android - 当minifyEnabled为真时，如何在发布版本中修复 "NoSuchFieldException: No field producerIndex"- android？

Question

调试应用程序工作正常。

但是，当使用 minifyEnabled true 构建发布应用程序时，应用程序会崩溃。

当我从 3.4.1 升级到“com.android.tools.build:gradle:3.4.2”的 Gradle 5 时会发生这种情况
(只能在启用了缩小的发布版本中重现。)

在 proguard-rules.pro 中试过这个

-keep public class org.ramanugen.gifex.** { public protected *; }

# Uncomment for DexGuard only
#-keepresourcexmlelements manifest/application/meta-data@value=GlideModule




#
#### RxJava, RxAndroid (https://gist.github.com/kosiara/487868792fbd3214f9c9)
#-keep class rx.schedulers.Schedulers {
#    public static <methods>;
#}
#-keep class rx.schedulers.ImmediateScheduler {
#    public <methods>;
#}
#-keep class rx.schedulers.TestScheduler {
#    public <methods>;
#}
#-keep class rx.schedulers.Schedulers {
#    public static ** test();
#}
#-keepclassmembers class rx.internal.util.unsafe.ArrayQueue*Field {
#    long producerIndex;
#    long consumerIndex;
#}
#-keepclassmembers class rx.internal.util.unsafe.BaseLinkedQueueProducerNodeRef {
#    long producerNode;
#    long consumerNode;
#}

-keep class rx.** { *; }

-renamesourcefileattribute SourceFile
-keepattributes SourceFile,LineNumberTable

忽略 rx 混淆。

在 proguard-rules.pro 中试过这个:

-ignorewarnings
-keep class ** {
    public private *;
}

忽略所有混淆。

日志仍然被混淆。

minifyEnabled 为 false - 应用程序运行良好。(不是我正在寻找的解决方案)

下面是在启用最小化的情况下运行发布构建时的崩溃日志。

正如你在最后一行看到的
NoSuchFieldException: 没有字段 producerIndex
所以我尝试了

-keepclassmembers class rx.internal.util.unsafe.*ArrayQueue*Field* {
 long producerIndex;
}

还是一样的崩溃

Answer 1

你走在正确的轨道上，看起来 ProGuard 缩小了 rxjava 类中的一些重要字段。看起来您正在使用 rxjava 1，它在某些情况下仍然使用反射。

我会将此依赖项添加到我的项目中，以便拥有修复所有可能问题的最新配置:
