使用google play services lib将文件上传到google驱动器（不支持jar文件）

Question

我想使用google play services lib（不使用jar文件）将文件/图像上传到google驱动器。

可以使用Google云端硬盘Android API

Google Drive Android API

I am using quickstart project from Github:-

但是我被困在google play services lib（由于DriveApi.DriveContentsResult）： -

import com.google.android.gms.drive.DriveApi.DriveContentsResult;

错误是： -

import java.io.IOException;
