We just saw how adding a Button generates the XML for us. Now let's write the XML by hand. Start simple by adding a Button element. Copy and paste the TextView element and just change 'TextView' to 'Button'.

Write:

 Button
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        />

Always check your spelling ;) You wrote a small 'b' instead of a 'B'. I hope that was the problem

with a "smaller symbole" in front of Button. It somehow won't let me write it properly

No problem :)

If you do what they tell you you should, and you are absolutley certain that you did it right, it is most likely a spelling mistake on your side ;)
