| # Android WebView |
| |
| To run WPT on WebView on an Android device, some additional set-up is required. |
| |
| Currently, Android WebView support is experimental. |
| |
| * Please check [Chrome for Android](chrome_android) for the common |
| instructions for Android support first. |
| |
| * Install an up-to-date version of system webview shell: |
| * Go to |
| [chromium-browser-snapshots](https://commondatastorage.googleapis.com/chromium-browser-snapshots/index.html?prefix=Android/) |
| * Find the subdirectory with the highest number and click it. |
| * Download `chrome-android.zip` file and unzip it. |
| * Install `SystemWebViewShell.apk`. |
| * On emulator, system webview shell may already be installed by default. Then |
| you may need to remove the existing apk: |
| * Choose a userdebug build. |
| * Run an emulator with |
| [writable system partition from command line](https://chromium.googlesource.com/chromium/src/+/HEAD/docs/android_emulator.md/) |
| |
| * If you have an issue with ChromeDriver version, try removing |
| `_venv/bin/chromedriver` such that wpt runner can install a matching version |
| automatically. Failing that, please check your environment path and make |
| sure that no other ChromeDriver is used. |
| |
| Example command line: |
| |
| ```bash |
| ./wpt run --test-type=testharness android_webview <TESTS> |
| ``` |
| |
| * Note that there is no support for channel or automatic installation. The test |
| will be run against the current WebView version installed on the device. |
| |
| * Reftests are not supported at the moment. |
