claude-android-skill

von dpconde · dpconde/claude-android-skill

Teaches Claude Code to build modern Android apps the Google way — Clean Architecture, Compose, Hilt, Room, Flow, offline-first, multi-module by feature.

A skill that encodes modern Android best practices (mirroring the NowInAndroid reference) into Claude Code: Clean Architecture with UI/Domain/Data layers, MVVM + UDF, Jetpack Compose for UI, Hilt for DI, Room for persistence, Kotlin Flow for reactive streams, Retrofit for networking, and a multi-module feature-first project structure.

Öffne Claude Desktop → Settings → Developer → Edit Config. Nach dem Speichern neu starten.

Cursor nutzt das gleiche mcpServers-Schema wie Claude Desktop. Projektkonfiguration schlägt die globale.

Klicken Sie auf das MCP-Servers-Symbol in der Cline-Seitenleiste, dann "Edit Configuration".

~/.codeium/windsurf/mcp_config.json

      ],
      "_inferred": true
    }
  }
}

Gleiche Struktur wie Claude Desktop. Windsurf neu starten zum Übernehmen.

~/.continue/config.json
{
  "mcpServers": [
    {
      "name": "claude-android-skill",
      "command": "git",

        "~/.claude/skills/claude-android-skill"
      ]
    }
  ]
}

Continue nutzt ein Array von Serverobjekten statt einer Map.

        ]
      }
    }
  }
}

In context_servers hinzufügen. Zed lädt beim Speichern neu.

Anwendungsfälle

Praxisnahe Nutzung: claude-android-skill

Scaffold a new Android app with modern architecture

👤 Android developers starting a greenfield project ⏱ ~60 min intermediate

Wann einsetzen: You're starting a new app and don't want to make architectural mistakes you'll fix in 6 months.

Voraussetzungen
  • Skill cloned — git clone https://github.com/dpconde/claude-android-skill ~/.claude/skills/claude-android-skill
  • Android Studio + JDK 17 — Install latest stable Android Studio
Ablauf
  1. Ask Claude to scaffold the module structure
    Use claude-android-skill. Scaffold a multi-module Android app called 'HabitTracker' with features: home, tracking, settings. Compose UI, Hilt DI, Room DB, offline-first.✓ Kopiert
    → Modules :app, :core:database, :core:ui, :feature:home… generated
  2. Add first feature end-to-end
    Implement the tracking feature: data layer with Room entity, domain layer with use cases, UI with Compose and ViewModel. Include unit tests.✓ Kopiert
    → Files across 3 layers + tests all compile

Ergebnis: A running app that follows NowInAndroid-style patterns.

Fallstricke
  • Over-engineering a tiny app into 8 modules — Tell the skill explicitly: 'single-module is fine here' for simple projects
Kombinieren mit: filesystem · github

Migrate a Fragment/XML screen to Compose

👤 Android teams modernizing legacy screens ⏱ ~45 min intermediate

Wann einsetzen: You have an XML screen and want Compose without rewriting everything in one go.

Ablauf
  1. Analyze the existing screen
    Here's the Fragment + XML for SettingsScreen. Plan a Compose migration keeping the ViewModel intact.✓ Kopiert
    → Step plan: wrap in ComposeView, port Views, clean XML
  2. Apply the migration
    Implement step 1 — add ComposeView and move the header to Compose.✓ Kopiert
    → Hybrid screen works; subsequent steps staged

Ergebnis: A Compose screen with ViewModel contract preserved.

Fallstricke
  • State lost during migration — Keep the same ViewModel; only the UI layer changes
Kombinieren mit: github

Add offline-first support to an online-only feature

👤 Developers whose app breaks without network ⏱ ~90 min advanced

Wann einsetzen: You have a Retrofit-only feature and want cached / queued behavior.

Ablauf
  1. Introduce Room + repository
    Use claude-android-skill to convert the profile feature to offline-first. Add Room entity, repository returning Flow, and a sync worker.✓ Kopiert
    → Data layer restructured, repository is the single source of truth
  2. Wire UI to the Flow
    Update ViewModel to collect from the repository Flow; handle loading/empty/error states in Compose.✓ Kopiert
    → UI works offline on first launch after sync

Ergebnis: A feature that works in airplane mode.

Fallstricke
  • Conflict resolution forgotten — Decide the strategy up front: LWW, server-wins, or merged — the skill will prompt you

Fehlerbehebung

Häufige Fehler und Lösungen

Hilt compile error: missing @HiltAndroidApp

Ensure the Application class is annotated and declared in manifest

Prüfen: grep -r '@HiltAndroidApp' app/src/
Room schema mismatch on migration

Either provide a Migration, or set fallbackToDestructiveMigration in dev

Compose preview won't render

Add the Compose preview dependency and annotate @Preview correctly
