Java SDK AVQuery查询不到

AVQuery<AVObject> avQuery = new AVQuery<>("Feeds");
        avQuery.orderByDescending("createdAt");
        avQuery.whereEqualTo("likedCount", 20);
//        avQuery.limit(10);
//        avQuery.include("owner");
        avQuery.findInBackground().subscribe(new Observer<List<AVObject>>() {
            @Override
            public void onSubscribe(Disposable d) {
                Toast.makeText(getApplicationContext(),d.toString(),Toast.LENGTH_LONG).show();
            }

            @Override
            public void onNext(List<AVObject> list) {
                feedList.addAll(list);
                feedAdapter.notifyDataSetChanged();
            }

            @Override
            public void onError(Throwable e) {

            }

            @Override
            public void onComplete() {

            }

每次查询都会跳到onSubscribe(Disposable d)
