What you will learn

  • Build lifecycle-aware coroutine and Flow pipelines.
  • Choose durable storage and validate remote data.
  • Verify denied, accessible, adaptive, and failure scenarios.

  1. ViewModel, structured coroutines, and Flow

    Create a screen state pipeline whose ownership, cancellation, and error behavior remain understandable during asynchronous updates.

    Start learning

  2. Room, DataStore, and durable data

    Choose storage by data shape and consistency needs, then preserve user records through transactions and schema evolution.

    Start learning

  3. Networking and repository boundaries

    Convert unreliable remote responses into validated local behavior without blocking the UI or hiding failures.

    Start learning

  4. Permissions and respectful platform integration

    Build optional camera and notification features around user intent, denial, and version-specific platform contracts.

    Start learning

  5. Testing and evidence-based debugging

    Build confidence through focused tests and isolate failures using reproducible evidence rather than timing guesses.

  6. Accessible and adaptive feature design

    Preserve the same reading task across window changes, assistive technologies, and non-touch input.
