Custom Chromium webview provider in AOSP 9.0

[d...@vittegleo.com]

I'm was successfully building AOSP 8.1 with the stable version of Chromium 'monochrome_public_apk' target and replacing the standard AOSP webview with Chromium webview. To do this I was:

* Building Chromium the monochrome_public_apk target with this configuration:

target_os = "android"

target_cpu = "arm64"

is_debug = false

is_official_build = true

is_component_build = false

symbol_level = 0

ffmpeg_branding = "Chrome"

proprietary_codecs = true

android_channel = "stable"

android_default_version_name = "68.0.3440.81"
android_default_version_code = "344008152"

* Replacing the AOSP webview with Chromium in frameworks/base/core/res/res/xml/config_webview_packages.xml:

<?xml version="1.0" encoding="utf-8"?>

<webviewproviders>

    <webviewprovider description="Chromium" packageName="org.chromium.chrome" availableByDefault="true">

    </webviewprovider>

</webviewproviders>

* And including it in the AOSP build tree with this Android.mk file:

LOCAL_PATH := $(call my-dir)

include $(CLEAR_VARS)

LOCAL_MODULE := chromium

LOCAL_MODULE_CLASS := APPS

LOCAL_MULTILIB := both

LOCAL_CERTIFICATE := $(DEFAULT_SYSTEM_DEV_CERTIFICATE)

LOCAL_REQUIRED_MODULES := \

        libwebviewchromium_loader \

        libwebviewchromium_plat_support

LOCAL_MODULE_TARGET_ARCH := arm64

my_src_arch := $(call get-prebuilt-src-arch,$(LOCAL_MODULE_TARGET_ARCH))

LOCAL_SRC_FILES := prebuilt/$(my_src_arch)/MonochromePublic.apk

This process worked fine in AOSP 8.1, but for some reason the Chromium webview is no longer being registered in 9.0. Chromium is still showing up as an installed application, but it is just not registering as a webview. Any ideas?

You are building M68? P support was upstreamed in M69. See history here: crbug.com/850652

Thanks so much for the reply and link to this bug Bo! I'm kicking off a build with M69 and will see if that solves the issue for me.

Works again on M69! Thanks Bo!
