AOSP Android 6.0에서 WebView 업데이트

Question

AOSP Android 6.0 (Marshmallow)을 기반으로하는 장치에서 작업 중입니다.
최신 JavaScript를 사용하기 위해 표준 Android webview를 최신 버전으로 업데이트하고 싶습니다.
이 경우 나는 external/chromium-webview/prebuilt/arm64/webview.apk을 최신 버전으로 바꿨습니다.
에서 config_webViewPackageName의 값을 com.android.webview에서 com.google.android.webview으로 변경했습니다. 하지만 내가 같은 오류가있어 (예를 들어 표준 안드로이드 브라우저) 웹보기를 사용하여 일부 응용 프로그램을 시작하려고 할 때 :

누군가가 이러한 문제에 직면 했을?
