 [Android WebView](https://developer.android.com/reference/android/webkit/WebView.html)
 is a system framework component. Since Android KitKat, it is implemented using
 Chromium code (based off the [content module](https://dev.chromium.org/developers/content-module)).
-It is possible to test modifications to WebView using a simple test shell. The
-WebView shell is a view with a URL bar at the top (see [code](https://code.google.com/p/chromium/codesearch#chromium/src/android_webview/test/shell/src/org/chromium/android_webview/test/AwTestContainerView.java))
-and is **independent** of the WebView **implementation in the Android system** (
-the WebView shell is essentially a standalone unbundled app).
-As drawback, the shell runs in non-production rendering mode only.
 
-```shell
-ninja -C out/Release android_webview_apk
-build/android/adb_install_apk.py out/Release/apks/AndroidWebView.apk
