Hello,

I was wondering what is the standard way to backup / restore application options (scenario: user backups options on memory card, reinstalls OS, reinstalls app, restores options)

I'd rather not implement my own encode / decode routines if possible.

I have seen several approaches used in real-world apps:
* csv like data file
* binary storage (Berry Weather)
but I am not aware about how they were implemented.

Any ideas / suggestions ?

Any experts around ? 

I am looking for something similar to Java SE serialization ...

Here is the 'official' way:

This works if people use Desktop Manager to switch devices. 

I think most people will write their own serialization code to convert from the Objects to a byte form (as you have seen csv, or own format, or XML) and then put that somewhere - like your own server for a network aware app or SD Card.  This approach works regardless of the method the user users to switch devices.

Peter, thanks for your response.

I am aware of the Desktop Manager approach, but was looking for something more general.

It seems that I will also have to go this way ...

I will leave this thread open for another couple of days in case that anybody else has something to say.
