android - 使用android服务时出现内存不足错误

Question

我有一个 android 应用程序，它通过 Volley 从服务器获取一些帖子我想在将新帖子添加到服务器时播放音乐对于这种情况我将旧计数存储在共享的 prefrence 变量中，我每 7 次从服务器获取列表大小第二和比较老伯爵如果他们不同，音乐就会播放

每件事都运行良好，但几个小时后我得到这个内存不足错误：

STACK_TRACE=java.lang.OutOfMemoryError: thread creation failed

    at java.lang.Thread.start(Thread.java:1050)

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执行此操作，我将不胜感激
