Android creating BitmapDescriptor exception
<p>I'm writing an application that works alot with google map and markers on it. My task is to create and display some amount of markers on google map. Markers have custom image and text in it. Data is loading from server and i need to display new amount of data every time user moves google map camera. So i'm using android-maps-utils:0.4.3 library for creating custom Bitmap (using IconGenerator) and then create BitmapDescriptor from it. Here is part of the code:</p>

<pre><code>  googleMap.clear()

        LayoutInflater layoutInflater = (LayoutInflater) getContext().getSystemService(Context.LAYOUT_INFLATER_SERVICE);

        IconGenerator clusterIconGenerator = new IconGenerator(getActivity());
        View clusterView = layoutInflater.inflate(R.layout.marker_cluster_view, null, false);
        clusterIconGenerator.setContentView(clusterView);
        clusterIconGenerator.setBackground(ContextCompat.getDrawable(getActivity(), R.drawable.mark_normal_grey));

        List&lt;Cluster&gt; clusters = result.getResult();  // server data

        for (Cluster cluster : clusters) {
            Bitmap bitmap = clusterIconGenerator.makeIcon(String.valueOf(cluster.getOffersCount()));

            Marker marker = googleMap.addMarker(new MarkerOptions()
                    .position(new LatLng(cluster.getLocation().getLatitude(), cluster.getLocation().getLongitude()))
                    .icon(BitmapDescriptorFactory.fromBitmap(bitmap))  // crash here
                    .anchor(0.5f, 0.5f));

            markerClusterMap.put(marker, cluster);
        }

<p>Everything is ok except application is crashes sometimes (not very often) with 2 different exceptions:</p>

<p>What can i do with this? I guess i'm using my memory to much to create BitmapDescriptors. It's nearly 20 BitmapDescriptos every 3 seconds if user moving camera too much. Should i cache it somehow? Thx a lot for your answers and time!</p>
