How to keep RMS after installing a new version?

Question

I have an j2me application installed on a Nokia S40. Some configuration data is stored in the RMS. Is it possible to overwrite the installed app with a new version? How to keep RMS in the new version?

If it is possible can it be set as a default operation when upgrading to avoid the user accidentally delete the data?

Answer 1

If your phone automatically deletes the RMS database without asking the user, it's a huge bug that goes against the MIDP specifications.

I assume you are using a retail phone, not a prototype.

It's always worth checking if the firmware can be upgraded with nokia PC tool.

If the upgrade process asks the user whether to delete old RMS data, there is probably little you can do to prevent the question being asked.

It's usually good practice to synchronize configuration data on a remote server and re-download it when it becomes unavailable.
