I need a focused Android developer who can wrap my existing web application inside a high-performance WebView while keeping usability and navigation at the centre of the experience. The core requirement is an immersive full-screen mode that hides the status bar on every device and orientation, making the site feel entirely native. A smooth pull-to-refresh gesture must also be baked in so users can reload content with a single swipe. Beyond those two must-haves, the WebView should: • Load pages quickly and cache assets efficiently. • Preserve session data securely through DOM storage. • Handle file uploads from the device (images, docs, etc.). • Respect Android’s back button to step through web history gracefully. Please build in Android Studio using current best practices (Kotlin preferred, though Java is acceptable). Once finished, I expect a clean, well-commented project that I can open, rebrand, and publish to Google Play without additional tweaks. If you’ve shipped similar wrappers or hybrid apps before, share a brief example and the turnaround time you can commit to.
