| 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 |
| https://groups.google.com/a/chromium.org/forum/#!forum/android-webview-dev |
| |
| ------ |
| |
| 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. |
