Question

好的，我的Android应用需要访问用户的Google云端硬盘帐户并修改该帐户的电子表格。我正在使用Google表格API 3.0版来编辑电子表格和Drive API Client Library for Java以便驱动器访问。
现在我知道用户需要授予我的应用访问其信息的权限。现在请纠正我，但这就是我理解这一点的方法。

启动用户选择帐户的活动
在onActivityResult方法上检查结果以查看用户是否授予了权限。

由于我使用两个API（驱动器和电子表格），因此用户必须同时授予这两个API，因此我在下面的代码执行以下操作。

启动用户选择帐户的活动
在onActivityResult方法上选择get accountName，并将其设置为将要使用的帐户。
在我设置要使用的accountName之后的onActivityResult方法中，我在将抛出UserRecoverableAuthIOException的单独线程（Asyn Task）上进行调用，然后使用此异常来提示用户获得Drive API的许可。
在响应用户授予权限的onActivityResult方法中，我在与最后一个类似的单独线程上进行另一次调用，该线程会抛出UserRecoverableAuthException来授权Sheets API。
基本上，用户选择他们想要使用的帐户，然后授予Drive API权限，然后授予Sheets API权限。 我的问题：这是如何授予权限的吗？他们是一种在一个提示中授予Drive和Sheets API权限的方法吗？

当您致电GoogleAuthUtil.getToken时，您可以提供您要授权的所有范围的空格分隔列表。只需包含驱动器和工作表范围。其他一些地方在技术上仍然可以抛出一个auth异常，但如果你先这样做，它就不应该引起提示。

在Android上授权Drive and Sheets API
