How to detect a tablet device in Android?

Question

I am trying to port my application developed for smartphones to the tablets with minor modifications. Is there an API in Android to detect if the device is tablet?

Answer 1

place this method in onResume() and can check.

public double tabletSize() {

     double size = 0;
        try {

            // Compute screen size

            DisplayMetrics dm = context.getResources().getDisplayMetrics();

            float screenWidth  = dm.widthPixels / dm.xdpi;

            float screenHeight = dm.heightPixels / dm.ydpi;

            size = Math.sqrt(Math.pow(screenWidth, 2) +

                                 Math.pow(screenHeight, 2));

        } catch(Throwable t) {

        }

        return size;

    }

generally tablets starts after 6 inch size.
