Question

我有一个Android应用程序，该服务器通过Volley从服务器获取一些帖子我想在这种情况下每当有新帖子添加到服务器时都播放音乐，我将旧计数存储在共享的prefrence变量中，每隔7秒从服务器获取列表大小，然后与旧计数进行比较如果它们不同，音乐会播放

一切正常，但是几个小时后，我得到了内存不足的错误：

STACK_TRACE=java.lang.OutOfMemoryError: thread creation failed

这是我的互联网服务代码：

public class InternetService7 extends Service {
    StringRequest request;
    public int notifNumber;
    public int notifNumberOriginal;
    Context context1;

    Context c2;

    SharedPreferences shp;

    int number = 0;
    int preNumber = 0;

    @Nullable
    @Override
    public IBinder onBind(Intent intent) {
        return null;
    }

    @Override
    public int onStartCommand(Intent intent, int flags, int startId) {
        context1 = this;

        shp = PreferenceManager.getDefaultSharedPreferences(getApplicationContext());
        SharedPreferences.Editor shpE = shp.edit();

        if (!shp.contains("countNumber")) {
            shpE.putInt("countNumber", 10);
            shpE.apply();
        } else {

        }
        final Handler handler = new Handler();
        handler.postDelayed(new Runnable() {
            @Override
            public void run() {
                try {
                    newCount(context1);
                } catch (Exception e) {

                }
                handler.postDelayed(this, 7000);
            }

        }, 7000);
        return START_STICKY;
    }

    private void newCount(final Context context) {
        RequestQueue queue = Volley.newRequestQueue(context);

        String url_notf_number = ..

        StringRequest stringRequest = new StringRequest(Request.Method.GET, url_notf_number, 
                new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        String r = response.substring(0, 14);
                        String number = r.replaceAll("\\D+", "");

                        notifNumber = Integer.parseInt(number);
                        notifNumberOriginal = notifNumber;
                        c2 = context;
                        context1 = context;
                        subCount1();
                    }
                }, new Response.ErrorListener() {
            @Override
            public void onErrorResponse(VolleyError error) {

            }
        });
        stringRequest.setShouldCache(false);
        queue.add(stringRequest);
    }

    private void subCount1() {
        try {
            int number1 = (shp.getInt("lastNumber", 0));

            notifNumber = notifNumber - number1;

            if ((notifNumber != preNumber) && notifNumber > 0) {
                preNumber = notifNumber;

                boolean b = false;

                MediaPlayer ourSong = MediaPlayer.create(context1, R.raw.iphone);
                ourSong.start();
                try {
                    MainActivity.setMyy("reload");
                } catch (Exception e) {
                }
            } else {
            }
        } catch (OutOfMemoryError error) {
        } catch (Exception e) {
    }
}

我不知道我是否正确地完成了操作，我将不胜感激
