The 750,000 bytes are the size of the *compressed* JPEG. A Bitmap instance holds the *raw* color data, not the compressed data.
E.g. if the raw color data has format ARGB_8888, then each pixel uses 4 bytes: 5MPixel images will use 20MBytes of memory. If the raw color data has the format RGB_565, then each pixes uses 2 bytes: 5MPixel images will use 10MBytes of memory. This is what you see. To load the image for viewing, you don't need more than the screen- resolution. Use the inSampleSize of the BitmapFractory.Options; set it to a number larger than 1 (preferably a power of 2).
