How to start making an inventory app?

Question

Android

There is an idea to create a small ios / android application for working with a database that works according to the following scheme: A
smartphone scans a barcode, accesses the mysql server with this data, and something like a "product card" appears on the screen. The application is needed to organize an inventory and quickly search for detailed characteristics of a product (more precisely, server hardware).
Tell me where to start besides smart books "ios-dev for nubbies"? How difficult would it be to create something like this without experience?
PS: maybe there is something similar already? IOS-mysql client with barcode search

Answer 1

Make an exact technical specification for the project (a list of functions, draw buttons on what should be loaded and from where, where requests should be sent) and start doing. If you have no experience in development, first get your hands on simple applications ( hello world ) and gradually complicate them.

Answer 2

Do not connect to the database from the application directly. Write an api, upload it to the server and use the application to access the api.

no experience in mobile development at all?
Let's assume you already know Java at the OCA level.
if so, then for half a year or a year (depending on the intensity) of games with hello waters for different technologies (simple application, design / architecture of a simple multi-threaded application, networking, simple data exchange with the server, structuring a complex project, connecting external libraries , ...) - you will master all the technologies you need to build such an application. If you persevere only in this, then in a couple of months you can do it. (if you have good development experience in general, but since you ask questions of the kind you ask, then, I suppose, you don’t have such experience yet ....)
But then it will be easier. A couple of weeks, if you do not use any frameworks (except for external projects like "scanning barcodes") and so on.
