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(); 
}
