Adding a bitmap to the drawable resources

Question

How can I add a Bitmap taken from the web (in the app i mean!) to the drawable resources? So i can access the Bitmap using R.drawable.bitmapName...

just move it into the drawable folder and eclipse should automatically generate the coresponding class entries in R.drawable...... — Erhard Dinhobl, Dec 29 '10 at 15:12
I want to do it programmatically! The app starts and download the image from the web. I've done thiss step, but now how can i save it to R.drawable? — Abramodj, Dec 29 '10 at 15:13

You can't modify that folder once your app is installed. In that case, you must copy the bitmap to a file and access it from there. Take a look at this other question:

I just wanted the bitmap to be in R.drawable so i could get its id as an int. Is there another way to get the id? – Abramodj Dec 29 '10 at 15:14

No, there's no way to do so "programmatically". – Cristian Dec 29 '10 at 15:16

The resources are compiled at the apk building time, so you cannot change it in runtime. If you want to have some identifier you can consider creating a shared preference where you can put in relation the downloaded image file with some id. But it will take some effort from you to implement the functionality.
