Playwright can automate Chrome for Android and Android WebView on a physical Android device or an AVD emulator by connecting through authenticated ADB. Its Android support is experimental, and it targets browser pages—not every part of a native Android app’s interface. For Chrome, discover the device and launch its browser; for an app WebView, expose the WebView for debugging and attach to it by package name.
What Playwright can test on Android
Playwright’s documented Android API supports Chrome for Android and Android WebView. The target can be real hardware or an Android Virtual Device (AVD) emulator. The API can discover connected devices, report their model and serial, run shell commands, take device screenshots, launch Chrome, attach to WebViews, and install APK files. See the Playwright Android guide and AndroidDevice reference.

This is not a general-purpose way to automate every native Android screen or control. It is a browser and WebView testing workflow. Playwright explicitly describes Android automation as experimental, so confirm it fits your required coverage and tolerate changes or gaps.

Prepare a real device or emulator
- Set up an Android device or AVD emulator and enable developer access.
- Install and start ADB on the host, connect the target, and approve its debugging authorization prompt. Check that ADB can see it with
adb devices; the device should appear as authorized rather than offline or unauthorized. - Install Chrome 87 or newer on the target. Playwright’s guide currently names this as a requirement; check the current guide because version and setup requirements may change.
- On the Android device, open Chrome, visit
chrome://flags, find Enable command line on non-rooted devices, enable it, and relaunch Chrome if prompted. - Keep the target awake while taking device screenshots. The guide notes that screenshots require an awake device and that not all tests have been run against the device.
Playwright uses ADB; it does not support operating over raw USB directly. Use the documented ADB connection path even when the device is physically plugged into the host.

Run a test in Chrome for Android
The Android API is exposed as the underscored _android export from the playwright package. This runnable Node.js script selects the first connected target, launches Chrome, opens a page, checks its title, and closes the browser context and device.
const { _android: android } = require('playwright');
(async () => {
const devices = await android.devices();
if (devices.length === 0) {
throw new Error('No authorized Android device or emulator found');
}
const device = devices[0];
console.log(`Connected to ${device.model()} (${device.serial()})`);
let context;
try {
context = await device.launchBrowser();
const page = await context.newPage();
await page.goto('https://example.com');
console.log(await page.title());
await page.screenshot({ path: 'android-page.png' });
} finally {
if (context) await context.close();
await device.close();
}
})();The device methods and returned persistent browser context are documented in the Android guide and AndroidDevice reference. The script checks for the no-device case rather than destructuring an empty device list. If you have multiple targets attached, identify the intended device by its model or serial before running the test; do not assume the first device is the one you want.

Automate an app’s Android WebView
For WebView coverage, the app must be running and its WebView must be exposed to Chrome DevTools. In the app’s development build, enable debugging in code, for example:
if (BuildConfig.DEBUG) {
WebView.setWebContentsDebuggingEnabled(true);
}Android Developers recommends limiting WebView debugging to development builds. A manifest debuggable flag does not enable WebView debugging by itself. See Android’s Chrome DevTools debugging guidance.
After starting the app and its WebView on the connected target, use the package name to attach and then work with its page:
const { _android: android } = require('playwright');
(async () => {
const devices = await android.devices();
if (devices.length === 0) {
throw new Error('No authorized Android device or emulator found');
}
const device = devices[0];
try {
const webview = await device.webView({ pkg: 'your.package' });
const page = await webview.page();
await page.waitForLoadState('domcontentloaded');
console.log(await page.title());
await page.screenshot({ path: 'webview-page.png' });
} finally {
await device.close();
}
})();Replace your.package with the app’s application ID. The app must already be open with an inspectable WebView; if the target exposes more than one WebView, identify the intended one using the available WebView information in your setup. Playwright’s Android API documents device.webView({ pkg }) and the WebView page workflow in its Android guide and AndroidDevice reference.

