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:

<android.support.design.widget.FloatingActionButton android:id="@+id/fab"         android:layout_width="wrap_content" android:layout_height="wrap_content"         android:layout_gravity="bottom|end" android:layout_margin="@dimen/fab_margin"         android:src="@android:drawable/ic_dialog_email" /> 

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.
