Question

I'm developing the chatting application using the SendBird SDK in android studio.

How can I get the list of Open Channels more than 1000?

Answer 1

You can create use an OpenChannelListQuery to traverse through your list of channels in fixed chunks.

OpenChannelListQuery query = OpenChannel.createOpenChannelListQuery();
query.setLimit(30);
query.next(new OpenChannelListQuery.OpenChannelListQueryResultHandler() {
    @Override
    public void onResult(List<OpenChannel> list, SendBirdException e) {
        if (e != null) {
            // Error!
        }
        // list contains the first 30 channels.
    }
});

As long as your query instance is the same, you can call query.next() until you obtain as many channels as you want.

query.next(new OpenChannelListQuery.OpenChannelListQueryResultHandler() {
    @Override
    public void onResult(List<OpenChannel> list, SendBirdException e) {
        // list contains the next 30 channels.
    }
});

Edit: I forgot to mention that the first query.next() must be completely finished before you can call query.next() again. That is, make sure the first onResult() is called before calling query.next() again.
