Google announced today that is introducing Safe Browsing on WebView. According to Google, Google Play Protect is bringing Safe Browsing to WebView by default, starting in April 2018 with the release of WebView 66.
Nate Fischer, Software Engineer at Google, says that “developers of Android apps using WebView no longer have to make any changes to benefit from this protection.”
When Safe Browsing is triggered, the app will present a warning and receive a network error. Apps built for API level 27 and above can customize this behavior with new APIs for Safe Browsing.
