当我在寻找如何从 Drive 打开单个电子表格时，我使用了同一个 QuickStart 应用程序，我使用的是 Eclipse Juno，Windows 7，64 位。我看了两个视频，第二个是与 Android Drive App 集成
我使用了这两个步骤，尤其是在我的清单 xml 中。我不得不去看视频两次，以确保我完成了所有步骤。我必须将用户功能添加到我的清单中。
<uses-feature android:name="android.hardware.camera" />
我还发现了其他几件事。我根本无法在模拟器上运行它。在调试模式下在手机上运行它最初也不起作用，它可以访问手机的 SD 卡（显然）。我将APK复制到手机上并安装了它，请确保您的安全设置已放松。当没有通过 ADB 连接时，它可以在我的手机（Jellybean Droid Razr）上运行。
这是我的大部分清单。请注意，您必须将 API 控制台中的“YOURCLIENTID”替换为您的。我只使用了第一组数字，'-'之后什么都没有，即123456789-blah，blah。只是 123456789。

我想我只更改了活动的类名，否则我不必更改任何 java 代码。这是我的活动：
