'Serializable' is ill-suited for persistence to disk. 'Parcelable' isn't much better. They're intended for in-process or inter-process transfers of data, not persistence. Don't use them.
'Serializable', in particular, imposes a huge maintenance burden, in that it locks down implementation of the class /ad aeternam/. Read Joshua Bloch's entire chapter on serialization in /Effective Java/ for the relevant warnings, dangers and gotchas. There are many. Really. Make sure you really know what you're doing before using 'Serializable'. That said, the methods that support serialization can work around your trouble, potentially. You sort of hand-roll the parts not provided upstream for you by the API. <http://download.oracle.com/javase/7/docs/api/java/io/Serializable.html> Don't walk into serialization without doing your homework first. Lesson one: it isn't good for persistence. Lesson two: it isn't cheap. Or maybe it's the other way around. -- Lew On Wednesday, October 5, 2011 8:20:52 AM UTC-7, Jean-Michel wrote: > > No, I am serialising to disk. > > Do you think it could work out? > > Any idea how to use Parcelable ? > > Many thanks, > Jean-Michel > > On 5 oct, 16:43, Daniel Drozdzewski <daniel.dr...@gmail.com> > wrote: > > > Now luckily for you, Location in Android implements Parcelable > > interface, which could be of help, depending where are you sending to > > and receiveing from your Leg/Location related data. > > If it is within the same machine between a service and an activity, > > then you are fine.
