Displaying any sized images on Android

ImageView imageView=new ImageView(this);
imageView.setScaleType(ImageView.ScaleType.CENTER_INSIDE);
imageView.setAdjustViewBounds(true);
FileInputStream fis=new FileInputStream(file);
BitmapFactory.Options options=new BitmapFactory.Options();
options.inSampleSize=2; //try to decrease decoded image
options.inPurgeable=true; //if necessary purge pixels into disk
options.inScaled=true; //scale down image to actual device density
Bitmap bm=BitmapFactory.decodeStream(is, null, options);
imageView.setImageBitmap(bm);
fis.close();
