    The BitmapFactory class creates bitmap objects from various sources that can be files, streams, or byte-arrays . Its use is suggested when uploading images from the sdcard or disk.

    An example, create a bitmap object from an image stored on the sdcard and which we add to an ImageView:

    ImageView imageView = (ImageView) findViewById(R.id.mi_imagen);
//Convierte a mapa de bits
Bitmap bitMap = BitmapFactory.decodeFile("/sdcard/mi_imagen.png");
//Carga imagen en imageView obtenida a partir de un recurso.
imageView.setImageBitmap(bitMap);
