# OVERVIEW I believe you have noticed that in the latest Android 4.4 Kitkat version, the WebView implementation based on Android WebKit was replaced with the WebView implementation based on Chromium. In the previous chapter, the author also introduced that the chrome-based WebView implementation will become the default implementation method on the

An important update for Android KitKat is that WebView uses the Chromium/blink rendering engine, which briefly describes the main features of the new version of WebView, where further improvements are needed, and the code structure of WebView.WebView Past LifeWebView is a very important system component on the Android platform that embeds a widget view of a displ

Chromium Android WebView is a Chromium designed for Android WebView to provide a package layer for content. As a whole, it can be understood as a specialized embedder, which can be summed up as:1. The content and partial browser components are packaged into Java implementations for WebView functions Aosp WebView calls.

Android offers webview based on the chromium implementation from 4.4. Previously WebView was based on WebKit implementations. WebKit provides basic functions such as Web page parsing, layout and plotting, and JS running. Chromium provides infrastructure for WebView process, threading, and rendering on a webkit basis. Therefore, WebView based on

It should be known that Phonegap/cordova (Android) just added a shell to WebApp, that is WebApp run on WebView. Android's WebView is a webkit kernel, but there is a difference between the WebView and the mobile chrome kernel. People who have used the mobile version of Chrome can obviously feel that performance is much smoother than their own browser (or WebView). Android 4.4 and above with the webview is a

Recently, chromebook has arrived. Lu Bin, the android leader, has been transferred. The owner of Chrome browser is the owner. Chromebook has been suspended for two or three years. The last chromeos was launched using WebKit as the shell, which proved to be ineffective. In the past two or three years, more voices have been heard: chromeos will be abandoned, and Android should be more unified. According to my

The principle of this thing is this: the official Android system does not support the modification of the system default font, all can be modified by the OEM manufacturers to modify the framework layer of code, while integrating a high-privileged pre-installed application services.How to do it?It's really simple: Modify the Android.content.res.Configuration class, and the configuration class saves the system level that affects the settings for all Act
