using Java in Android ,how can you automatically crop images with different sizes?

// From drawable
Bitmap src= BitmapFactory.decodeResource(context.getResources(), R.drawable.image);
// From URL
Bitmap src = null;
try {
    String URL = "http://www.example.com/image.jpg";
    InputStream in = new java.net.URL(URL).openStream();
    src = BitmapFactory.decodeStream(in);
} catch (Exception e) {
    e.printStackTrace();
}
int width = src.getWidth();
int height = src.getHeight();
int crop = (width - height) / 2;
Bitmap cropImg = Bitmap.createBitmap(src, crop, 0, height, height);
ImageView.setImageBitmap(cropImg);
