Frequently Asked Questions
Is this series really free?
Yes! All 5 parts are completely free to read. The only costs you’ll incur are: Google Cloud Platform (with $300 free credits), Play Store registration ($25 one-time fee), and optional backend hosting (~$5-20/month if you choose that security method).
Do I need prior AI experience?
No! We start from the absolute basics. You just need to know Android development (Java or Kotlin) at an intermediate level. Everything about AI, APIs, and Gemini is explained from scratch.
How long does it take to complete?
Reading time is about 3 hours total. Hands-on implementation takes 10-15 hours depending on your experience level. Most people complete it over 2-3 weekends.
Can I use this for commercial apps?
Absolutely! Everything in this series is production-ready. The security methods, architecture, and best practices are what we use in real commercial applications. The code is yours to use however you want (MIT license).
