Align an icon with the Toolbar icon - Android Material Design

Question

In the new Material Design (using AppCompat), I am trying to align some action icons with the drawer icon of the new toolbar. Something like:

Answer 1

The problem is that I can't perfectly align it, because after that left padding of 16px, the icons should start, but the icon itself has also some "padding" (icon from material github)

Yes, the icon must have some padding and it varies depending on which screen resolution the icon will be displayed. The padding for different screen density:
mdpi        4px * 1.0 = 4px
hdpi         4px * 1.5 = 6px
xhdpi       4px * 2.0 = 8px
xxhdpi     4px * 3.0 = 12px
xxxhdpi   4px * 4.0 = 16px
This is the padding included in the icon drawable and you shouldn't remove it.
