Project description:
"I converted my React JS website into an Android APK, but Google sign-in breaks once it’s inside the app. On the web, the flow built with react-google-login works perfectly; however, the APK relies on a custom-wired version of the same logic and the OAuth pop-up never completes, leaving users stuck at the login screen.

I need you to trace the exact point of failure—whether that’s an OAuth redirect, SHA-1 mismatch, missing intent filter, or a WebView setting—and implement a rock-solid fix so users can authenticate with their Google accounts from the APK just as smoothly as they do in the browser.

Core expectations
• Diagnose and correct the Google login flow inside the existing Android build.
• Keep the current React codebase intact where possible, but refactor or swap in a proven library if that’s the fastest route to stability.
• Confirm everything against Google Console credentials, update any SHA-1 or OAuth redirect URIs, and produce an updated, installable .apk for testing.
• Hand back concise notes on the changes so future builds stay compatible.

If you’ve already wrestled with Google OAuth inside WebView-wrapped React apps, this should feel familiar. I’m happy to provide the current repo, keystore info, and test accounts the moment we kick off." (client-provided description)
