@Dmitri Yes i created my account when i go to Account & sync section through settings and after adding my account , sync gets enabled in DDMS i can see SyncManager gets called twice once on setIsSyncable and on setSyncAutomatically but My Service associated with SyncAdapter does not gets started and also i dont reach to onPerformSync immediately when i explicitly call requestSync.
