This is not Java code, it's JavaScript. But the formula is what you're looking for: http://dpoisn.com/demos/aspectratio.php Check the code on that page. — durbnpoisn, Feb 08 '16 at 17:27

you can resize your bitmap using this.

Bitmap yourBitmap;
Bitmap resized = Bitmap.createScaledBitmap(yourBitmap, newWidth, newHeight, true);

or:

resized = Bitmap.createScaledBitmap(yourBitmap,(int)(yourBitmap.getWidth()*0.8), (int)(yourBitmap.getHeight()*0.8), true);
