以下代码行通常适用于我: val users: Array<Catalog> = com.google.gson.Gson().fromJson(data, Array<MyUserClass>::class.java)
但是当我启用proguard时,我得到了一个错误:
java.lang.classcastexception:com.google.gson.internal.linkedtreemap不能强制转换为com.example.app.models.mymodel MyUserClass
具体如下: data class MyUserClass(var posts: List<UserPosts>)
所以gson做得很好 users
是 MyUserClass
-但不是 MyUserClass
成为一个 UserPosts
,它最终成为 LinkedTreeMap
我已经尝试解决这个问题有一段时间了,我找到的所有与此相关的答案都与泛型有关,但我没有使用泛型,而是将类直接传递给gson。
我在这一点上完全迷路了,所以任何指导都会被采纳的
以下是相关的proguard规则:
## ---------------Begin: proguard configuration for Gson ----------
# Gson uses generic type information stored in a class file when working with fields. Proguard
# removes such information by default, so configure it to keep all of it.
-keepattributes Signature
# For using GSON @Expose annotation
-keepattributes *Annotation*
# Gson specific classes
-keep class sun.misc.Unsafe { *; }
# -keep class com.google.gson.stream.**{ *; }
# Application classes that will be serialized/deserialized over Gson
-keep class com.google.gson.examples.android.model.**{ *; }
-keep class com.example.Models.**{ *; }
# Prevent proguard from stripping interface information from TypeAdapterFactory,
# JsonSerializer, JsonDeserializer instances (so they can be used in @JsonAdapter)
-keep class * implements com.google.gson.TypeAdapterFactory
-keep class * implements com.google.gson.JsonSerializer
-keep class * implements com.google.gson.JsonDeserializer
## ---------------End: proguard configuration for Gson ----------
-keep public class MyUserClass
-keep public class UserPosts
