibleTransport(),new GsonFactory(),credential)
                        .setApplicationName("Notes")
                        .build();

        mDriveServiceHelper = new DriveServiceHelper(googleDriveService);
 AsyncTask<Void,Void,GoogleDriveFileHolder> fileCreate =  createTextFile("TestFileAJ1"," Hi. This is just a text file",null);
            try {
                GoogleDriveFileHolder s = fileCreate.get();
                Log.i(TAG,"File Id:"+s.getId());
            } catch (ExecutionException e) {
                e.printstacktrace();
            } catch (InterruptedException e) {
                e.printstacktrace();
            }

执行卡在代码中提到的那一行。

googleFile = googleDriveService.files().create(Metadata,contentStream).setFields("id")

 public AsyncTask<Void,GoogleDriveFileHolder> createTextFile(final String fileName,final String content,@Nullable final String folderId) {

        AsyncTask<Void,GoogleDriveFileHolder>  task= new AsyncTask<Void,GoogleDriveFileHolder>() {
            @Override
            protected GoogleDriveFileHolder doInBackground(Void... params) {
                Log.i(TAG,"Started Background activity");
                List<String> root;
                if (folderId == null) {
                    root = Collections.singletonList("root");
                } else {
                    root = Collections.singletonList(folderId);
                }
                Log.i(TAG,"Into the executer.");
                File Metadata = new File()
                        .setParents(root)
                        .setMimeType("text/plain")
                        .setName(fileName);
                ByteArrayContent contentStream = ByteArrayContent.fromString("text/plain",content);
                Log.i(TAG,"After content Stream");
                File googleFile = null;
                try {
                    Log.i(TAG,"Before conencting to drive");
                    Drive.Files.List fileList = googleDriveService.files().list();
                    Log.i(TAG,"File list:"+ fileList.toString());
                    //Code is getting stuck at this line
                    googleFile = googleDriveService.files().create(Metadata,contentStream).setFields("id")
                    .execute();
                    Log.i(TAG,"After conencting to drive");
                } catch (IOException e) {
                    e.printstacktrace();
                }
                Log.i(TAG,"Getting Google drive file");
                if (googleFile == null) {
                    try {
                        throw new IOException("Null result when requesting file creation.");
                    } catch (IOException e) {
                        e.printstacktrace();
                    }
                }
                Log.i(TAG,"Before creating file");
                createAFile();
                Log.i(TAG,"After creating file");
                GoogleDriveFileHolder googleDriveFileHolder = new GoogleDriveFileHolder();
                googleDriveFileHolder.setId(googleFile.getId());
                Log.i(TAG,"File created Id:"+googleFile.getId()+" "+googleFile.getName());
                return googleDriveFileHolder;

            }

            @Override
            protected void onProgressUpdate(Void... values) {
                Log.i(TAG,"On process update :"+values.toString());
                super.onProgressUpdate(values);
            }

            @Override
            protected void onPreExecute() {
                Log.i(TAG,"Execution started !!!");
                super.onPreExecute();
            }

        };
        task.execute();
        return task;
    }

请帮忙。

谢谢
