I have followed the developpers guide about Transferring Data Using Sync Adapters .
When my app is connectected to internet , there is no problem , the SyncAdapter is called.
But if i'm connected to a LAN instead , the sync never happen. It is problematic for me because my app can work online and get data from a server on the web or offline , in a private network, and get data from a server on the LAN.
I can't find any mention of a mandatory internet connection in the documentation.
Should i forget the sync framework and use AlarmManager instead or the sync framework can work offline ?
I already read this question but there is no real answer
