在我上面的代码中跟踪到 files = request.execute(); 行(我用星号标记了它).我在我的 Google API 控制台中启用了 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").有谁知道问题出在哪里?
which traces to the line files = request.execute(); in my code above (I have marked it with asterisks). I have enabled both the Drive SDK and the Drive API in my Google APIs Console. Here are a couple of snapshots of my Drive SDK settings:
For the Client ID section that is not pictured, I simply pasted the "Client ID for installed applications" from the API Access section (I also tried the "Client ID for Drive SDK"). Anyone know what the problem is?
推荐答案
已抱歉，我刚刚意识到我们可以在调试模式下使用 debug.keystore 对 apk 进行签名.所以，最重要的是在您的 Google API 控制台中插入正确的 SHA1 密钥.(使用 Stephen Wylie 在他的 Google+ 帖子中提到的 JRE7 工具生成)
EDITED: Sorry I just realized that we can sign the apk in debugging mode using debug.keystore. SO, the most important thing is insert the correct SHA1 key in your Google API console. (generated using the JRE7 tool as mentioned by Stephen Wylie in his Google+ post)
另请参阅 (developer.android.com/tools/publishing/app-signing.html#debugmode) 以获取密钥库密码
Also see (developer.android.com/tools/publishing/app-signing.html#debugmode) for the keystore password
经过反复试验，我终于能够在我的谷歌驱动器中列出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
After some trial and error, I finally able to list files in my google drive Although I am not sure whether this is the most correct answer, but at least I am able to list files now
首先，请参阅 Stephen Wylie 更新的 Google+ 帖子https://plus.google.com/u/0/114042449736049687152/posts/CD3L8zcJg5Z
First, please refer to Stephen Wylie updated Google+ post https://plus.google.com/u/0/114042449736049687152/posts/CD3L8zcJg5Z
使用 JRE7 工具通过 .keystore 生成 SHA1 密钥
generate the SHA1 key with your .keystore using the JRE7 tool
我正在使用在我的 google play 商店中使用的 .keystore 文件(如果你没有keystore，你可以到你的项目，点击export，然后它会要求你创建一个.keystore文件)
I am using the .keystore file that I had been using with my google play store (If you do not have any keystore, you can go to your project, click export, then it will request you to create a .keystore file)
使用生成的 SHA1 密钥，转到您的 Google API 控制台(最好从头开始，删除当前项目并开始一个新项目)
with the generated SHA1 key, go to your Google API console (it is best if you start from fresh, delete the current project and start a new one)
-启用 Drive API
-enable Drive API
-启用 Drive SDK
-enable Drive SDK
-转到 API 访问
-创建客户 ID
-此处重要，选择已安装的应用程序和安卓
-IMPORTANT here, choose Installed application & Android
-同样重要的是，输入您生成的 SHA1 密钥
-ALSO IMPORTANT, key in your generated SHA1 key
-键入您在 Eclipse 项目中使用的正确包名称 (com.example.xxx)
-key in your CORRECT package name (com.example.xxx) that you are using in your eclipse project
-转到Drive SDK选项卡-上传图标
-Go to Drive SDK tab -upload icon
-重要，从 API 访问选项卡中输入您的 CLIENT ID(已安装应用程序的客户端 ID)
-IMPORTANT, key in your CLIENT ID (Client ID for installed applications) from the API Access tab
-插入 Stephen Wylie 帖子中提到的 3 个作用域，[/userinfo.email,/userinfo.profile,/auth/drive]
-Insert 3 scopes mentioned in Stephen Wylie post, [/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称与您插入 Google API 控制台的包名称相同
Again, make sure your package name in your code is same as the package name you inserted into Google API Console
最后，在eclipse中，使用刚才创建的.keystore文件导出你的项目
Finally, in eclipse, export your project using the .keystore file you created just now
将导出的APK文件放入手机，安装试试.
Put the exported APK file into your phone, install and try.
检查您的 LogCat 以显示您的 Google Drive 中列出的文件
Check your LogCat to show the listed files from your Google Drive
我用这种方法成功了.
已如果您使用 debug.keystore 生成了 SHA1 密钥，则可以跳过导出"部分.只需调试您的应用程序就可以了.Eclipse 会自动使用 debug.keystore 对 apk 进行签名.
EDITED: If you generated the SHA1 key with the debug.keystore, you can skip the "Export" part. Just debug your application is OK. Eclipse will automatically sign the apk with debug.keystore.
已下次您的代码准备就绪时，您需要使用您的真实 .keystore 生成一个新的 SHA1 密钥，然后输入到 Google API 控制台.
EDITED: Next time your code is ready, you need to generate a new SHA1 key with your real .keystore, then input into the Google API console.
编辑 2:确保您的清单包含这些
EDITED 2: Make sure your manifest include these
<uses-permission android:name="android.permission.INTERNET" />
<uses-permission android:name="android.permission.GET_ACCOUNTS" />
<uses-permission android:name="android.permission.USE_CREDENTIALS" />
<uses-permission android:name="android.permission.MANAGE_ACCOUNTS" />
