Launch checklist
WebView App Launch Checklist: Security, Navigation, and Reliability
Use this checklist to test authentication, downloads, uploads, links, permissions, errors, and app-store readiness before launch.
Security and authentication
Use HTTPS everywhere, protect session cookies, validate deep-link parameters, and keep secrets out of website JavaScript and app configuration that can be extracted from a client.
Test sign-in, sign-out, password reset, social authentication, expired sessions, multi-factor prompts, and any redirects that leave and return to the app.
Navigation and back behavior
Confirm that app bar actions, bottom tabs, drawer items, website links, and the Android back button produce predictable results. Users should not become trapped in redirects or exit unexpectedly from a form.
Decide which domains stay inside the app and which open in an external browser. Treat payment, identity, and document links deliberately.
Files, media, and permissions
Test authenticated downloads with cookies and headers, file uploads from camera and storage, media playback, microphone access, location prompts, and QR scanning. Include filenames with spaces and large files.
Check permission denial and permanent denial states. A clear explanation and a path to device settings are better than repeated prompts.
Loading and failure states
Slow networks should show useful progress without covering the app forever. Pull-to-refresh, full-screen loaders, and retry screens need timeouts so one failed request cannot leave the interface stuck.
Test airplane mode, DNS failure, server errors, expired certificates, and returning online after the app has already shown an error.
Release operations
Verify icon quality, splash behavior, package name, version code, signing certificate, analytics environments, notification credentials, and store disclosures. Keep a copy of every release artifact and its build settings.
Use an internal test group before production, monitor crashes and web errors, and document how to disable or replace external SDK credentials when needed.
