Question

我的Android项目中使用的其中一个库包含Akka及其相应的Scala依赖项。每当我运行该项目时，我都会收到以下错误消息：

在我的proguard文件中，我添加了以下规则以尝试缓解此问题：

## akka START
-keep class com.typesafe.**
-keep class akka.**
-keep class scala.collection.immutable.StringLike {
    *;
}
-keepclasseswithmembers class * {
    public <init>(java.lang.String, akka.actor.ActorSystem$Settings, akka.event.EventStream, akka.actor.Scheduler, akka.actor.DynamicAccess);
}
-keepclasseswithmembers class * {
    public <init>(akka.actor.ExtendedActorSystem);
}
-keep class scala.collection.SeqLike {
    public protected *;
}


  -keep class akka.actor.LightArrayRevolverScheduler { *; }
  -keep class akka.actor.LocalActorRefProvider { *; }
  -keep class akka.actor.CreatorFunctionConsumer { *; }
  -keep class akka.actor.TypedCreatorFunctionConsumer { *; }
  -keep class akka.dispatch.BoundedDequeBasedMessageQueueSemantics { *; }
  -keep class akka.dispatch.UnboundedMessageQueueSemantics { *; }
  -keep class akka.dispatch.UnboundedDequeBasedMessageQueueSemantics { *; }
  -keep class akka.dispatch.DequeBasedMessageQueueSemantics { *; }
  -keep class akka.actor.LocalActorRefProvider$Guardian { *; }
  -keep class akka.actor.LocalActorRefProvider$SystemGuardian { *; }
  -keep class akka.dispatch.UnboundedMailbox { *; }
  -keep class akka.actor.DefaultSupervisorStrategy { *; }
  -keep class akka.event.Logging$LogExt { *; }

## akka END

我仍然无法让项目编译并成功运行。我能做些什么才能让它发挥作用？

Answer 1

最新版本的Akka（和Scala）需要Java 8，据我所知，它无法在仅支持Java 7或6的android上运行。

让Android在Scala中发挥出色
