android - 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.

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*
