java – Google Drive SDK例外

跟踪行文件= request.execute();在上面的代码中(我用星号标记).我在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:

对于未图示的客户端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”).谁知道问题是什么?

解决方法:

编辑:对不起我刚刚意识到我们可以使用debug.keystore在调试模式下签署apk.
因此,最重要的是在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)

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

经过一些试验和错误,我终于能够在我的谷歌硬盘中列出文件
虽然我不确定这是否是最正确的答案,但至少我现在能够列出文件

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

使用JRE7工具使用.keystore生成SHA1密钥

我正在使用我一直在谷歌Play商店使用的.keystore文件
(如果您没有任何密钥库,可以转到项目,单击“导出”,然后它将请求您创建.keystore文件)

使用生成的SHA1密钥,转到您的Google API控制台(最好从新手开始,删除当前项目并开始新项目)

-enable Drive API

-enable Drive SDK

– 访问API ACCESS

– 创建客户端ID

-IMPORTANT在这里,选择Installed application& Android的

-ALSO重要,键入生成的SHA1密钥

-key在您的eclipse项目中使用的CORRECT包名(com.example.xxx)中

– 转到Drive SDK选项卡 – 上载图标

-IMPORTANT,从API Access选项卡键入您的CLIENT 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]

– 插入一个URL

– 获得多个文件支持

同样,请确保代码中的软件包名称与您在Google API控制台中插入的软件包名称相同

最后,在eclipse中,使用刚刚创建的.keystore文件导出项目

将导出的APK文件放入手机中,安装并试用.

检查您的LogCat以显示Google云端硬盘中列出的文件

我成功地用这种方式.

编辑:如果您使用debug.keystore生成SHA1密钥,则可以跳过“导出”部分.只需调试您的应用程序即可. Eclipse将使用debug.keystore自动签署apk.

编辑:下次代码准备就绪时,您需要使用真正的.keystore生成一个新的SHA1密钥,然后输入到Google API控制台.

编辑2:确保您的清单包含这些

<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" />
