Android Question KVS module to KVS Library[Solved]

[Roger Daley]

Hi All,

More out of curiosity than need for a solution.

I have an app using KVS 1.01 module, I attempted change this to KVS library and failed.

1. Remove KVS module from project
2. Add KVS library [NOT KVS2]
3. Change all KVS.getObject and all KVS.putObject lines to KVS.get and KVS.Put.
4. Compile and run with the resulting error log.

5. Restore KVS Module all working.

Something in me says "It ain't broke, don't fix it" but it is a puzzle.
Any ideas? Is there post that I've missed?

Regards Roger

The old kvs if I remember correctly uses KVS.putsimple() and KVS.getsimple()

It is Keyvaluestore2 that uses only PUT and GET

You will need to start with a new database (or add code that converts the old database). The old version with PutSimple / GetSimple is not compatible with the later versions.

Thanks Erel, mystery solved.
Unless someone has code to convert dB from V1.01 to dB for KVS library version lying around l will leave it alone.

No reason to convert. The old one is fine. Do use the new one with your next app.
