right now I am developing an application and it has some set of images in a server machine. Is there anyway to update the drawables folder at application startup, so these images will have some ID in the R file (I am sliding the drawables in an imageview, image changes with duration in an ImageView). I prefer to store images in a central machine so that all tablets connected to the database will pick the images from a central machine at application startup or check it periodically. Otherwise every tablet needs to get reinstalled everytime I add some advertisement image to the drawables folder.
Thanks in advance
No you cant update drawable folders from code. You can use web service to pull the image and use it as image source of the image view.
Here is an example How to load an ImageView by URL in Android?
