Synchronization between devices about financius HOT 22 OPEN

Hi, I would be glad to help here by developing a server and an API for synchronization between devices.

Regarding handling sync and accounts for it, this might help for Android side:

I will be doing this on GAE

Would you consider providing an API so that people (me for starters) would develop their own web clients? I loved the Android app and would like to have a web app that would be in sync with my smartphone, however I never used Google App Engine or have any aspirations towards it.

Well that depends, because AppEngine is not free when you get a lot of requests :) But it's an interesting proposition. It will depend on if I can fit in that "free" range

from financius.

You'd probably need to crunch some numbers of users and check the free quota and maybe make it a subscription (monthly/yearly). Wouldn't there be a chance to use users Google Drive storage for saving their data ? So when changes occur locally, the sync adapter (as I pasted the samples above) syncs to the Drive Storage. The sync adapter then updates the state on other devices with added Financius account (authenticator sample above) periodically, with other sync adapters, or per app launch.

I think that this can be achieved easily using Google Cloud Messaging and Push Notifications.
After an initial sync using a Google Drive backup you just need to push Transactions to other devices through a Push Notification so you don't have to handle a large set of data but just push around simple JSONs encoded transactions.
You don't need to store all data on your server but just a simple database that keeps track of users and their devices.

That would not work :)

@mvarnagiris : Which suggestion, mine or @panz3r's :]

from financius.

@panz3r 's :) Using Google Drive is a possibility. But I want to use GAE so we could have "family budgets". Different google accounts using same Financius account for spending or something like that

from financius.

Ah, yes using multiple accounts would be impossible to access 1 ''shared'' storage on Drive private app space. How many users are actively using the app now anyway (kinda don't have a perspective of how large scale this operation would be)?

from financius.

Past 30 days 21,576 active users

Shall we work together ?

We are using family accounting and google drive would be sufficient - I created a google account we all have on our mobile devices. Anyhow, I am VERY interested in this feature and I would be willing to pay some subscription fee for having this at hand. Our usual number of monthly transactions is around 100 with peak months getting at 120 and summer months with only 80 txns per month.

Would love to have this feature. IMO just a scheduled restore-merge-backup to selected file in Google Drive would be sufficient (at least for the start).

Essential feature that app is currently missing. Would gladly pay to use this feature in your app.
