将数据上载到特定的google驱动器帐户

我正在尝试上传数据(图像或视频)到特定的谷歌驱动器。 (不在用户Google Drive上)

到目前为止我做了什么?

到目前为止,我的应用程序运行良好。用户使用google帐户登录并选择文件。但这个文件会被放到他们的谷歌硬盘上。 我已经使用google drive api搜索了上传到其他google驱动器的数据,但是没有发现任何有用的东西。

我想当用户上传数据(视频)到特定的谷歌驱动器。我有谷歌硬盘的App_键,我想在上面上传数据。

附上我的登录和上传数据的代码。

谢谢您。

GoogleSignInClient googleSignInClient = buildGoogleSignInClient();
startActivityForResult(googleSignInClient.getSignInIntent(), REQUEST_CODE);

private GoogleSignInClient buildGoogleSignInClient() {
    GoogleSignInOptions signInOptions = new GoogleSignInOptions
              .Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)
              .requestScopes(Drive.SCOPE_FILE)
              .build();
          return GoogleSignIn.getClient(this, signInOptions);
    }

使用此上载文件:

    final Task<DriveFolder> rootFolderTask = mDriveResourceClient.getRootFolder();
    final Task<DriveContents> createContentsTask = mDriveResourceClient.createContents();
    Tasks.whenAll(rootFolderTask, createContentsTask)
            .continueWithTask(new Continuation<Void, Task<DriveFile>>() {
                @Override
                public Task<DriveFile> then(@NonNull Task<Void> task) throws Exception {
                    DriveFolder parent = rootFolderTask.getResult();
                    DriveContents contents = createContentsTask.getResult();
                    File file = new File(uri.toString());
                    ByteArrayOutputStream baos = new ByteArrayOutputStream();
                    byte[] buf = new byte[1024];
                    FileInputStream fis = new FileInputStream(file);
                    for (int readNum; (readNum = fis.read(buf)) != -1;) {
                        baos.write(buf, 0, readNum);
                    }
                    OutputStream outputStream = contents.getOutputStream();
                    outputStream.write(baos.toByteArray());

                    MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                            .setTitle("MyVideo.mp4") // Provide you video name here
                            .setMimeType("video/mp4") // Provide you video type here
                            .build();

                    return mDriveResourceClient.createFile(parent, changeSet, contents);
                }
            })
            .addOnSuccessListener(this,
                    new OnSuccessListener<DriveFile>() {
                        @Override
                        public void onSuccess(DriveFile driveFile) {
                            Toast.makeText(MainActivity.this, "Upload Started", Toast.LENGTH_SHORT).show();
                        }
                    })
            .addOnFailureListener(this, new OnFailureListener() {
                @Override
                public void onFailure(@NonNull Exception e) {
                    Log.e(TAG, "Unable to create file", e);
                    Toast.makeText(MainActivity.this, ""+e.getMessage(), Toast.LENGTH_SHORT).show();
                }
            });
