Edit

I can't share the whole source code, but I am using two fragments. One fragment contains map and another contains a listview of images. I call a webservice every 10 seconds and update listview images and bound map with locations I get in response of web service.

if ( map!=null) {
        if (activity.ambDetailList.size() > 0) {
            int i;
            double dist, currentLat = 0.0, currentLng = 0.0;
            ambOnlineList.clear();
            String ETA, SPEED;

            Marker marker;
            for (i = 0; i < activity.ambDetailList.size(); i++) {
                ambulanceDetail = activity.ambDetailList.get(i);
                dist = Math.sqrt(Math.pow(ambulanceDetail.getCurrentLat() - ambulanceDetail.getDestLat(), 2) + Math.pow(ambulanceDetail.getCurrentLng() - ambulanceDetail.getDestLng(), 2));
                double minute = ((dist * 100) / (ambulanceDetail.getSpeed() * 60 / 1000));
                double speed = ambulanceDetail.getSpeed() * 60 * 60 / 1000;
                Log.i("Minute", "----->>>>" + minute);
                if (speed >= 0.00 && speed <= 1.00) {
                    ETA = activity.getResources().getString(R.string.text_infinity);
                    SPEED = activity.getResources().getString(R.string.text_infinity);
                } else if (minute > 60) {
                    double hour = minute / 60;
                    int roundHour = (int) (minute / 60);
                    int min = (int) ((hour - roundHour) * 60);
                    ETA = roundHour + " hour " + min + " min";
                    SPEED = (int) (ambulanceDetail.getSpeed() * 60 * 60 / 1000) + " km/h ";
                } else {
                    ETA = (int) (minute) + " min ";
                    SPEED = (int) (ambulanceDetail.getSpeed() * 60 * 60 / 1000) + " km/h ";
                }

                ambulanceDetail.setEta(ETA);
                ambulanceDetail.setDisplayETA(ETA);
                ambulanceDetail.setDisplaySpeed(SPEED);

                if (markerList.get(ambulanceDetail.getAmbulanceId()) == null) {
                    MarkerOptions markerOptions = createMarker(ambulanceDetail);
                    marker = map.addMarker(markerOptions);

Anyway, you can restart application (or if that didn't helps - reboot device) before map starts blinking, for example after 15 hours of work (or e.g. 500 calls of web service):

...
Intent restartIntent = getBaseContext().getPackageManager()
         .getLaunchIntentForPackage( getBaseContext().getPackageName() );
restartIntent.addFlags(Intent.FLAG_ACTIVITY_CLEAR_TOP);
startActivity(restartIntent);
...
