Update Razorpay Key in Kotlin App

Job ID: 39751421

Budget: ₹100 – ₹400 INR

My Android app is already live on Google Play and built entirely in Kotlin. It still points to the Razorpay test credentials; I now have the production (live) key and just need it swapped in. No UI tweaks, feature additions, or version bumps beyond what is strictly required for Play Console submission.

You’ll receive:
• The full Android Studio project on Git (or ZIP, whichever you prefer)
• The new Razorpay live key/secret
• My Google Play developer-account access for uploading the release

What I need from you:
• Replace the test key with the live one, adjust any related initialization or Gradle configs, and verify that a live payment succeeds in the sandbox first transaction.
• Build and sign a new AAB/APK, increment the version, and upload it to the production track (or guide me through the final click if you prefer).
• Provide a brief note on the exact files changed so I can track the update.

This is a focused task, so a quick turnaround is ideal.
