我想将Google云端硬盘与我在Google Developers Console中注册我的应用的应用集成.我从https://github.com/googledrive/android-demos获得了一个示例.通过这个我可以在Google驱动器的根文件夹中创建一个文件,文件夹,但问题是我无法在其中创建文件或文件夹现有文件夹.在这种情况下,我得到一个祝酒词"找不到DriveId.您是否有权查看此文件？" 即我无法获得driveID

public class CreateFolderInFolderActivity extends BaseDemoActivity {

@Override
public void onConnected(Bundle connectionHint) {
    super.onConnected(connectionHint);
    Drive.DriveApi.fetchDriveId(getGoogleApiClient(), EXISTING_FOLDER_ID)
            .setResultCallback(idCallback);

    @Override
    public void onResult(DriveIdResult result) {
        if (!result.getStatus().isSuccess()) {
             showMessage(result.getStatus().toString());
            showMessage("Cannot find DriveId. Are you authorized to view this file?");
            return;
        }
        DriveFolder folder = Drive.DriveApi
                .getFolder(getGoogleApiClient(), result.getDriveId());
        MetadataChangeSet changeSet = new MetadataChangeSet.Builder()
                .setTitle("MyNewFolder").build();
        folder.createFolder(getGoogleApiClient(), changeSet)
                .setResultCallback(createFolderCallback);
    }
};

final ResultCallback<DriveFolderResult> createFolderCallback = new
        ResultCallback<DriveFolderResult>() {

    @Override
    public void onResult(DriveFolderResult …
