The code is as follows1 bitmapfactory.options Options = new Bitmapfactory.options ();2 options.insamplesize = 2;3 Bitmap img = bitmapfactory.decodefile ("/sdcard/1.png", options);
This code is read 1.png thumbnail, length, width is only 1/2 of the original picture. The size of the picture is reduced and the memory footprint is naturally smaller. The disadvantage of this is that the picture quality is bad, the larger the value of the insamplesize,
