Android IPC Remote service call display Error

I want to make one demo application regarding the IPC communication .(Communication between Service). I am using AIDL for that .

I found most of tutorial the RemoteService and Client are in same package .

I actually do it separately ,While passing the object I am using ParcelableMethod and facing Error ...

It said like The RemoteService Signature unable to find your class.. I displayed my Logcat Below also : If you have any solution please guide me ...or any interdependent server client service tutorials or documents..

LOGCAT:

Thanks;

I do not know exactly but it seems that you did not put aidl in your client application. You should put aidl in Service and in the Client application.
