Hello Friends/developers, 

I am running into problems process this java code for ordering coffee, 
when i click on the my created button on my cell phone it blinks and does not go anywhere, thus I can't really see if I am doing things right or not, In android studio in preview i can at least see how it looks like but obviously i am unable to click on order button and see changes. 

Another issue in MainActivity.Java list I can't delete some text on the top like 
package com.example.android.justjava;


import android.os.Bundle;
