You should not close Realm instance in getLogs() if you will use RealmResults outside of the method.

do i need to create realm instance in onCreate if calling from activity instead of creating instances in each method when calling from activity?

yes.

[zaki50]

Realm instance returned from Realm.getDefaultInstance() is reference counted in each thread. When the Realm.getDefaultInstance() iscalled, the count is incremented and close() decrements it. close() actually closes the Realm instance only when the counter reaches 0.

So, if you already called Realm.getDefaultInstance() and corresponding close() is not yet called, realm.close() in the getTimeCard() doesn’t close actually.
