在我上面的代碼中跟蹤到 files = request.execute(); 行(我用星號標記了它).我在我的 Google API 控制臺中啟用了 Drive SDK 和 Drive API.以下是我的 Drive SDK 設置的幾個快照:對于未顯示的客戶端 ID 部分，我只是從 API 訪問部分粘貼了已安裝應用程序的客戶端 ID"(我還嘗試了Drive SDK 的客戶端 ID").有誰知道問題出在哪里?
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?
推薦答案
已抱歉，我剛剛意識到我們可以在調試模式下使用 debug.keystore 對 apk 進行簽名.所以，最重要的是在您的 Google API 控制臺中插入正確的 SHA1 密鑰.(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)
另請參閱 (developer.android.com/tools/publishing/app-signing.html#debugmode) 以獲取密鑰庫密碼
Also see (developer.android.com/tools/publishing/app-signing.html#debugmode) for the keystore password
經過反復試驗，我終于能夠在我的谷歌驅動器中列出文件雖然我不確定這是否是最正確的答案，但至少我現在可以列出文件了
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，請參閱 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 工具通過 .keystore 生成 SHA1 密鑰
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(如果你沒有keystore，你可以到你的項目，點擊export，然后它會要求你創建一個.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 密鑰，轉到您的 Google API 控制臺(最好從頭開始，刪除當前項目并開始一個新項目)
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)
-啟用 Drive API
-enable Drive API
-啟用 Drive SDK
-enable Drive SDK
-轉到 API 訪問
-創建客戶 ID
-此處重要，選擇已安裝的應用程序和安卓
-IMPORTANT here, choose Installed application & Android
-同樣重要的是，輸入您生成的 SHA1 密鑰
-ALSO IMPORTANT, key in your generated SHA1 key
-鍵入您在 Eclipse 項目中使用的正確包名稱 (com.example.xxx)
-key in your CORRECT package name (com.example.xxx) that you are using in your eclipse project
-轉到Drive SDK選項卡-上傳圖標
-Go to Drive SDK tab -upload icon
-重要，從 API 訪問選項卡中輸入您的 CLIENT ID(已安裝應用程序的客戶端 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 個作用域，[/userinfo.email,/userinfo.profile,/auth/drive]
-Insert 3 scopes mentioned in Stephen Wylie post, [/userinfo.email, /userinfo.profile, /auth/drive]
-插入網址
-勾選多文件支持
再次確保代碼中的包名稱與您插入 Google API 控制臺的包名稱相同
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，使用剛才創建的.keystore文件導出你的項目
Finally, in eclipse, export your project using the .keystore file you created just now
將導出的APK文件放入手機，安裝試試.
Put the exported APK file into your phone, install and try.
檢查您的 LogCat 以顯示您的 Google Drive 中列出的文件
Check your LogCat to show the listed files from your Google Drive
我用這種方法成功了.
已如果您使用 debug.keystore 生成了 SHA1 密鑰，則可以跳過導出"部分.只需調試您的應用程序就可以了.Eclipse 會自動使用 debug.keystore 對 apk 進行簽名.
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.
已下次您的代碼準備就緒時，您需要使用您的真實 .keystore 生成一個新的 SHA1 密鑰，然后輸入到 Google API 控制臺.
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.
編輯 2:確保您的清單包含這些
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" />
