Как сделать,чтобы при блокировке телефона mediaplayer не переставал работать?

Здравствуйте, у меня есть fragment, где воспроизводится радио, при нажатии на кнопку. Если экран отключается, то радио получается тоже, какие варианты есть?
код фрагмента

public class AsaFragment extends Fragment {
    private static final String LOG_TAG = "myLog";
    private List<Item> itemList = new ArrayList<>();
    private RecyclerView recyclerView;
    private ToggleButton playPause;
    private ToggleButton stopButton;
