I am the beginner.This is my first project.

I want to know things to improve my project and make my project much more better.

CAN someone comment it?

Hi

It's unfinished but you have got a lot done and used some good technique such as implementing Arrangements, something that a lot of beginners miss!

Your buttons are way too small yet they need not be. I don't like the animated pointing finger but that's just my personal preference :)

Set the options for App/Screen1:

• Orientation Portrait
  
• Sizing Responsive
  
• Scrollable
  

In general, be specific about what you want to see, don't leave options as "default".

Screen1 Blocks 

• Since you allow NUM1 to NUM4 to be either numerals or Characters, you need to test what type they are before applying a sum.
  
• Code is not safeguarding against the User input of illegitimate Characters/Numbers.
  

Screen2 Blocks

Cannot do this, it results in a memory leak:

Do this instead:

User will be taken back to the Calling Screen (in this case, Screen1)

Screen2 ignores User hitting the Device Back Button.......
