Study Notes

Cloud Storage

Cloud storage integrates into mobile apps for enhanced functionality and scalability.
It enables real-time data sharing, secure backups, and scales to handle large data volumes.
Real-time data sharing allows users to share and access information instantly.
Data analysis with cloud-based analytics reveals trends and user preferences.
Personalized experiences based on user interests and needs are possible.

Building an Android App with Firebase and Jetpack Compose

This approach demonstrates how to build Android apps using Firebase and Jetpack Compose.
The app architecture uses a Model-View-ViewModel (MVVM) pattern.
The Model manages app data, while the View handles user interface elements, and the ViewModel handles business logic.

Firebase Authentication

Firebase Authentication provides a robust backend for user authentication.
Authentication is supported by various methods like passwords, phone numbers, Google, Facebook, and Twitter integration.
This secure and seamless user experience is offered through the framework.

Firebase Project and Firestore

Firebase Project acts as a container for all apps and resources.
Multiple iOS and Android app versions can be supported within the same project.
Firebase Project and Firestore enable shared resources and services like hosting, authentication, real-time database, Cloud Firestore, Cloud Storage, and Cloud Functions.
Firestore is a scalable database with real-time sync.
It ensures offline access and facilitates responsive app functionality.

Halal Food App with Cloud Storage

The app shares health tips and product benefits, offering real-time data sharing.
Cloud-based analytics reveal trends and user preferences.
Personalized experiences using recommendations tailor to user interests and needs.
This app demonstrates cloud storage's transformative potential for creating engaging and functional apps.

Practical Example (Make It So)

The app is a to-do list demonstrating features such as adding, editing tasks, assigning priorities and due dates.
It integrates Firebase and Jetpack Compose.
The app shows a practical example of using cloud storage for a to-do list application. Data flow from input to storage is demonstrated.

Lab Test

The lab test includes an easy question (4 marks) and a difficult question (6 marks), due on January 11, 2024.
The test requires restricted use of resources including UKMfolio, Google Translate, and Android Developer documentation.
A lab notebook is required for notes and documentation.
