我正在尝试使用谷歌库从 Android 应用程序在谷歌云数据存储中读取和写入。
该库是这个：google-api-services-datastore-protobuf-java-v1beta1-rev1-1.0.0
我已经制作了一个使用这个库的 std java 项目，并且一切正常。在Android中，当我尝试编译它时，我收到了这个错误：
[2013-07-01 12:54:33 - AndroidDatastore] Dx 1 error; aborting
[2013-07-01 12:54:33 - AndroidDatastore] Conversion to Dalvik format failed with error 1
所以我也尝试导入源api，但出现数百个错误
过了一会儿，我解决了这个问题并在 android 上启动了应用程序，但我得到了这个运行时错误：

最后的问题是：
我应该如何从 android 访问谷歌云数据存储？
我开始认为这个库与Android不兼容......
谢谢
