I am a new user of the b4a hence my questions about the syncing usage. I've been developer for many years already and thought that b4a probably has a syncing library already from local storage databases to central repository database.
Anyway, I am looking at two options to solve the problem on my side if I am going to use the b4a to build the android app.
1. I'm currently looking at a paid solution offered by the handapps.com . Richard has been great to explain how their licensing works. Their syncstudio covers pretty much everything that I need for my solution. Indeed it comes with a cost but nothing scary. They have done a pretty good job from what I was able to see so far.
2. I can quickly develop a syncing solution by simply comparing unique ID field from the local storage table against the server equivalent table and then do the updates to the central database. It's a simple solution which could work, however option 1 works better because the developer has greater control over everything that happens with the data.
Not sure if something else exists by the way
