I’m looking for a headless browser solution that can run on Android devices and handle JavaScript execution properly. So far I’ve experimented with a couple options but ran into some limitations. HTMLUnit seemed promising at first but I couldn’t get it working on the Android platform at all. Then I switched to JSoup which actually performs really well for basic web scraping tasks, but the problem is it can’t execute JavaScript which is essential for my use case since many modern websites rely heavily on JS for content rendering. I need something that combines the reliability of JSoup with JavaScript capabilities. Has anyone found a good headless browser library that actually works on Android and can process JavaScript? What are some alternatives I should consider testing?
PhantomJS was the go-to for this, but it’s dead now so you’ll need something else. I’ve had good luck with Chrome Custom Tabs for basic JavaScript stuff on Android. Not truly headless, but you can hide it from users and it handles modern JS frameworks fine. Another option that’s worked for me - remote WebDriver with Selenium. Run the browser on a server and control it from your Android app via HTTP. More setup upfront, but you get full Chrome power without Android’s browser limits or performance headaches.
Running browsers on Android is a nightmare. You’re constantly battling memory limits, battery drain, and weird behavior across different Android versions.
I run into this at work when teams want to scrape data from mobile apps. What actually works is moving browser automation to the cloud instead of wrestling with it locally.
Run your scraping workflows remotely where you’ve got real Chrome instances with unlimited resources. Your Android app just sends requests to trigger workflows and gets clean JSON back.
You’ll get reliable JavaScript execution, better performance, and users won’t watch their battery die from background browser processes. Plus you can handle complex stuff like dynamic loading, form submissions, and multi-step flows that would be hell on device.
Keeps your app lightweight while giving you full browser capabilities. Way cleaner than cramming WebView hacks into your Android code.

Try Android’s built-in WebView with JavaScript enabled and visibility set to gone. I’ve used this in production for two years - it handles most modern JS frameworks just fine. You’ll need to manage the WebView lifecycle properly and implement custom WebViewClient callbacks to capture the rendered content. For simpler cases, OkHttp + Rhino JavaScript engine works great. It’s not a full browser but executes basic JavaScript and handles dynamic content. Way smaller footprint than full browser solutions and runs well on older devices. If you need something more powerful, run Node.js with Puppeteer on a local server and use REST API calls. Sounds like overkill but the latency is surprisingly low on local network and you get full Chromium capabilities.
WebView works but you’ll hit scaling problems fast when scraping multiple sites or handling complex stuff.
Had this exact issue last year building a data collection system. Started with WebView but quickly realized I needed something more robust for automation at scale.
Game changer was moving the heavy lifting off the device completely. Instead of running a headless browser on Android, I set up automated workflows in the cloud that just send processed data back to the app.
This gives you full Chrome capabilities with JavaScript execution, better performance, and doesn’t kill your battery. Plus you can handle way more complex scenarios - waiting for elements, multiple pages, CAPTCHAs.
Your Android app just triggers the workflow and gets clean data back. Way more elegant than cramming a full browser engine onto mobile.

Check out gecko view if you’re cool with Mozilla’s engine over chromium. JS performance is solid and Android support beats most other options. Heavier than jsoup but way lighter than a full webview.
have u checked out webview with headless mode? i use it in my android app and it runs js pretty well. it’s kinda tricky to set up but once u get it goin its really reliable for most sites.
