-Building the Chromium-based WebView in AOSP is no longer supported. WebView can
-now be built entirely from the Chromium source code.
-
-General instructions for building WebView from Chromium:
-https://www.chromium.org/developers/how-tos/build-instructions-android-webview
-
-For questions about building WebView, please see

-
-------
-
-The prebuilt APKs here are built from Chromium upstream sources; check the
-commit messages to see the version number for a particular prebuilt (the version
-number looks like 74.0.3729.127 and this is also the name of the tag in the
-Chromium git repository).
-
-If you want to build your own WebView, you should build the latest stable
-version, not the version published here: newer versions have important security
-and stability improvements.
-
-However, if you want to reproduce the native library (libwebviewchromium.so)
-contained in these prebuilt APKs, you should be able to do so with the following
-GN arguments:
-
-target_os = "android"
-is_debug = false
-is_component_build = false
-is_official_build = true
-is_chrome_branded = false
-use_official_google_api_keys = false
-exclude_unwind_tables = true
-ffmpeg_branding = "Chrome"
-proprietary_codecs = true
-enable_remoting = true
-
-as well as specifying the appropriate target_cpu, which should be one of
-"arm", "arm64", "x86" or "x64".
-
-To build a complete WebView APK it is necessary to also set android_sdk_release
-to the current Android SDK version (for example, "q"). However, it's not always
-possible to do this successfully for all public Chromium versions: we are not
-able to publish the required Java code changes to support a given Android
-version until after that Android version's SDK has been publicly released, and
-so the public versions of Chromium do not always support the latest version of
-Android.
