@Dmitri Thanks a lot for spending time to answer my questions at least some doubts are faded off.
1) I understand to use own activity for editing and creating new contacts. 2) Ok, if i avoid ContentObserver even i had that in mind might require something to be running in background which is bad agreed. 3) But, there are two use cases first if there is a button that say sync now and i send request using requestSync() method will it start immediate sync via SyncManager or again it will depend upon SyncManager discretion?? if thats true i cannot start immediate Sync ??. Second use case how would i know if there is a change corresponding to my account in raw_contact utilizing best practice push notification ?? so that i can trigger syncing. thanks Dimitri for your time and ideas On Jan 30, 11:42 am, Dmitri Plotnikov <dplotni...@google.com> wrote: > Hi Himanshu, > > 1) SampleSyncAdapter is still a good source of inspiration.
