I want to develop an app in which i will sync data between app & server.as of now i enter some data to app & save it locally when it is saved in sqlite then i send the same data to server.In this way i can view the data even if there is no internet connection.But now issue is user can also update or update the data from server end.So every time i should get the latest data.

1.Should i run a service which check every time number of records on sqlite & server.If there is difference then show latest data.

Please tell the solution.

could be done using timestamps. Client asks server for new data including the timestamp in the request. Server delivers new data since the transfered timestamp. For Realtime Updates, you could use something like socket.io (or websockets in general). So the server can push updates to the client – aschattney Sep 19 '15 at 16:58
but time can be different for server & local app.?@aschattney – TechChain Sep 19 '15 at 16:59
unix timestamp should be the same, am i wrong? – aschattney Sep 19 '15 at 17:01
If you dont mind relying on a BaaS, then parse.com supports something like this using what they call a Local Datastore – cYrixmorten Sep 19 '15 at 17:03
i have no idea regarding this – TechChain Sep 19 '15 at 17:07
No i don't want to use baas? I heard of sync adapters & gcm which should be used – TechChain Sep 19 '15 at 17:09
