Android Developer needed to setup and reskin an Envato (Codecanyon) Video/Voice Calling App Job Description: Hi I have purchased a complete Android Voice/Video calling application source code from Envato (Codecanyon). I need an experienced Android Developer to configure, reskin, and deploy this app for me. Your tasks will include: 1.Setting up the source code and linking it with my Firebase and Agora accounts. 2.Integrating the UPI Payment Gateway. 3.Changing the App Name, Package Name, Logo, and UI Colors (Reskinning). 4.Testing the app completely for any bugs. 5.Deploying the final app onto my Google Play Console. ⚠️ IMPORTANT PAYMENT TERMS (PLEASE READ CAREFULLY): The budget for this project is fixed at $50. The payment will be strictly divided into 2 to 3 Milestones. I will NOT release the full or final payment upfront. Funds will only be released after the app is completely tested, working 100% fine without bugs, and successfully live on the Play Store. You must hand over the final updated source code, keystore file (with passwords), and admin panel access before the final milestone release. Requirements: Strong experience with Android Studio, Java/Kotlin, or Flutter. Prior experience with Agora SDK and Firebase integration. If you agree to these payment terms and milestone conditions, please apply with your portfolio. Thanks!
