How to change Toolbar Navigation and Overflow Menu icons (appcompat v7)?

Question

I am having a hard time with v7 Toolbar. What was once a simple task for ActionBar, now seems overly complex. No matter what style I set, I cannot change either

Answer 1

In order to show the icon, use getSupportActionBar().setIcon(R.xxx.xxx)

In my case the code is:-

getSupportActionBar().setIcon (R.mipmap.ic_launcher);
