Thank you for considering me for the development of the Caller ID application for Android and iOS platforms with the specified features.
For the Comprehensive Call Identification and Anti-Spam function, I propose using a combination of technologies and services available on Android and iOS. We can use the APIs provided by the operating systems to identify incoming calls and verify them through an external API that queries the MySQL database. With this information, the application will display the caller's phone number, name, photo, and address if available in the database.
For the login and database access, we will use a secure connection using HTTPS for the server and user authentication with username and password. The information of the person who provided the phone number will be retrieved from the database to display their name, photo, and address on the call identification screen.
To save new numbers, the application will allow the user to add them through an intuitive interface that will communicate with the API and store them in the MySQL database.
Contact synchronization will be implemented so that whenever the application gets an internet connection, new numbers will be downloaded to the mobile device for viewing and dialing without an internet connection.
The relationship between the application and the database will be established through an API that will handle database queries and updates securely and efficiently.
