Question

我在新的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，我可以在表格中看到我的新记录。

当我使用proguard创建apk文件时，我的问题就出现了。我很遗憾地说我是Proguard的新手然后即使我在官方的Proguard页面阅读文档也无法解决我的Proguard问题。

因此，当我尝试使用Proguard创建apk文件而没有任何Proguard代码时，我会收到这些错误。

然后我在我的proguard中添加了这些行。

-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但该应用程序一旦启动就立即生效。然后我调查了日志，我看到了颜色为白色的新警告。
