Hi there, I understand you need to finalize Google Sign-In setup for your already completed mobile app across both Android and iOS platforms. Based on your description, you've created the OAuth 2.0 client IDs in Google Cloud Console, which means we're at the final integration stage. For Android, I'll configure the google services json file and implement the necessary dependencies along with proper callback handling. For iOS, I'll set up the plist configuration and handle the authentication flow using Google Sign-In SDK. Since you mentioned PHP as well, I can also assist with backend token validation if needed. The implementation will include proper error handling, user session management, and ensuring the sign-in process works seamlessly across both platforms. I'll make sure everything is production-ready with proper security measures and follows platform-specific guidelines. This is a straightforward integration task that I can complete efficiently while ensuring compatibility with your existing codebase. Best Regards, Khorshed Alam, RS Software

Hi there, I can see the real blocker isn’t the app itself , it’s the last authentication chain where one mismatched SHA-1, bundle ID, or reversed client ID can quietly stop release. I’ve handled Google/Firebase sign-in setups before across Android and iOS, and I’ll trace the OAuth client IDs, Firebase config, Play Console settings, and Apple-side Firebase configuration to make sure production login works cleanly on both tracks. I’ll also prepare a short handoff note so you know exactly where each setting lives if keys ever need rotation. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. I can start by verifying the current console values against the app build, then I’ll test the live flow and confirm the release path is free of “app not configured” errors. Can you share which Firebase project, bundle ID, Android package name, and Play/App Store release tracks are currently connected so I can verify the live auth path end-to-end? Please note, I’ll also document the exact steps for future maintenance so this stays manageable after handoff. Looking forward to your reply so we can finalize the exact plan. Best regards, Asad

@denisSolution

Hi, I'm Denis, a developer experienced with mobile authentication setups and Firebase integrations. Google Sign-In is tricky because mismatched credentials between Google Cloud Console, Firebase, and the store consoles can break production builds. Your next steps are focused on validating the OAuth client details, enabling the sign-in method in both Play and Apple consoles, and ensuring the Firebase configuration aligns with what’s live. I’ll review the SHA-1 fingerprints, bundle IDs, and reversed client IDs against your app’s code to confirm they match across all three systems. Then I’ll enable Google Sign-In in both console environments and push the updated configuration to production. After testing the live flow, I’ll document where each setting lives so you can manage or rotate keys later. The main risk is inconsistent credentials causing “app not configured” errors in production, so I’ll verify each value before deployment. I can start working right away. Let's connect and discuss the details. Thanks, Denis.

@AndrewJSMAN

I’ve deployed Google Sign-In across Android and iOS in multiple Firebase projects, so this is straightforward. I’ll verify the OAuth client configs—SHA-1 hashes, bundle IDs, reversed client IDs—against your Firebase and codebase to ensure parity. Then I’ll enable Google Sign-In in Google Play Console and Apple via Firebase Auth settings, test the production flows end-to-end, and push the validated config to both store tracks. The handoff will cover key locations in Google Cloud Console, Firebase, and Play Console for future key rotations. I can start immediately. Thanks, Andrii.

@muhammadsaad90

Hi, I’ve handled similar Google Sign-In/Firebase configurations where the issue was usually a mismatch between OAuth credentials, package/bundle identifiers, SHA-1 fingerprints, or platform configuration. I’d audit each value across Google Cloud, Firebase, Android, and iOS, then correct only the configuration causing the production authentication failure. I’ll verify the Android SHA-1/package setup, iOS bundle/reversed client ID configuration, required console settings, and production credentials. Then I’ll test the live sign-in flow on both platforms and provide a concise handoff document covering where everything is managed. Best Regards, Muhammad Saad K

@raghuch2415

Hello there, As per your requirement, I can take care of the Google Sign In production configuration for both Android and iOS and resolve the remaining authentication setup without unnecessary code changes. I will verify the SHA 1 fingerprints, package and bundle identifiers, OAuth client IDs, reversed client ID, Firebase configuration, Google Cloud settings, and store related configuration, then update and deploy the required production settings. I will also test the complete sign in flow to ensure there are no configuration errors on either platform. I will provide a concise handoff document covering Google Cloud Console, Firebase, and Play Console settings, including where to find and rotate the credentials later. Since the application is already built, I can focus directly on the configuration and production release, keeping the process quick and clean. Thanks, Raghu.

@lazarr4

Hello, the tricky bit here is making sure the OAuth client fingerprints and bundle IDs are consistent across Google Cloud Console, Firebase, and both mobile store consoles—even a small mismatch shows users "app not configured" errors. I’ve set up Google Sign-In in Firebase projects before, mainly dealing with Android and iOS OAuth flows through Google Play Console and Apple’s App Store Connect. The last project required fixing mismatched SHA-1 hashes and bundle IDs that were causing auth failures in production. I’d start by auditing the existing OAuth client IDs in Google Cloud Console against Firebase and your codebase. Then I’d walk through Google Play Console and Apple App Store Connect to verify the linked credentials, test the sign-in flow on both stores’ production tracks, and finally deploy the validated configuration. A short doc with pointers to where each setting lives will go a long way if you ever need to rotate keys later. One dependency is access to your Google Cloud Console, Firebase project, Google Play Console, and App Store Connect. If any of the OAuth client IDs were created with the wrong package names or fingerprints, we’ll need to update them in Google Cloud first. Thanks, Lazar.

@chandibraheem58

Hi, Your app is already built, so the release blocker is purely the Google Sign-In configuration. I’ll verify the Android SHA-1/client IDs, iOS bundle ID and reversed client ID, then cross-check Google Cloud, Firebase, Play Console and Apple configuration for any mismatch. I’ll apply the required console changes, push the updated configuration, and verify the live Google Sign-In flow on both Android and iOS production tracks. No unnecessary code changes. I’ll also provide a short handoff document showing where each important setting lives so future credential/key rotation is straightforward. Can you provide temporary Firebase, Google Cloud and app-store access so I can audit the OAuth configuration and remove the production sign-in blocker? Best Regard, Chand

I completely understand the frustration of being held back by seemingly small tasks yet critically important to the completion and successful launch of your app. It's incredibly rewarding for me, with over 8 years of experience in Android development, mobile app development, and PHP, to tackle these kinds of projects and help clients like you reach their goals. While my primary focus is on native iOS and Android, I'm also experienced with a range of other frameworks, including Firebase which is an essential part of a smooth Google Sign-In setup. I've worked extensively with databases such as MySQL, PostgreSQL, MongoDB; this complements well when it comes to verifying client details and ensuring a clean deployment. Moreover, working across the full development stack has given me a comprehensive understanding of not just the code but also backend requirements, like rotating keys. This means that in addition to getting your Google Sign-In set up, I can deliver a useful handoff document outlining all the relevant settings within Google platforms if needed in case you'd want I |
