    TextView drawerName = (TextView) navigationView.getHeaderView(0).findViewById(R.id.navDrawerName);
    TextView drawerEmail = (TextView) navigationView.getHeaderView(0).findViewById(R.id.navDrawerEmail);
    CircleImageView  drawerAvatar = (CircleImageView) navigationView.getHeaderView(0).findViewById(R.id.avatar);

It looks like that you haven't set the View of Activity by setting contentView as setContentView. Furthermore, please also check that setContentView layout also have the textview you are fetching.

hope this helps.
