Android menu set icon through java

Question

I trying to set icon on menu item through java code

m1.setIcon(getResources().getDrawable(R.drawable.play));

on this line my app is crashing check is error

Answer 1

The MenuItem is not initialized so it causes a null object reference. you should inflate the MenuItem to be initialized in order to.setIcon(...);

Please share more code, to take a detailed solution.
