How to get the size of an drawable image in android

Question

currently im working in drawable images in android, and now i want to get the size the drawable image in KB , how can i get it, any ideas are welcome.

Here im getting the default application icons and storing in an drawable array, is creating a new file for each icon for getting length is a good idea? Please suggest any better idea,thanks

Answer 1

Here's an idea. Convert the drawable image to a byte array... the array length is the size of the drawable image in bytes. Not sure if there is a better way...

I think u have to make it a file. But not sure whether it works

File root = new File(Environment.getExternalStorageDirectory()
                            + File.separator + "temp" + File.separator);
                    root.mkdirs();
                    File file= new File(root, "temp.png");

FileOutputStream fOut = new FileOutputStream(file);
                                                 bmp.compress(Bitmap.CompressFormat.PNG, 100, fOut);//bmp is bitmap of ur image
                         fOut.flush();
                         fOut.close();

Using file.length() should give you the file size.

I don't know if this will work in all situations but you can use this:

Drawable d;
long kbsize = ((BitmapDrawable)d).getBitmap().getByteCount() / 1024;
