当 Eclipse 在构建快速入门：在 Android示例应用程序上运行 Drive 应用程序时包含 proguard 时，应用程序将失去上传文件的能力。
鉴于应用程序的发布版本在没有 proguard 的情况下可以正常工作，Google API 客户端 ID 似乎配置正确。但是，当在启用了 proguard 的 Eclipse 中构建时，相同的发布版本应用程序的文件上传不起作用。这是我有问题的proguard配置文件：
# To enable ProGuard in your project, edit project.properties
# to define the proguard.config property as described in that file.
#
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in ${sdk.dir}/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the ProGuard
# include property in project.properties.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html

我是一个proguard新手。关于正确的 proguard 配置应该是什么的任何提示？
更新：
我将此问题提交给 Android 问题跟踪器（问题 54765）。
更新 2： 现在 Google Drive Android API 已在 Google Play 服务中实现，我的应用程序大小已减小，并且 proguard 的设置已完整记录。都是好事。
