當使用Azure移動應用程序時，Android prouard崩潰

我在我的新Android項目中使用Azure mobile app。當我在調試模式下運行應用程序時，移動應用程序成功運行，我可以在我的表格中看到我的新記錄。當使用Azure移動應用程序時，Android prouard崩潰

我的問題是開始時，我用proguard創建一個apk文件。我很抱歉地說我是Proguard的新手，那麼即使我閱讀官方Proguard頁面上的文檔，我也無法解決我的Proguard問題。

因此，當我嘗試使用Proguard創建沒有任何Proguard代碼的apk文件時，我得到這些錯誤。

然後我在proguard的添加了這些行。

-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

之後，Android工作室創建了apk然而，應用程序一旦啓動就會被啓動。然後我調查日誌，發現顏色爲白色的新警告。

感謝您的幫助。
