Answer 1

int screenSize = getResources().getConfiguration().screenLayout &
        Configuration.SCREENLAYOUT_SIZE_MASK;

switch(screenSize) {
    case Configuration.SCREENLAYOUT_SIZE_LARGE:
        Toast.makeText(this, "Large screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_NORMAL:
        Toast.makeText(this, "Normal screen",Toast.LENGTH_LONG).show();
        break;
    case Configuration.SCREENLAYOUT_SIZE_SMALL:
        Toast.makeText(this, "Small screen",Toast.LENGTH_LONG).show();
        break;
    default:
        Toast.makeText(this, "Screen size is neither large, normal or small" , Toast.LENGTH_LONG).show();
}
