下拉前景服务冻结通知栏

Question

我正在开发一个Android应用程序，我正在启动一个无限期运行的后台服务，但运行得很好但是在做了一些研究之后，似乎我应该将它添加为前台服务，以便它具有被杀的可能性更小。即使应用程序关闭或被杀，我也希望此服务继续在后台运行。将前台服务添加到我的服务类之后，我注意到当你拉下通知栏时，手机会冻结并且屏幕会在显示备份之前擦除空白几秒钟。通知栏在加载后按计划工作，但它占用的时间太长。我对服务很新，但我开始更好地掌握它们，所以任何帮助都非常感谢。一直在运行Anodrid 5.1.1的One Plus Two手机上进行测试。这是我的应用设置：

MainActivity.java

@Override
public void onClick(View v) {
    switch (v.getId()) {
        Intent serviceIntent = new Intent(this, MileageService.class);
    serviceIntent.setAction("start");
    startService(serviceIntent);

    Intent i = new Intent(getApplicationContext(), MapsActivity.class);
    startActivity(i);
    }
}

MileageService.java

@Override
public void onCreate() {
    super.onCreate();
}

@Override
public int onStartCommand(Intent intent, int flags, int startId) {

    //Everything under here before the final return START_STICKY 
    //was newly added and is the source of the new issues

    if (intent.getAction().equals("start")) {
        if(stringNames.size() == 0) {
            subscribeToLocationUpdates();

            Intent stopIntent = new Intent(this, MileageService.class);
            stopIntent.setAction("stop");
            PendingIntent pStopIntent = PendingIntent.getService(this, 0, stopIntent, 0);

            Bitmap icon = BitmapFactory.decodeResource(getResources(), R.mipmap.icon_name);
            Notification notification = new NotificationCompat.Builder(this)
                    .setContentTitle("Mileage Service")
                    .setTicker("Mileage Service")
                    .setContentText("Mileage service is running")
                    .setSmallIcon(R.drawable.android_logo)
                    .setLargeIcon(icon)
                    .setOngoing(true)
                    .addAction(R.drawable.ic_media_pause, "Stop", pStopIntent).build();
            startForeground(101, notification);
        }else{
            return START_STICKY;
        }
    } else if (intent.getAction().equals("stop")) {
        stopForeground(true);
        stopSelf();
    }
    return START_STICKY;
}

public void onLocationChanged(final Location loc) {
    Log.i("***********", "Location changed");
    //I also do code here that updates global variables 
    //that get put into an intent to be sent back to app in further 
    //activities but not showing it as it works fine before adding 
    //notification foreground code

    intent.putExtra("names", stringNames);
    LocalBroadcastManager.getInstance(getApplicationContext()).sendBroadcast(intent);        
}
