Check out the thumbnail generation routines for media provider: http://developer.android.com/reference/android/media/ThumbnailUtils.html

Bitmap thumbBitmap = ThumbnailUtils.extractThumbnail(BitmapFactory.decodeFile(filePath), thumbWidth, thumbHeight);

Check out the thumbnail generation class inside Android itself - http://developer.android.com/reference/android/media/ThumbnailUtils.html

It's available since API level 8.

Once you have the bitmap, you can convert it to a thumbnail using createScaledBitmap (Bitmap src, int dstWidth, int dstHeight, boolean filter) or, for Android2.2 and up, using Bitmap extractThumbnail (Bitmap source, int width, int height).

I think you'll have to get the full image and either scale it, or decode it specifying inSampleSize>1 in BitmapFactory.Options.
