Android WebView App With File Transfer

@Proswift

Hi, You need an Android WebView app for EstiBill — not a basic URL wrapper. Must handle PDF downloads with the correct filename, camera/gallery/file uploads, WhatsApp/tel/external links, JS/cookies/sessions, progress bar, offline + Retry, Back history, exit confirm from Home, splash + icon from your logo, no extra native toolbar, Play-ready target SDK. Stack: Kotlin + Android Studio. Custom WebViewClient / WebChromeClient for downloads, file chooser, and intents. Permissions only when needed. I’ve built Android WebView apps with PDF download + upload/camera pickers for live sites before (same pattern as wrapping a responsive web app). Price: ₹1500.00 INR Timeline: 4–5 days after URL + logo Deliverables: full source, debug APK, release APK, AAB, README (URL, name, logo, splash, colours) Best regards

Hi, I can build you a production-ready Android WebView app for EstiBill that feels native and passes Google Play review. My approach will be Kotlin with AndroidX WebView. I will wrap your live EstiBill URL in a secure WebView with JavaScript, cookies, localStorage and sessions enabled so login and billing workflows work exactly like in Chrome. I will not add any extra toolbar since your web app already has its own UI. Key features I will implement and test on real device: 1. PDF Download: Custom DownloadListener with filename extraction from Content-Disposition so PDFs save with the correct name to Downloads. Runtime storage permission handled only when needed. 2. File Upload: WebChromeClient file chooser with support for camera capture, gallery pick and document picker via Intent chooser. 3. External Links: Intercept tel:, mailto:, whatsapp: and open in native apps. 4. UX: Progress bar during page load, branded splash screen with your logo, status bar and nav colors in EstiBill blue/white, offline screen with Retry button, and proper back stack. On home/dashboard back press I will show confirmation dialog "Do you want to exit EstiBill?" Yes/No. 5. Play Ready: Target latest SDK/API required by Play, signed AAB and APK, clean manifest, no crash on 30min test. Deliverables: Full editable Android Studio Kotlin source, release AAB and signed APK. Send me the EstiBill URL and logo when ready and I will start.

Hi, I'm a frontend developer specializing in React, Tailwind CSS, and responsive web design, with additional WordPress experience. While my core strength is building and styling web interfaces rather than illustration-heavy logo work, I can deliver clean, on-brand social media visuals, web banners, and landing-page graphics quickly and affordably — especially anything that needs to translate directly into a working site or web asset. I keep files layered and editable, and I'm comfortable with quick-turnaround, budget-scoped work in the $2–50 range you described. Happy to start with a small trial task so you can see the quality and speed before committing to more. What's the first piece you'd like done?
