I have followed the [BasicSyncAdapter](https://github.com/googlesamples/android-BasicSyncAdapter) example in the google samples and I wonder why a default periodic sync (sync interval 86400 secs or 24h) is even created if I [comment out the call to `addPeriodicSync()` function in the code](https://github.com/googlesamples/android-BasicSyncAdapter/blob/master/Application/src/main/java/com/example/android/basicsyncadapter/SyncUtils.java#L63).

I find no documentation whatsoever that creating a SyncAdapter and the stub code (SyncService, Authenticator account etc.) also creates a periodic sync with that default sync interval. 

My Question: Is it possible to create a SyncAdapter without such default periodic sync?

Thanks.

BTW, this is how I detect the presence of periodic syncs.

```
java.util.List<PeriodicSync> periodicSyncsList = ContentResolver.getPeriodicSyncs(myaccount, CONTENT_AUTHORITY);
Log.d(TAG, "Number of syncs in the periodicSyncsList = " + periodicSyncsList.size());
for (PeriodicSync p : periodicSyncsList) {
    Log.d(TAG, p.toString());
}

```
