Remote akka actors on android?
android, sbt-android-plugin, scala
Solution
I got it working with Akka 2.0.2 and Android 2.3.3. What you need to do is:
Workaround that Akka jars include multiple reference.conf at the same path which proguard does not like. Do this by removing the reference.conf from the jars but instead including a custom reference.conf which includes config from both files in the jars.
Configure Proguard to include classes from akka that are referenced by reflection and to ignore warnings about sun.misc.Unsafe. My config: https://gist.github.com/3307987
Upgrade Netty to 3.3.1 (fixes problems with its usage of sun.misc.Unsafe)
Problem
Im trying to make a simple remote connection to a actor using akka as I normally do but Im sure there something else I need to do when using akka from android can anyone help? ``` import akka.actor.Actor.remote // Establish Connection to Remote Actor val server = remote.actorFor(remoteActorID, rIP, rPort) ``` I get te following stack trace: ``` 04-28 09:57:13.114: ERROR/AndroidRuntime(18536): FATAL EXCEPTION: Thread-741 java.lang.ExceptionInInitializerError at akka.actor.Actor$.remote(Actor.scala:115) at edu.spsu.rgoodwin.networking.api.RemoteConnection.<init>(RemoteConnection.scala:18) at edu.spsu.rgoodwin.csrAndroidApp.ClientConfigActivity.routerRegistration(ClientConfigActivity.scala:234) at edu.spsu.rgoodwin.csrAndroidApp.ClientConfigActivity$$anon$1.run(ClientConfigActivity.scala:71) at java.lang.Thread.run(Thread.java:856) Caused by: java.lang.ExceptionInInitializerError at akka.util.ReflectiveAccess$Remote$.<init>(ReflectiveAccess.scala:52) at akka.util.ReflectiveAccess$Remote$.<clinit>(ReflectiveAccess.scala) ... 5 more Caused by: akka.config.ConfigurationException: Event Handler specified in config can't be loaded [akka.event.EventHandler$DefaultListener] due to [java.lang.ClassNotFoundException: akka.event.EventHandler$DefaultListener] [localhost_0e3e4c40-913a-11e1-b984-660379e93466] at akka.event.EventHandler$$anonfun$1.apply(EventHandler.scala:231) at akka.event.EventHandler$$anonfun$1.apply(EventHandler.scala:223) at scala.collection.LinearSeqOptimized$class.foreach(LinearSeqOptimized.scala:59) at scala.collection.immutable.List.foreach(List.scala:45) at akka.event.EventHandler$.<init>(EventHandler.scala:223) at akka.event.EventHandler$.<clinit>(EventHandler.scala) ... 7 more Caused by: java.lang.ClassNotFoundException: akka.event.EventHandler$DefaultListener at java.lang.Class.classForName(Native Method) at java.lang.Class.forName(Class.java:217) at java.lang.Class.forName(Class.java:172) at akka.util.ReflectiveAccess$.getClassFor(ReflectiveAccess.scala:222) at akka.event.EventHandler$$anonfun$1.apply(EventHandler.scala:225) ... 12 more Caused by: java.lang.NoClassDefFoundError: akka/event/EventHandler$DefaultListener ... 17 more Caused by: java.lang.ClassNotFoundException: akka.event.EventHandler$DefaultListener at dalvik.system.BaseDexClassLoader.findClass(BaseDexClassLoader.java:61) at java.lang.ClassLoader.loadClass(ClassLoader.java:501) at java.lang.ClassLoader.loadClass(ClassLoader.java:461) ```
