Answer 1

Execute the following code:

float scale = getApplicationContext().getResources().getDisplayMetrics().density;

and check the value of scale:

• 0.75 means low density
• 1.0 means standard (medium) density
• 1.5 means high (large) density
• 2.0 means extra high density
• 3.0 means extra extra high density
• 4.0 means extra extra extra high density

See the documentation for more info.
