通过Proguard获得警告(与外部库一起使用) [英] Getting Warnings With Proguard (With External Libraries)

问题描述

我已经启用了Proguard，并且我正在尝试构建APK，并且收到很多警告，并且不知道如何解决它们.

I have enabled Proguard, and i'm trying to build the APK, and i'm getting a lot of warnings and don't know how to solve them .

我正在使用Retrofit，Jsoup和其他库存库，收到以下警告:

I'm using Retrofit, Jsoup and other stock libraries, I'm getting the following warnings :

这是我的监护人:

   public static final android.os.Parcelable$Creator *;
 }

 ##---------------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


 # Gson specific classes
 -keep class com.abohani.tdroms.SharedPreferencesTools { *; }
 #-keep class com.google.gson.stream.** { *; }


 # Application classes that will be serialized/deserialized over Gson
 -keep class com.abohani.tdroms.** { *; }

推荐答案

使用ProGuard时，您必须始终解决所有警告.

When you use ProGuard you have to always resolve all warnings.

这些警告告诉您这些库引用了一些代码，并且没有相关的源代码.那可能也可能不行.这取决于是否调用了有问题的代码.

These warnings tell you that the libraries reference some code and there are no sources for that. That might and might not be ok. It depends if the problematic code ever get called.

在这种情况下，可以忽略针对Okio和Retrofit2的警告.包java.nio.*在Android上不可用，并且永远不会调用.您可以放心地忽略这些警告.同样，将不使用Java 8类.

In this case warnings for Okio and Retrofit2 can be ignored. Package java.nio.* isn't available on Android and will be never called. You can safely ignore those warnings. Also Java 8 classes won't be used.

将此添加到ProGuard配置中，它应该可以解决您的问题:

Add this to your ProGuard configuration, it should fix your problem:

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