How to replace local files with updated files from a server?

[rwblinn]

Dear All,

building an app which uses several local sqlite db files. These are stored under File.DirRootExternal.

What is the best way to replace local files by updated files which are stored on a server?

In addition, is there guidance on how to implement a "check for updates" function.

Appreciated,
Rob

Which type of server are you using?
There are several options.

In addition, is there guidance on how to implement a "check for updates" function.

If your app is a Google Play app then it will be managed by Google Play.

Update data from server to local db on an app

Hi Erel,

I am looking for a solution using a server hosted by my third party web provider. Like transfer from http://mywebadress/myfile to my local app/storagearea/myfile.

Thank You

Hi
I have done that.
I simply put a record in server-database with a version no.
The app contact the server and fetch the record and all it does is a simple compare.
Depending on the result you will know if there is a need for downloading...

Consider if there really is a need for local storage.
Perhaps your app can ask the server and fetch whatever is needed "on the fly".
If there is only small records you will probably not notice the small delay...

Good luck with your project!

That is a good idea as one route. The other I found out, is using httputils2.

Thanks for your help.

Put a record in server-database with a version No.
Put a variable in your app with version No.
With every startup of your app contact the server and fetch the record and simply compare the two.
Depending on the result you will know if there is a need for downloading...
Thats all to it!
