1Building the Chromium-based WebView in AOSP is no longer supported. WebView can 2now be built entirely from the Chromium source code. 3 4General instructions for building WebView from Chromium: 5https://www.chromium.org/developers/how-tos/build-instructions-android-webview 6 7------ 8 9The prebuilt libwebviewchromium.so included in these APKs is built from Chromium 10release tag 61.0.3163.98, using the GN build tool. To match our build settings, set: 11 12target_os="android" 13is_debug=false 14is_official_build=true 15is_chrome_branded=false 16use_official_google_api_keys=false 17exclude_unwind_tables=true 18enable_resource_whitelist_generation=true 19ffmpeg_branding="Chrome" 20proprietary_codecs=true 21enable_remoting=true 22 23in your GN argument file before building. 24 25------ 26 27Due to WebView API changes in the O-MR1 release, the Java code in the Chromium 283163 branch is not compatible with O-MR1. We'll be working on upstreaming 29the O-MR1 specific Java changes to Chromium once the final O-MR1 SDK is released. 30 31------ 32 33For questions about building WebView, please see 34https://groups.google.com/a/chromium.org/forum/#!forum/android-webview-dev 35
