ProGuard 不能与 okhttp 一起使用

Question

ProGuard 无法与 okhttp 配合使用，我不断收到以下警告：

Warning:com.squareup.okhttp.internal.huc.HttpsURLConnectionImpl: can't find referenced method 'long getContentLengthLong()' in program class com.squareup.okhttp.internal.huc.HttpURLConnectionImpl
Warning:com.squareup.okhttp.internal.huc.HttpsURLConnectionImpl: can't find referenced method 'long getHeaderFieldLong(java.lang.String,long)' in program class com.squareup.okhttp.internal.huc.HttpURLConnectionImpl
Warning:com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpsURLConnection: can't find referenced method 'long getContentLengthLong()' in program class com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpURLConnection
Warning:com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpsURLConnection: can't find referenced method 'long getHeaderFieldLong(java.lang.String,long)' in program class com.squareup.okhttp.internal.huc.JavaApiConverter$CacheHttpURLConnection
Warning:there were 4 unresolved references to program class members.
         Your input classes appear to be inconsistent.
         You may need to recompile the code.
         (http://proguard.sourceforge.net/manual/troubleshooting.html#unresolvedprogramclassmember)

这些是我对 okhttp 和改造的 proguard 设置：

-dontwarn rx.**

-dontwarn okio.**

-dontwarn com.squareup.okhttp.*

-dontwarn retrofit.appengine.UrlFetchClient


-keep class retrofit.** { *; }

-keepclasseswithmembers class * {

@retrofit.http.* <methods>; }

-keepattributes Signature 
-keepattributes *Annotation*

这可能与 Android Studio 1.0 中对 ProGuard 的更改有关吗？

我尝试了相关问题的答案，但他们只建议使用我已有的设置。

Answer 1

这对我有用：

您必须在您的 proguard-rules.pro 中添加这两行：

-keep class com.squareup.okhttp.** { *; }

-keep interface com.squareup.okhttp.** { *; }

---

完整的 proguard-rules.pro 文件如下所示：

-dontwarn rx.**

-dontwarn okio.**

-dontwarn com.squareup.okhttp.**
-keep class com.squareup.okhttp.** { *; }
-keep interface com.squareup.okhttp.** { *; }

-dontwarn retrofit.**
-dontwarn retrofit.appengine.UrlFetchClient
-keep class retrofit.** { *; }
-keepclasseswithmembers class * {
    @retrofit.http.* <methods>;
}

-keepattributes Signature
-keepattributes *Annotation*

我终于能够解决这个问题了。

我遇到的警告实际上是没有意义的，可以忽略。

相反，我忘了不要混淆我的模型类：

-keep class com.example.datamodel.** { *; }

更改后一切正常。

Answer 3

OkHttp

-keepattributes 签名

-keepattributes 注解

-保持类正常http3.** { *; }

-保持界面正常http3.** { *; }

-dontwarn okhttp3.**

Answer 4

这个配置对我有用。对于所有封装了子包的子类，使用** 而不是*

-dontwarn org.xmlpull.v1.**
-dontwarn com.squareup.**
-keep class com.squareup.** { *; }

Answer 5

将此添加到您的 proguard 设置中：

-dontwarn com.squareup.okhttp.internal.huc.**

我认为可以安全地假设您没有使用 com.squareup.okhttp.internal 中的任何类，因为这是您的警告的来源。

Answer 6

万一还有人掉进这里。所需的 Proguard 配置在 OkHttp 主存储库中记录和维护：

Answer 7

对于okhttp3，you needthe following：

# JSR 305 annotations are for embedding nullability information.
-dontwarn javax.annotation.**

# A resource is loaded with a relative path so the package of this class must be preserved.
-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase

# Animal Sniffer compileOnly dependency to ensure APIs are compatible with older versions of Java.
-dontwarn org.codehaus.mojo.animal_sniffer.*

# OkHttp platform used only on JVM and when Conscrypt dependency is available.
-dontwarn okhttp3.internal.platform.ConscryptPlatform

Answer 8

# JSR 305 annotations are for embedding nullability information.
-dontwarn javax.annotation.**

# A resource is loaded with a relative path so the package of this class must be preserved.
-keepnames class okhttp3.internal.publicsuffix.PublicSuffixDatabase

# Animal Sniffer compileOnly dependency to ensure APIs are compatible with older versions of Java.
-dontwarn org.codehaus.mojo.animal_sniffer.*

# OkHttp platform used only on JVM and when Conscrypt dependency is available.
-dontwarn okhttp3.internal.platform.ConscryptPlatform

Answer 9

okhttp3 Proguard 规则

这里是 okhttp3 Proguard 的正确格式。

-keepattributes Signature  
-keepattributes Annotation  
-keep class okhttp3.** { *; }  
-keep interface okhttp3.** { *; }  
-dontwarn okhttp3.**  
-dontwarn okio.**
