I'm stucked with sending an arraylist of objects to another activity. The data to send to, is retrieved via webservice called in an asynctask (SplashScreen activity).
I've already followed some guidelines (i.e. Problem unmarshalling parcelables) but without any luck.
In fact the second activity gets to retrieve the information, and the application works properly, but the exception keeps showing up.
I'd really appreciate any kind of help since it's taking me forever to sort this matter out.
The exception:
01-14 11:31:26.490 2357-3205/? E/Parcelīš Class not found when unmarshalling: com.rebytes.ilistas.MapPacks
