Android Proguard错误与谷歌驱动器API

我声明在我的项目中使用谷歌驱动API。。如果我使用debug密钥库在电话上运行项目，一切都会很好

当我尝试创建一个签名的APK时，proguard抛出以下错误

我还尝试将以下内容添加到proguard-project.txt中

-dontwarn org.apache.harmony.**
-dontwarn javax.activation.**

如果我添加上述内容，将创建APK，但应用程序在启动时崩溃

谁能帮帮我吗

您引用的类不是Android运行时的一部分。删除引用它们的类，或者如果您只是想抑制警告，请尝试添加

-dontwarn java.awt.*，java.beans.*

添加到proguard配置中

中的其他信息如果我们使用此选项，将创建APK。。但是在我们安装之后。。应用程序崩溃！你在使用javamail吗？如果是，请参见此处：
