1 Building the Chromium-based WebView in AOSP is no longer supported. WebView can 2 now be built entirely from the Chromium source code. 3 4 General instructions for building WebView from Chromium: 5 https://www.chromium.org/developers/how-tos/build-instructions-android-webview 6 7 For questions about building WebView, please see 8 https://groups.google.com/a/chromium.org/forum/#!forum/android-webview-dev 9 10 ------ 11 12 The prebuilt APKs here are built from Chromium upstream sources; check the 13 commit messages to see the version number for a particular prebuilt (the version 14 number looks like 74.0.3729.127 and this is also the name of the tag in the 15 Chromium git repository). 16 17 If you want to build your own WebView, you should build the latest stable 18 version, not the version published here: newer versions have important security 19 and stability improvements. 20 21 However, if you want to reproduce the native library (libwebviewchromium.so) 22 contained in these prebuilt APKs, you should be able to do so with the following 23 GN arguments: 24 25 target_os = "android" 26 is_debug = false 27 is_component_build = false 28 is_official_build = true 29 is_chrome_branded = false 30 use_official_google_api_keys = false 31 exclude_unwind_tables = true 32 ffmpeg_branding = "Chrome" 33 proprietary_codecs = true 34 enable_remoting = true 35 36 as well as specifying the appropriate target_cpu, which should be one of 37 "arm", "arm64", "x86" or "x64". 38 39 To build a complete WebView APK it is necessary to also set android_sdk_release 40 to the current Android SDK version (for example, "q"). However, it's not always 41 possible to do this successfully for all public Chromium versions: we are not 42 able to publish the required Java code changes to support a given Android 43 version until after that Android version's SDK has been publicly released, and 44 so the public versions of Chromium do not always support the latest version of 45 Android. 46
