android - 内存不足错误RxAndroid + RxJava + Retrofit2

我是使用RxAndroid和RxJava的新手。我正在使用RxJava + Retrofit2进行GET请求。我正在使用以下代码执行约1500个GET请求，并出现内存不足错误。但是这次相同的代码只进行了翻新，没有RxAndroid，并且可以正常工作。所以我的结论是我在RxAndroid中做错了什么。您能帮我解决我所缺少的吗？

代码样例:

Subject<Story> mStoryEmitter = PublishSubject.create();

private void getStory(int storyID) {
    HNApi.Factory.getInstance().getStory(storyID).subscribeOn(Schedulers.io())
            .observeOn(AndroidSchedulers.mainThread())
            .subscribe(getStoryObserver());
}

mStoryListEmitter.subscribe(new Observer<List<Integer>>() {
    @Override
    public void onSubscribe(Disposable d) {}

    @Override
    public void onNext(List<Integer> value) {
        if(mRecyclerView != null) {
            mRecyclerView.setAdapter(null);
            if(mAdapter != null) {
                mAdapter.clear();
                mAdapter = null;
            }
        }
        mAdapter = new SimpleRecyclerViewAdapter();
        mRecyclerView.setAdapter(mAdapter);

        for(Integer storyID : value) {
            getStory(storyID);
        }
    }

    @Override
    public void onError(Throwable e) {}

    @Override
    public void onComplete() {}
});

private DisposableObserver<Story> getStoryObserver() {
    DisposableObserver<Story> observer = new DisposableObserver<Story>() {
        @Override
        public void onNext(Story value) {
            mStoryEmitter.onNext(value);
            dispose();
        }

        @Override
        public void onError(Throwable e) {

        }

        @Override
        public void onComplete() {

        }
    };
    return observer;
}
