Fix Payment Error & Integrate In-App Update Feature (Unity, Android)

Job ID: 39175755

Budget: ₹1,500 – ₹12,500 INR

I'm looking for an experienced Unity & Android developer who can integrate in-app update (download & install) feature and update my app to modify the PhonePe payment gateway.

Key Requirements:
-Implement an in-app update feature in a Unity-based Android app, allowing users to download and install the latest version directly from our server. The update button should check for new versions, prompt the user when an update is available, and handle the download and installation process smoothly.

- The payment page should open in the user's default browser. Currently, the payment page opens within the app, but due to NPCI guidelines, the UPI payment option isn't visible. I need this updated so the payment page opens in the user's default browser (Google Chrome, etc.) instead.

- Proper handling of payment status: After the payment, PhonePe redirects to a callback URL. The app needs to handle this correctly and reflect the payment status.

Ideal Skills:
- Proficiency in Unity engine & Android app development (Android Studio)
- Experience with payment gateway integration, specifically PhonePe

Budget & Timeline:
Rs. 6000-8000 and have to get the work completed by Saturday, 8th March.

Please let me know your availability for this task. Thanks!
