How to add multiple marks on MapView - over a hundred

I followed the Hello MapView tutorial on the developer site, and got everything working well. But now I need to expand upon that to add around 150 markers, and my current method crashes my app.

Reason: keyDispatchingTimedOut

My set up is as follows..

Four String arrays with the data for the map, all have (and always will) have the exact same number of indexes and fId[0] == fLatitude[0] == fLongitude[0] == fDetails[0], and so on:

    String[] fId;
    String[] fLatitude;
    String[] fLongitude;
    String[] fDetails;

As of now this is how I am plotting the points on the map. 开发者_C百科 This is obviously not the correct way because the map keeps crashing:

        List<Overlay> mapOverlays = mapView.getOverlays();
    Drawable drawable = this.getResources().getDrawable(R.drawable.androidmarker);
    FriendItemizedOverlay itemizedoverlay = new FriendItemizedOverlay(drawable, mapView.getContext());

    for(int i=0;i<aLatitude.length;i++){

        Double intLon = Double.parseDouble(aLongitude[i]);
        Double intLat = Double.parseDouble(aLatitude[i]);

        GeoPoint point = new GeoPoint((int)(intLat * 1E6), 
                (int)(intLon * 1E6));
        OverlayItem overlayitem = new OverlayItem(point, "Friend ", "Something");

        itemizedoverlay.addOverlay(overlayitem);
        mapOverlays.add(itemizedoverlay);

    }

Let me know in the comments if you need anymore info, thanks.

You are adding the same overlay 150 times to the map. Please only add it once.
