Android: Get thumbnail of image on SD card, given Uri of original image

Question

So i\'ve got a Uri of an image the user chooses out of images off his SD card. And i\'d like to display a thumbnail of that image, because obviously, the image could be huge

If you like HQ thumbnails, so use [RapidDecoder][1] library. It is simple as follow:

import rapid.decoder.BitmapDecoder;
...
Bitmap bitmap = BitmapDecoder.from(getResources(), R.drawable.image)
                             .scale(width, height)
                             .useBuiltInDecoder(true)
                             .decode();

Don't forget to use builtin decoder if you want to scale down less than 50% and a HQ result. I tested it in API Level 8 :)
