Android app design guidelines

Question

I have read the Android Developers documentation and more specifically this one: http://developer.android.com/design/style/metrics-grids.html

So now my size for design must be 360dp * hdpi - hdpi @ 360.00dp = 540.00px width and custom height (depends on scrollable or unscrollable content). Did I understand right or?

Answer 1

You cannot be sure in any size of device, or even proportions. Both phones and tablets are VERY different: http://developer.android.com/guide/practices/screens_support.html#range You cannot "hardcode" something in design.
