谷歌驱动器没有创建文件，只是创建文件夹只有Android

Question

我想将SD卡文件复制到Google驱动器中，

我尝试了这段代码，但是它没有创建文件而是创建了一个文件夹。

private void check_folder_exists() {
        Query query =
                new Query.Builder().addFilter(Filters.and(Filters.eq(SearchableField.TITLE, FOLDER_NAME), Filters.eq(SearchableField.TRASHED, false)))
                        .build();
        Drive.DriveApi.query(mGoogleApiClient, query).setResultCallback(new ResultCallback<DriveApi.MetadataBufferResult>() {
            @Override public void onResult(DriveApi.MetadataBufferResult result) {
                if (!result.getStatus().isSuccess()) {
                    Log.e(TAG, "Cannot create folder in the root.");
                } else {
                    boolean isFound = false;
                    for (Metadata m : result.getMetadataBuffer()) {
                        if (m.getTitle().equals(FOLDER_NAME)) {
                            Log.e(TAG, "Folder exists");
                            isFound = true;
                            DriveId driveId = m.getDriveId();
                            create_file_in_folder(driveId);
                            break;
                        }
                    }
                    if (!isFound) {
