Prevent services of Android app from being killed using Intent.ACTION_TIME_TICK

// register intent time tick receiver which ticks every minute
registerReceiver(timeTickReceiver, new IntentFilter(Intent.ACTION_TIME_TICK));

    /**
     * restart service every minute if it's killed
     */
    private BroadcastReceiver timeTickReceiver = new BroadcastReceiver() {
        @Override
        public void onReceive(Context context, Intent intent) {
            try {
                boolean isServiceRunning = false;

                if (intent.getAction().equals(Intent.ACTION_TIME_TICK)) {

                    ActivityManager manager = (ActivityManager) getApplicationContext().getSystemService(Context.ACTIVITY_SERVICE);

                    if (manager != null) {
                        for (ActivityManager.RunningServiceInfo service : manager.getRunningServices(Integer.MAX_VALUE)) {
                            if ("net.pupli.monitoring.MyMqttService".equals(service.service.getClassName())) {
                                isServiceRunning = true;
                            }
                        }
                    }

                    if (!isServiceRunning) {
                        Intent i = new Intent(context, MyMqttService.class);
                        context.startService(i);
                    }
                }
            } catch (Exception ex) {
                ex.printStackTrace();
