Modern Android App Prototype Design

I need a polished, fully-interactive prototype for an Android mobile app. The aesthetic must lean toward a clean, modern style with consistent fonts, spacing, buttons and layouts that feel light but professional.

Core screens I want to see are:
• Welcome / Login
• Dashboard with clearly separated sections
• Product or Course listing view
• Individual Product / Course detail view

Each screen should be linked with smooth, clickable interactions so the flow feels natural during a client walk-through. Although the primary target is Android phones, designing with responsive constraints in mind—so layouts still read well on larger devices—will be appreciated.

I plan to present this prototype to stakeholders, so the visuals have to look production-ready: crisp components, intuitive navigation, and no placeholder clutter. You’re free to use Figma (preferred) or a comparable prototyping tool, but please share the working file plus an easily accessible prototype link at hand-off.

Acceptance criteria
1. All screens listed above delivered in Figma with tidy, named layers and reusable styles/components.
2. Interactive prototype link demonstrating end-to-end navigation without dead ends.
3. Visual consistency across typography, color, spacing and iconography.
4. Assets optimised for Android resolutions and guidelines.

If you have recent examples of modern Android app UI work, I’d love to review them alongside your proposal.
