How to make "drawable" files accessible through the code

public static Bitmap loadBitmap(Context context, String filename){
        AssetManager assets = context.getResources().getAssets();
        InputStream buf = null;
        try {
            buf = new BufferedInputStream((assets.open("drawable/black_circle.png")));
        } catch (IOException e) {
            e.printStackTrace();
        }
        Bitmap bitmap = BitmapFactory.decodeStream(buf);
        return bitmap;
    }

when I use the code above the system gives the following error

09-27 12:33:44.470: W/System.err(18554): java.io.FileNotFoundException: drawable/black_circle.png
09-27 12:33:44.470: W/System.err(18554):    at android.content.res.AssetManager.openAsset(Native Method)
09-27 12:33:44.470: W/System.err(18554):    at android.content.res.AssetManager.open(AssetManager.java:315)
09-27 12:33:44.470: W/System.err(18554):    at android.content.res.AssetManager.open(AssetManager.java:289)

I'm running the code on a Samsung Galaxy, through Eclipse. How to make this work?

I need to change the file name dynamically.

Try this way :

int image_id = getResources().getIdentifier("imagename", "drawable", getPackageName());

image.setBackgroundResource(image_id);

You can try :

InputStream is = (InputStream) context.getResources().openRawResource(R.drawable.black_circle);

Try this.

Bitmap bitmap = BitmapFactory.decodeResource(getResources(), R.drawable.addto);

if you want to create bitmap from the drawable image then you can use this.
