How to Compare Two ImageViews?

I want to check if two imageViews match or not , by getting their background from the Drawable .

i did use this way :

     if (imgView1.getBackground().getConstantState()
    .equals(ContextCompat.getDrawable(getApplicationContext(),R.drawable.myImage)
    .getConstantState())
     &&
    imgView2.getBackground().getConstantState()
.equals(ContextCompat.getDrawable(getApplicationContext(),R.drawable.myImage)
    .getConstantState()))
        {


        // do something 
        }

it works great on API 23 and API 24 , but not working with API 21 and API 26 ? is there another way to make it work for all android versions?

  Bitmap bitmap = ((BitmapDrawable)imgView1.getDrawable()).getBitmap();
    Bitmap bitmap2 = ((BitmapDrawable)imgView2.getDrawable()).getBitmap();
