如何从Google云端硬盘下载视频？

Question

我可以下载视频和图像，但是无法播放（不支持文件格式，或者文件损坏了吗？）。
我被困从Google云端硬盘中获取可播放的视频。
任何帮助都是可观的。

-我的按钮onclick旨在使用Google驱动器。

open.setOnClickListener(new View.OnClickListener() {
        @Override
        public void onClick(View v) {
            onClickOpenFile(v);
        }
    });


public void onClickOpenFile(View view) {
    fileOperation = false;

    // create new contents resource
    Drive.DriveApi.newDriveContents(mGoogleApiClient)
            .setResultCallback(driveContentsCallback);
}

打开Goog​​le云端硬盘的文件夹和文件列表

public void OpenFileFromGoogleDrive() {

    IntentSender intentSender = Drive.DriveApi
            .newOpenFileActivityBuilder()
            .setMimeType(new String[]{"image/jpeg", "image/png", "video/mp4"
                    , "application/vnd.openxmlformats-officedocument.wordprocessingml.document"})
            .build(mGoogleApiClient);
    try {
        startIntentSenderForResult(

                intentSender, REQUEST_CODE_OPENER, null, 0, 0, 0);

    } catch (IntentSender.SendIntentException e) {

        Log.e(TAG, "Unable to send intent", e);
    }

}

final ResultCallback<DriveApi.DriveContentsResult> driveContentsCallback =
        new ResultCallback<DriveApi.DriveContentsResult>() {
            @Override
            public void onResult(DriveApi.DriveContentsResult result) {

                if (result.getStatus().isSuccess()) {

                        OpenFileFromGoogleDrive();
                }

            }
        };

@Override
protected void onActivityResult(final int requestCode,
                                final int resultCode, final Intent data) {
    switch (requestCode) {

        case REQUEST_CODE_OPENER:

            if (resultCode == RESULT_OK) {
                video_url = "https://drive.google.com/open?id=" + mFileId.getResourceId();
                Intent i = new Intent(Intent.ACTION_VIEW);
                i.setData(Uri.parse(video_url));
                startActivity(i);
            }
            break;

        default:
            super.onActivityResult(requestCode, resultCode, data);
            break;
    }
}
