Question

我正在为我的项目使用来自 Proguard 的代码，下面的代码在我的 proguard-rules.pro 中：

# Retrofit

但是当我运行我的 apk 让我崩溃时 :

Answer 1

您需要保留您的模型，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.** { *; }

Answer 3

根据改造 3.8.1

-dontwarn okio.**
-dontwarn javax.annotation.**
-dontwarn retrofit2.Platform$Java8

Answer 4

当前的 Proguard 规则（截至 12/18）是 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

Answer 5

对于 retrofit 和 GSON，您需要在 proguard-rules.pro 文件

中添加以下规则

For Retrofit Please add below rules

# 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

For GSON Please add below rules

##--- 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 ----

在您的数据类之前使用 @keep 注释，以便保留它们。这消除了使用单独的 Proguard 规则的需要。

Denotes that the annotated element should not be removed when the code is minified at build time. This is typically used on methods and classes that are accessed only via reflection so a compiler may think that the code is unused.

@Keep
data class Listing(
    val id: String = "",
    val name: String = ""
)

来源：https://developer.android.com/reference/kotlin/androidx/annotation/Keep

Answer 7

我注意到为每个类添加 @Keep 的注释，确实它修复了所有内容，但也没有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、响应和它们需要（保存数据）的类放入某个文件夹（或文件夹，如果你想更有条理的话），并在“proguard-rules.pro" 文件:

-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 *;
}

此外，如果你构建一个混淆库，你应该把这个（第二个，不是带有“allowobfuscation”的那个）放在“consumer-rules.pro”中，并确保你有这个在里面它的 gradle 文件：

    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'
        }
    }
