android bound service with scala - cant get Binder.getService working -

i trying android app developed in scala work. error during compile

[error] testservice.scala:49: error: type mismatch; [info]     found   : .services.testservice.type (with underlying type object .services.testservice) [info]     required: .services.testservice 

service

class testservice extends service {   val mbinder: ibinder = new testservice.testservicebinder   val list  = list("linux", "android", "ios", "wp")    override def oncreate    {     toast.maketext(this, tag + " created", toast.length_long).show;     log.d(tag, "oncreate");   }    override def ondestroy   {     toast.maketext(this, tag + " destroyed", toast.length_long).show;     log.d(tag, "oncreate");   }    override def onstart(intent: intent, startid: int)   {     toast.maketext(this, tag + " started", toast.length_long).show;     log.d(tag, "onstart");   }    override def onbind(intent: intent): ibinder = mbinder    def getlist: list[string] = list  }  object testservice {   class testservicebinder extends binder   {     def getservice: testservice = testservice.this   } } 

activity

class homeactivity extends activity findview {    private final val tag = "homeactivity"    lazy val buttontest: button = findview[button](r.id.testbutton)    private var mservice: testservice = _   private var mbound: boolean = false    val mconnection: serviceconnection = new testserviceconnection    override def oncreate(savedinstancestate: bundle)   {     super.oncreate(savedinstancestate)     setcontentview(r.layout.main)      buttontest.setonclicklistener(buttontestonclicklistener)      log.i(tag, "oncreate")   }    override def onstart   {     super.onstart     val intent: intent = new intent(this, classof[testservice])     bindservice(intent, mconnection, context.bind_auto_create);   }    override def onstop   {     super.onstop     if(mbound)     {       unbindservice(mconnection)       mbound = false     }   }    object buttontestonclicklistener extends view.onclicklistener   {     def onclick(v: view)     {       if(mbound)       {         toast.maketext(v.getcontext, mservice.getlist.tostring, toast.length_long).show       }     }   }    class testserviceconnection extends serviceconnection   {     def onserviceconnected(classname: componentname, service: ibinder)     {       val binder = (new testservice.testservicebinder).asinstanceof[testservicebinder]       mservice = binder.getservice       mbound = true     }      def onservicedisconnected(classname: componentname)     {       mbound = false     }   }  } 

i hope can me or give me tutorial how bound services in scala work. assistance. chris

edit line 49 is: def getservice: testservice = testservice.this

i'm not sure understand why getservice looks looks. why not way:

def getservice: testservice = new testservice 

the second thing not understand following line

val binder = (new testservice.testservicebinder).asinstanceof[testservicebinder] 

why need asinstanceof here?

edit think have in android documentation. in companion object (like have implemented it) can not access this.

class localservice extends service {    private final val localbinder = new localbinder()    class localbinder extends binder {       def getservice: localservice = localservice.this   } }
