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.
