i have solved problems listed in stackoverflow forums given below

akka on android multiple reference.conf

akka on android

but still app crashes. not using scala/scaloid. using akka lib java.

i have uploaded full code here

i have added following akka jars libs folder 1. akka-actor_2.11-2.3.11.jar 2. config-1.2.1.jar 3. scala-library-2.11.5.jar

what might have gone wrong. please guide me in resolving issue.

looks issue library dependency, suppose dependency not given in build.grade
