OpenClaw Android UI Style Guide

Scope: all native Android UI in apps/android (Jetpack Compose). Goal: one coherent visual system across onboarding, settings, and future screens.

1. Design Direction

• Clean, quiet surfaces.
• Strong readability first.
• One clear primary action per screen state.
• Progressive disclosure for advanced controls.
• Deterministic flows: validate early, fail clearly.

2. Style Baseline

The onboarding flow defines the current visual baseline. New screens should match that language unless there is a strong product reason not to.

Baseline traits:

• Light neutral background with subtle depth.
• Clear blue accent for active/primary states.
• Strong border hierarchy for structure.
• Medium/semibold typography (no thin text).
• Divider-and-spacing layout over heavy card nesting.

3. Core Tokens

Use these as shared design tokens for new Compose UI.

• Background gradient: #FFFFFF, #F7F8FA, #EFF1F5
• Surface: #F6F7FA
• Border: #E5E7EC
• Border strong: #D6DAE2
• Text primary: #17181C
• Text secondary: #4D5563
• Text tertiary: #8A92A2
• Accent primary: #1D5DD8
• Accent soft: #ECF3FF
• Success: #2F8C5A
• Warning: #C8841A

Rule: do not introduce random per-screen colors when an existing token fits.

4. Typography

Primary type family: Manrope (400/500/600/700).

Recommended scale:

• Display: 34sp / 40sp, bold
• Section title: 24sp / 30sp, semibold
• Headline/action: 16sp / 22sp, semibold
• Body: 15sp / 22sp, medium
• Callout/helper: 14sp / 20sp, medium
• Caption 1: 12sp / 16sp, medium
• Caption 2: 11sp / 14sp, medium

Use monospace only for commands, setup codes, endpoint-like values. Hard rule: avoid ultra-thin weights on light backgrounds.

5. Layout And Spacing

• Respect safe drawing insets.
• Keep content hierarchy mostly via spacing + dividers.
• Prefer vertical rhythm from 8/10/12/14/20dp.
• Use pinned bottom actions for multi-step or high-importance flows.
• Avoid unnecessary container nesting.

6. Buttons And Actions

• Primary action: filled accent button, visually dominant.
• Secondary action: lower emphasis (outlined/text/surface button).
• Icon-only buttons must remain legible and >=44dp target.
• Back buttons in action rows use rounded-square shape, not circular by default.

7. Inputs And Forms

• Always show explicit label or clear context title.
• Keep helper copy short and actionable.
• Validate before advancing steps.
• Prefer immediate inline errors over hidden failure states.
• Keep optional advanced fields explicit (Manual, Advanced, etc.).

8. Progress And Multi-Step Flows

• Use clear step count (Step X of N).
• Use labeled progress rail/indicator when steps are discrete.
• Keep navigation predictable: back/next behavior should never surprise.

9. Accessibility

• Minimum practical touch target: 44dp.
• Do not rely on color alone for status.
• Preserve high contrast for all text tiers.
• Add meaningful contentDescription for icon-only controls.

10. Architecture Rules

• Durable UI state in MainViewModel.
• Composables: state in, callbacks out.
• No business/network logic in composables.
• Keep side effects explicit (LaunchedEffect, activity result APIs).

If style and implementation diverge, update both in the same change.
