Filtering by geolocation

[Dobromir]

Hello everyone,
what I need is that function over there in Javascript SDK for filtering near geo point. 

var query = new Everlive.Query();
query.where().nearSphere('Location', [23.379068, 42.650601], 100, 'km');

Is this functionality available in Android SDK?
Thank you

Hello Dobromir,

The Android SDK currently does not expose querying on GeoPoint fields out of the box. In order to achieve this you need to send a header with the filter to the REST API of  Backend Services as explained here, by appending it as an "X-Everlive-Filter" header to the request.

For example:

public ArrayList<Book> GetBooks(EverliveApp app) {
    RequestResult<ArrayList<Book>> requestResult = app.workWith().
                data(Book.class).
                getAll().beforeRequest(new GenericCallbackAction<Request>() {
            @Override
            public void invoke(Request request) {
                request.getHeaders().put("X-Everlive-Filter", "Stringified filter value here");
            }
        }).executeSync();

    return requestResult.getSuccess() ? requestResult.getValue() : null;
}

Let me know if this works for you and if you have questions.
