我正在尝试运行以下代码(主要取自 Stephen Wylie ):

追踪到我上面代码中的 files = request.execute(); 行(我用星号标记了它)。我在我的 Google API 控制台中同时启用了 Drive SDK 和 Drive API。以下是我的 Drive SDK 设置的几个快照: 对于未显示的客户端 ID 部分，我只是从 API 访问部分粘贴了“已安装应用程序的客户端 ID”(我还尝试了“Drive SDK 的客户端 ID”)。有人知道问题出在哪里吗？

Answer 1

已编辑:抱歉，我刚刚意识到我们可以使用 debug.keystore 在 Debug模式下对 apk 进行签名。因此，最重要的是在您的 Google API 控制台中插入正确的 SHA1 key 。 (使用 Stephen Wylie 在他的 Google+ 帖子中提到的 JRE7 工具生成)

另请参阅 (developer.android.com/tools/publishing/app-signing.html#debugmode) 以获取 keystore 密码

经过反复试验，我终于能够列出我的 google 驱动器中的文件虽然我不确定这是否是最正确的答案，但至少我现在可以列出文件了

首先，请引用 Stephen Wylie 更新的 Google+ 帖子 https://plus.google.com/u/0/114042449736049687152/posts/CD3L8zcJg5Z

使用 JRE7 工具通过您的 .keystore 生成 SHA1 key

我正在使用我在我的谷歌游戏商店中使用的 .keystore 文件(如果你没有任何keystore，你可以去你的项目，点击export，然后它会要求你创建一个.keystore文件)

使用生成的 SHA1 key ，转到您的 Google API 控制台(最好是从新开始，删除当前项目并开始一个新项目)

-启用Drive API

-启用Drive SDK

-转到API访问

-创建客户端ID

-此处重要，选择已安装的应用程序和 Android

-另外重要，输入您生成的 SHA1 key

-键入您在 eclipse 项目中使用的正确包名称 (com.example.xxx)

-转到 Drive SDK 选项卡-上传图标

-重要，在 API 访问选项卡中输入您的客户端 ID(已安装应用程序的客户端 ID)

-插入 Stephen Wylie 帖子中提到的 3 个范围，[/userinfo.email,/userinfo.profile,/auth/drive]

-插入网址

-勾选多文件支持

再次确保代码中的包名与插入 Google API 控制台的包名相同

最后，在 eclipse 中，使用您刚才创建的 .keystore 文件导出您的项目

将导出的APK文件放入手机，安装试试。

检查您的 LogCat 以显示您的 Google Drive 中列出的文件

我用这种方式成功了。

已编辑:如果您使用 debug.keystore 生成了 SHA1 key ，则可以跳过“导出”部分。只需调试您的应用程序即可。 Eclipse 将自动使用 debug.keystore 对 apk 进行签名。

已编辑:下次您的代码准备就绪时，您需要使用真实的 .keystore 生成一个新的 SHA1 key ，然后输入到 Google API 控制台。

编辑 2:确保您的 list 包含这些