Choose Android automation or device emulation
Regular Playwright device emulation configures browser parameters such as user agent, viewport and screen size, touch support, locale, timezone, geolocation, permissions, and color scheme. It is useful for responsive-page checks, but it does not connect to an Android operating system over ADB. Use the Android API when the test specifically needs the documented Chrome for Android or app WebView target; use emulation when browser-profile coverage is sufficient. See Playwright’s emulation guide.
| Approach | What it exercises | What it requires | Best fit |
|---|---|---|---|
| Playwright Android API | Chrome for Android or an exposed app WebView on an Android target | Authenticated ADB connection; Chrome setup for browser tests; app-side WebView debugging for WebView tests | Checks that need the documented Android browser or WebView environment |
| Playwright device emulation | Browser behavior with configured device-like parameters | A Playwright browser context and selected emulation settings | Responsive design and browser-parameter coverage without an ADB-connected Android OS |
Troubleshoot common failures
- No devices returned: Run
adb devices, confirm the daemon is running, reconnect the device or restart the emulator, and accept the authorization prompt on the device. The documented workflow requires an authenticated ADB target. - Target appears unauthorized or offline: Resolve the ADB state first—accept the host key prompt, reconnect, or restart the ADB daemon—then check the device list again.
- Chrome does not launch: Confirm Chrome is installed and meets the version requirement in Playwright’s current Android guide, and enable Enable command line on non-rooted devices in
chrome://flags. - WebView cannot be found: Verify the app is running, the package name is correct, and the WebView is currently present. Ensure the app’s code enables
WebView.setWebContentsDebuggingEnabled(true)in the development build. - Page operations time out or show unexpected state: Check that the app or browser has finished navigating and that the target has network access. Add an explicit wait for the page condition your test needs rather than relying on a fixed delay.
- Device screenshot is blank or unavailable: Make sure the device is awake; Playwright’s Android guide calls this out as a screenshot requirement.
- Native controls are outside the test: The documented workflow automates Chrome and WebView pages, not arbitrary native Android UI. Keep native-interface coverage in a suitable native automation workflow.
Performance, reliability, and cost considerations
Using an AVD avoids requiring a physical phone for every run, while real hardware is appropriate when the test needs a device rather than a simulated Android target. Playwright’s documentation does not publish Android automation reliability rates or a guarantee that every test works on-device. Because support is experimental and the guide cautions that not all tests have been run, treat device coverage as a test environment to validate against your own browser, app, and CI needs.

The Android API also documents launching an Android server and connecting a client through its WebSocket endpoint, with device serial selection when multiple devices are attached. This is infrastructure context, not confirmation that a particular hosted-device service is compatible. The Android workflow itself does not state a Playwright usage price; the costs of a physical device, emulator infrastructure, and CI are separate from the API documentation.
Or skip the browser setup
If you need a screenshot of a public web page rather than an Android-specific browser or app WebView test, ScreenshotNeo can return a screenshot or PDF from one GET request. It is not a replacement for exercising an Android OS device. See the ScreenshotNeo API documentation for request options.
curl -G "https://api.screenshotneo.com/v1/shot" -d access_key=YOUR_API_KEY --data-urlencode url=https://example.com -o shot.webpScreenshotNeo removes cookie banners, newsletter popups, and chat widgets before the shot. Bot checks, blank pages, failed loads, timeouts, and cache hits are not billed. Its MCP server lets AI agents use screenshot tools, and the free plan includes 1,000 screenshots per month with no card; paid plans start at $5 for 3,000. Sign up for free and get 1,000 screenshots a month with no card.

Frequently Asked Questions
Can I use a physical Android phone instead of an emulator?
Yes. Playwright’s Android device interface supports connected real hardware as well as emulated devices, provided the target is available through authenticated ADB.
Does Playwright Android automation cover every native app screen?
No. The documented Android workflow targets Chrome for Android and Android WebView pages, not arbitrary native Android UI.
Can I test an app WebView without changing the app?
The documented DevTools workflow requires the app to enable WebView debugging in code. Android Developers recommends enabling it only in development builds.
