Android Action Game App Guidance

I have an idea for an Android-only action game and already own the core design assets, but no codebase yet. I need an experienced mobile-game professional to map out, in plain language, how I can turn those assets into a published title that earns steady revenue.

What I expect from you:
• A step-by-step development roadmap – toolchain selection (Unity, Unreal or other), team roles I’ll need, typical timelines and milestone breakdowns.
• A clear monetisation plan covering in-app purchases, rewarded ads, subscriptions or hybrid models, with projected CPI / LTV numbers so I can see which route makes sense for an action game.
• Launch and growth tactics: play-testing stages, Google Play submission, ASO, soft-launch regions, influencer or TikTok outreach, paid-ad funnels and community building.
• Post-launch optimisation tips: analytic KPIs to track, update cadence, live-ops ideas and strategies to keep ARPDAU rising.

Keep the advice actionable, beginner-friendly and focused on Android specifics. If you can illustrate examples from titles you have shipped, that will help me replicate proven methods. Deliver everything as a concise PDF guide and a follow-up call or chat session to clarify next steps.

I’m ready to move quickly once I have a solid, realistic plan in hand.
