【问题讨论】：
【参考方案1】：您需要保留模型，不要混淆它们。我看到你的模型有错误，sqlite 不能在你的模型上工作。应该是这样的：
-keep class package.to.yourmodels.** *;
【讨论】：
只有这个对我有用。我也试过这个***.com/questions/35506111/…。但只有肉山山解决方案对我有用 谢谢！我花了太多时间才发现这个问题，但现在一切正常【参考方案2】：2021解决方案
在您的数据类之前使用@keep 注释，以便保留它们。这消除了拥有单独的 Proguard 规则的需要。
表示在构建时缩小代码时不应删除带注释的元素。这通常用于仅通过反射访问的方法和类，因此编译器可能会认为代码未使用。
@Keep
data class Listing(
val id: String = "",
val name: String = ""
)
来源：https://developer.android.com/reference/kotlin/androidx/annotation/Keep
【讨论】：
如果我有 100 个数据类怎么办？一次循环遍历它们？这不合逻辑！ 这有效（在请求和响应的主体对象上实现），但为什么它保留类的名称和字段名称？我不能让他们混淆吗？例如，我看到@SerializedName("country") val country: String? 的所有内容都相同。我至少不能混淆字段名称吗？
@blueware 确实可行，但正如您所说，这很烦人，而且我发现它不会改变任何东西的名称。这就是我发现的工作：***.com/a/66670232/878126【参考方案3】：
解决了我的问题：
# Add project specific ProGuard rules here.
# By default, the flags in this file are appended to flags specified
# in C:\Users\asheq\AppData\Local\Android\Sdk/tools/proguard/proguard-android.txt
# You can edit the include path and order by changing the proguardFiles
# directive in build.gradle.
#
# For more details, see
# http://developer.android.com/guide/developing/tools/proguard.html
# Add any project specific keep options here:
# If your project uses WebView with JS, uncomment the following
# and specify the fully qualified class name to the javascript interface

【讨论】：
这似乎有很多与问题无关的规则。我应该使用哪些部件？【参考方案4】：根据 rerofit 3.8.1
-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn retrofit2.Platform$Java8
【讨论】：
-dontwarn javax.annotation.** 我错过了这一行。非常感谢。【参考方案5】：当前的 Proguard 规则（截至 12 月 18 日）为 here。
# Retrofit does reflection on generic parameters. InnerClasses is required to use Signature and
# EnclosingMethod is required to use InnerClasses.
-keepattributes Signature, InnerClasses, EnclosingMethod
# Retain service method parameters when optimizing.
-keepclassmembers,allowshrinking,allowobfuscation interface *
@retrofit2.http.* <methods>;
# Ignore annotation used for build tooling.
-dontwarn org.codehaus.mojo.animal_sniffer.IgnoreJRERequirement
# Ignore JSR 305 annotations for embedding nullability information.
-dontwarn javax.annotation.**
# Guarded by a NoClassDefFoundError try/catch and only used when on the classpath.
-dontwarn kotlin.Unit
# Top-level functions that can only be used by Kotlin.
-dontwarn retrofit2.-KotlinExtensions
【讨论】：
【参考方案6】：我注意到为每个类添加@Keep 的注释确实可以解决所有问题，但也不会更改我设置的所有内容的名称。
所以，我的解决方案有点不同：
将所有请求、响应和他们需要（保存数据）的类放入某个文件夹（或文件夹，如果您想更有条理），并在“proguard-rules.pro”文件中创建 Proguard 规则：
-keep,allowobfuscation class com.your_library.rest_objects.** *;
或者，如果由于某种原因这不起作用，您可以使用它（来自here）：
-keep public class *
public protected *;
另外，如果你构建一个混淆库，你应该把它（第二个，而不是带有“allowobfuscation”的那个）放在“consumer-rules.pro”中，并确保在它的 gradle 文件中有这个：
buildTypes
release
minifyEnabled true
proguardFiles getDefaultProguardFile('proguard-android-optimize.txt'), 'proguard-rules.pro'
// https://developer.android.com/studio/projects/android-library
consumerProguardFiles 'consumer-rules.pro'
【讨论】：
【参考方案7】：对于 retrofit 和 GSON，您需要在 proguard-rules.pro 文件中添加以下规则
对于改造请添加以下规则
# Retrofit
-dontwarn retrofit2.**
-dontwarn org.codehaus.mojo.**
-keep class retrofit2.** *;
-keepattributes Signature
-keepattributes Exceptions
-keepattributes *Annotation*
-keepattributes RuntimeVisibleAnnotations
-keepattributes RuntimeInvisibleAnnotations
-keepattributes RuntimeVisibleParameterAnnotations
-keepattributes RuntimeInvisibleParameterAnnotations
-keepattributes EnclosingMethod
-keepclasseswithmembers class *
@retrofit2.* <methods>;
-keepclasseswithmembers interface *
@retrofit2.* <methods>;
# Platform calls Class.forName on types which do not exist on Android to determine platform.
-dontnote retrofit2.Platform
# Platform used when running on RoboVM on iOS. Will not be used at runtime.
-dontnote retrofit2.Platform$IOS$MainThreadExecutor
# Platform used when running on Java 8 VMs. Will not be used at runtime.
-dontwarn retrofit2.Platform$Java8
# Retain generic type information for use by reflection by converters and adapters.
-keepattributes Signature
# Retain declared checked exceptions for use by a Proxy instance.
-keepattributes Exceptions
对于GSON请添加以下规则
##--- Begin: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.** *;
# 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
# keep enum so gson can deserialize it
-keepclassmembers enum * *;
# Application classes that will be serialized/deserialized over Gson
-keep class net.mreunionlabs.wob.model.request.** *;
-keep class net.mreunionlabs.wob.model.response.** *;
-keep class net.mreunionlabs.wob.model.gson.** *;
##--- End:GSON ----
##--- End:GSON ----
