Hello, I have extensive experience (over 10 years of full-cycle development), I will help you with your question.

8 years in mobile development, I know the current market requirements at the moment. Besides authentication (I can do it without problems), the task will be to assemble a team of testers, as well as prepare various declarations and policies. I know how to go through all this, I regularly publish applications for clients.

Good day, I can take a look tomorrow. What is the theme of the application? Is the description, screenshot, and privacy policy already ready for the Play Market?

I will help with publishing in Play Console and will figure out Google Sign-In on the client side. Typical problems when transferring from iOS include incorrect SHA-1 in Firebase, incorrect client_id in google-services.json, or absence of OAuth consent screen in Cloud Console. All of this can be resolved in 1-2 hours.

Show what error occurs during authentication — logcat or screenshot?

I will set up the Firebase connection and Cloud Console for the proper functioning of OAuth 2.0 in your Kotlin code and accompany the publishing process to a successful release on Google Play.

What method are you currently trying to fix Developer Error 10: have you entered the SHA-1 fingerprints for the release and Google Play signing key in the Firebase console, or are you still searching for a bug in the code while Google silently blocks your request due to certificate mismatch?

Budget and deadlines are in personal correspondence. 🤝

Hello,

I’m an experienced Android developer with a strong background in Kotlin and hands-on work with Firebase, Google Cloud Console, and the Play Console. I’d be glad to help you get your app ready for release and guide you through the entire publication process.

From what you described, I can assist with:

Debugging and fixing Google Sign-In issues on the client side (including OAuth configuration, SHA-1 setup, and Firebase integration)
Verifying whether any misconfiguration might also affect the server side
Reviewing your current Firebase and Google Cloud setup to ensure everything aligns correctly
Preparing your app for Play Store submission (signing, builds, release tracks, policies, etc.)
Walking you through the Play Console process step by step so you can confidently manage future releases

I’ve worked on similar migrations (including Swift → Kotlin rewrites), so I understand the common pitfalls—especially around authentication and environment configuration.

If you’d like, we can start with a quick review of your current setup and identify exactly where the authentication flow is breaking.

Looking forward to collaborating.
