Android QR Code Reader app -- 2

Hello

I need an Android QR code reader application. The app must be written in Kotlin language.

It will scan all types of QR codes and barcodes including QR, Data Matrix, Aztec, UPC, EAN, Code 3, etc.

All the screen layouts and the workflow will be provided to design the UI for material design.

There will be 4 tabs; Scan, Create, History, and Settings.

At first open there will be an onboarding screen including 3-4 pages with image, title, and subtitle to introduce the app. At the last screen, we will request camera permission to scan QR codes and barcodes.

A purchase screen will show up after onboarding completed and each app opens if not purchased yet. We will sell a one-time product or an auto-renewable subscription. So the app must comply with 2 types of in-app purchases. If we sell a time product the app will be Premium all time. But if we sell auto-renewable subscription the app must follow the subscription renews, cancels, and refunds. If the subscription failed or canceled over time the app must return to Free mode which has some restrictions and ads.

Some texts, settings, and product types will be fetched from the API.

Scan Tab: A full camera view on the screen. Flash on/off button. Batch scan button, Image select button to scan code from the image gallery.

A frame will be over camera view to align the code and a laser animation going up/down inside the frame.

At the normal scan, the detail screen will be showed after the code scanned but if the user selects batch scan mode it will add the scanned codes to an array, and when the user finishes it will show up all scanned codes. Users will be able to remove some or continue to save all to the database.

History Tab: In this screen, all the scanned codes will be shown including the user-created folders. When users scan a code it will be saved to the default folder which shows in the History tab below folders, but then users should be able to move them into created folders. Also, users can export CSV files from selected codes.

Create Tab: In this screen, the user-created codes will be shown. Also, there will be a button to create a new one. When the user touches a code the detail screen will be shown with code detail including created code or barcode image. There are 2 types of codes; QR and Barcodes. Users can switch between types to select Code types such as web address, plain text, contact, email address, SMS, code 128, ean-13, ean-8, ISBN, etc. Each QR type has different inputs and they will be provided by me. For example an URL input for web links, single input for plain text, etc.

Setting Tab: In the setting tab there will be a few settings for the app. At top of the app name and if not purchased, purchase button. Scan settings; beep, vibrate, open link, batch scan, laser animation, repeated scans. General settings; date format, default browser, beep sound. And a few buttons to contact us, share app, rate app, privacy policy, and terms of use links.

Ads: There will a banner on each tab and we will show interstitial ads on specific actions. Of course if not purchased. Also, some features will be disabled for Free users.

Each code has its structure. I will provide documents and codes on how to detect them. The iOS version was written by me so I can provide all required structures, resources, and codes.

The app will be ready for localization but we will add other languages on the other versions.

The API will provide only a few setting values. Not much playing with web APIs.

As I mentioned before the app must be written in Kotlin language, not Java.

I will provide all screens, resources, fonts, sounds, and codes as you need. If you need I can share some parts of the iOS version written in Swift.

Used SDKs; KochavaTracker, JNCryptor, Firebase, Facebook, Admob,

The iOS version for the reference; [login to view URL]
