I am getting this error message but I don't see anything in the error log
that seems related to classloaders:

Maybe the issue is related to proguard. I have included a very minimal
application.conf file and I think proguard is cutting the configuration
file when I install the application. So the app crashes at runtime because
it cannot find such configuration file.
Once I installed get the apk file, I have unzipped it and I cannot see the
application.conf file that is supposed to be there. I am using:
scala 2.10.3
akka-actor 2.3.0-RC2
sbt 0.13.2-M1
My plugins are these
addSbtPlugin("com.hanhuy.sbt" % "sbt-idea" % "1.6.0")
addSbtPlugin("com.hanhuy.sbt" % "android-sdk-plugin" % "1.2.8")
My minimal application.conf has:
akka {
loglevel = DEBUG
}
I don't know how to tell proguard to keep/include this configuration file.
-include application.conf
doesn't work because proguard chokes with my configuration file.
I really need some help please!! I am very frustrated trying to make this
to work. Maybe I need to something special in my proguard-project.txt, or
my project/Build.scala.
I also tried the approach followed in the safe-metronome project and I
failed:
