How to remove email icon from Android Studio emulation

Question

How do I get rid of the email icon on the bottom of the phone? It is on all of them and it shouldn\'t be there.

Answer 1

Go to activity_main.xml and delete this portion:

And then go to MainActivity.java and delete this portion

FloatingActionButton fab = (FloatingActionButton) findViewById(R.id.fab);
        fab.setOnClickListener(new View.OnClickListener() {
            @Override
            public void onClick(View view) {
                Snackbar.make(view, "Replace with your own action", Snackbar.LENGTH_LONG)
                        .setAction("Action", null).show();
            }
        });

That's it. You should now see that the icon disappeared.
