I have an application where I need to draw many Graphics on a map, and detect clicks on them. To make this process efficient, I maintain a bi-directional mapping of graphic IDs and object IDs, so basically given a graphic ID, I can determine which of my objects is represented by that graphic. And given one of my objects, I can tell which graphic on the map is representing it. This takes some initial setup, when the Graphics are first drawn on the map. Unfortunately, you can't obtain the id of a Graphics object with something like this:     Graphic myGraphic = new Graphic()     graphicLayer.addGraphic(myGraphic)     graphic.getId() (or graphic.getUid()) the methods to get ID and UID both return -1 at this point, which I assume has to do with the immutability of Graphics objects. So what I end up having to do is adding attributes to each graphic that contain the object Id, and then do this:     int[] graphicIds = graphicLayer.getGraphicIds()     for (int i = 0; i < graphicIds.length; i++){         Graphic myGraphic = graphicsLayer.getGraphic(graphicIds)         int objectId = myGraphic.getAttributes().get("MY_OBJECT_ID_KEY")         //create mapping of  graphicId <--> objectId     } The issue with this is that the graphicsLayer.getGraphic(int id) method takes a long time, usually from 0.1 - 0.15 seconds. Once we get up to only thirty icons that we need to show on the map, the user will be waiting over three seconds, where the application is completely frozen, since this must be on the UI thread. Is there a way, if you have the graphic id, to get the attributes for a graphic without getting the graphic itself? I'm thinking that might speed up this process. Is there another approach I could take on this problem? ... View more

I've been working on a map that places PictureMarkerSymbols with custom drawables, and I've noticed that the PictureMarkerSymbols are blurry when displayed on the map. I've tried the following: drawables in drawable-mdpi, drawable-hdpi, drawable-xhdpi, etc. and the PictureMarkerSymbol(Context, Drawable) constructor. Images are not sharp at all (though appropriately sized) drawables in drawable-mdpi, drawable-hdpi, drawable-xhdpi, etc. and the PictureMarkerSymbol(Drawable) constructor. Images are somewhat sharp and way too big drawables in drawable-nodpi and PictureMarkerSymbol(Drawable) constructor. I just used the smallest Drawable I had, which was the mdpi one. Drawables were appropriately sized but still blurry drawable in the drawable (no qualifiers) folder and the PictureMarkerSymbol(Drawable) constructor. Huge and blurry The my location (blue dot) icon is very crisp. How do you achieve this. Note: after more testing, I've noticed the blurriness is more pronounced with a LayerDrawable. Could this be the source of my issue? ... View more
