Determine if the device is a smartphone or tablet? [duplicate]

Answer 1

Since tablet are in general bigger than smartphones and since a low res tablet may have the same number of pixels as a high res smartphone, one way to solve this is to calculate the physical SIZE (not resolution) of a device:

    DisplayMetrics metrics = new DisplayMetrics();
    getWindowManager().getDefaultDisplay().getMetrics(metrics);

    float yInches= metrics.heightPixels/metrics.ydpi;
    float xInches= metrics.widthPixels/metrics.xdpi;

   if (yInches> smallestTabletSize|| xInches > smallestTabletSize)
    {
                  //We are on a 
    }
