1Building the Chromium-based WebView in AOSP is no longer supported or required. 2WebView can now be built entirely from the Chromium source code. 3 4Docs on how to build WebView from Chromium for use in AOSP are available here: 5https://chromium.googlesource.com/chromium/src/+/HEAD/android_webview/docs/aosp-system-integration.md 6 7For questions about building WebView, please contact our mailing list: 8https://groups.google.com/a/chromium.org/forum/#!forum/android-webview-dev 9 10--- 11 12The prebuilt APKs provided here are built from Chromium upstream sources; you 13should check the commit message to see the version number for a particular 14prebuilt. The version number is formatted like "12.0.3456.789" and matches the 15tag in the Chromium repository it was built from. 16 17If you want to build your own WebView, you should generally build the latest 18stable version, not the version published here: newer versions have important 19security and stability improvements. 20
