General
1

Hi ,
I try to fetch 50 records at a time from backendless table and i am not able to find all that in single query.

Currently i am doing this code :
Backendless.Data.of(History.class).find(dataQuery, new LoadingCallback&lt;BackendlessCollection&lt;History&gt;>(getActivity(), "Loading...", true) {
 @Override
 public void handleResponse(BackendlessCollection&lt;History&gt; historyBackendlessCollection) {
 
// here i am getting record form server and try to add in arraylist but i get only 10 record in this list
 listitem.addAll(historyBackendlessCollection.getCurrentPage());
 
 super.handleResponse(historyBackendlessCollection);
 }
});

here i am not able to get all record how to do these ?
Please help to solve this .

Add this code before you load any data:

QueryOptions queryOptions = new QueryOptions();
queryOptions.setPageSize( 50 );
dataQuery.setQueryOptions( queryOptions );

Ok ,

Thanks Mark ,
It’s work and helpful for me.

It is not possible to give pagesize > 100 ?

5

No, 100 is the maximum.

6

So if i want more than 100 then what i have to do ? Is there any other way to do that?

Use paging API
