Check whether local datastore is empty

Question

I am learning to build android app using Parse. I need to check if Parse local datastore is empty, i.e there are currently no pinned objects on the datastore.

Is there a simple way to do it ?

Answer 1

There is. Query the local datastore and check if the number of returned objects == 0

Answer 2

The fast and simple way to do it is:

public boolean isEmpty(String className) {
     ParseQuery<ParseObject> query = ParseQuery.getQuery(className);
     query.fromLocalDatastore();
     return query.count() == 0;
}

This only works for checking single class.
