Details of app design:

Start page

• Textview 1: display the title
• Button 1:takes you to the Register page
• Button 2:takes you to the login page

this is the main start up page of my app and all it does is tell the user what kind of app this is and allow the user to navigate to the register page or the login page using the buttons.

Register page

• text view 1 :displayes the title

this is the regsiter page that allow the user to make an acount using a user name and an password using the input widgets with some user error handling added in and it make a new object in my firebase databse for the user and with all the object it will need and once you click the regsiter button it takes you to the login page to login there.

• Textview 1: tells user what to do on the page
• Input 1: lets user type username

Reflective statement

In the making of my budget app I got a more indepth view into some of the knowledge like VOLLEY as i was able to know about the use of POST and PATCH using volley to write to the database and also to upadate the databse and i feel like a got a better grasp on the passing of data between fragments using arguments and bundles after making this app and during the course of the project i did use generative AI to help with this project which i will have the links for the chats in a file called generativeAI and the way i used this was to ask about version of thing i didnt know about like the POST and PATCH for VOLLEY and also error code that i got or things that heppened when i was running the debugger like jumping methods or lines of code ect but i also had problems with this as the code generated sometimes woulnt add a varaible so the code wouldnt work as inteded and also some times i was only give the code for one fragment so it didnt know if the bundle was really being passed to this fragment so it just assumed that something was wrong with the IDE or my internet permissions ect. something succeful with the project would be able to fully read and write to the firebase database using volley since i hade more then one GET, POST and PATCH so im glad that they all work since some times i had to use a get to post something like get a key from a jsonobject. what could of gone better is more user error as right now two user can be called the same thing with the same password
