和我的proguard设置。

-ignorewarnings
-keep class * {
    public private *;
}

-keep class kotlin.reflect.** { *; }

-keepclassmembers class ** extends com.fasterxml.jackson.databind.ser.std.** {
   public <init>(...);
}

-keepclassmembers class ** extends com.fasterxml.jackson.databind.deser.std.** {
   public <init>(...);
}


-keep class com.squareup.okhttp.** { *; }
-keep class android.support.v7.widget.** { *; }
-dontwarn com.yalantis.ucrop**
-keep class com.yalantis.ucrop** { *; }
-keep interface com.yalantis.ucrop** { *; }
-keep class org.apache.http.** { *; }

-keepattributes *Annotation*,EnclosingMethod,Signature
-keepnames class com.fasterxml.jackson.** { *; }
-dontwarn com.fasterxml.jackson.databind.**
-keep class org.codehaus.** { *; }
-keepclassmembers public final enum org.codehaus.jackson.annotate.JsonAutoDetect$Visibility {
    public static final org.codehaus.jackson.annotate.JsonAutoDetect$Visibility *; }
-keep public class your.class.** {
    public void set*(***);
    public *** get*();
}

以及gradle文件中的包列表。

当我使用debug设置或删除proguard时，项目运行正常，并设置了以下内容。

到 minifyEnabled,缩水资源,使用Proguard 到假。

即使这个指南也没有帮助。

更新README.md，加入kotlin.reflect的proguard规则。

任何意见和建议都将非常感激。

如果你在Samsung Android 5.x设备上看到这个错误，那么这是一个重复的错误。https:/stackoverflow.coma3035550285472。

除了这个答案之外，还有这个 在Jackson kotlin repo上提交的问题。.
