I have an existing simple app that saves data that the user enters, I am sendiing you the manual of the app to understand the function.
I would like to add:
1. Change the UI of one of the buttons /activity
2. Add a Printing button in that activity,
there will be an excel template that will be printed.
I dont have the latest Source code, but I have source code before some changes was made.
So I have not the latest source code available.
