当使用Azure移动应用程序时，Android prouard崩溃

我在我的新Android项目中使用Azure mobile app。当我在调试模式下运行应用程序时，移动应用程序成功运行，我可以在我的表格中看到我的新记录。当使用Azure移动应用程序时，Android prouard崩溃

我的问题是开始时，我用proguard创建一个apk文件。我很抱歉地说我是Proguard的新手，那么即使我阅读官方Proguard页面上的文档，我也无法解决我的Proguard问题。

因此，当我尝试使用Proguard创建没有任何Proguard代码的apk文件时，我得到这些错误。

然后我在proguard的添加了这些行。

-keep class okio.** { *; } 
-dontwarn okio.** 
-keep class com.fasterxml.** { *; } 
-dontwarn com.fasterxml.** 

-dontwarn javax.annotation.** 
-dontwarn javax.inject.** 
-dontwarn sun.misc.Unsafe 

-keep class com.microsoft.windowsazure.mobileservices.** { *; } 
-dontwarn android.os.** 
-dontwarn com.microsoft.windowsazure.mobileservices.RequestAsyncTask

之后，Android工作室创建了apk然而，应用程序一旦启动就会被启动。然后我调查日志，发现颜色为白色的新警告。
