Answer 1

Answer is very simple no need of XML code it's a matter of 3 lines of java code in MainActivity,

import this line inside MainActivity.java

import android.support.v7.app.ActionBar;

inside Create Method

 ActionBar actionBar = getSupportActionBar();
 actionBar.setDisplayShowHomeEnabled(true);
 actionBar.setIcon(R.mipmap.icon_launcher);
