Code to find the Device is Tablet or Small Device,Android

public

// considered a Tablet

Configuration.
SCREENLAYOUT_SIZE_LARGE);




// If XLarge, checks if the Generalized Density is at least MDPI

// (160dpi)

DisplayMetrics metrics =
new DisplayMetrics();

Activity activity = (Activity) activityContext;

activity.getWindowManager().getDefaultDisplay().getMetrics(metrics);
