What is Android System WebView for and if it can be removed

To make Android easier to update and keep safe on all phones, Google has detached some of its critical parts, making them applications that update automatically from the Google Play Store.
We have seen, for example, what the Google Play Services app is for, without which it would not be possible to use any Google app.
Another mysterious application present in many Android smartphones is the one called Android System WebView, which is updated very often and which appears in the tab on the Play Store with a somewhat vague description: " system component with Chrome technology that allows Android apps to show web content ... ".
This application is pre-installed in many models of Android smartphones, but as it remains hidden (starting from Android Nougat) and cannot be used directly, i.e. it cannot be found in the list of applications and cannot be started as it would be done with Chrome or other browsers, you may be wondering what it does and if it was possible to uninstall and remove it in case you need memory space.
In general, the " Android System Webview " app should be kept, even if it doesn't seem to do anything special.
WebView is basically a web browser, which however does not live a life of its own, but relies on other apps.
The purpose and the reason why this Android System WebView application exists is to provide a browser for applications .
In other words, when on an app like Facebook (even if Facebook also has its internal browser if in the settings you disable the option to open links outside) you touch to open an external link (for example a Navigaweb article ), the system can use the System WebView web page viewer within the same app you are using, without opening it in Chrome or Firefox.
In practice it is a mini-browser that is based on Chrome, with all the features of a browser including history, functions for zooming in and out, text search and so on.
If there were no Android System WebView, every link that opens from an application like Facebook would be opened on the default browser (for example Chrome) and then when you want to return to Facebook, you should close the browser.
To simplify this process, the System WebView allows you to open links within the app itself, with a button to quickly return to the app.
Android System WebView is therefore a hidden app that does not require any configuration, which is automatically used by the apps that support it and runs in the background.
Note that not all apps support WebView, which is why links are sometimes opened in the default browser anyway.
In some cases, then, apps can have their own web page viewer and ignore any browser.
