Migrating to androidx.webkit

For static methods:

Old code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O_MR1) {
   WebView.startSafeBrowsing(appContext, callback);
}

New code:

if (WebViewFeature.isFeatureSupported(WebViewFeature.START_SAFE_BROWSING)) {
   WebViewCompat.startSafeBrowsing(appContext, callback);
}

Or, if you are using a non-static method:

Old code:

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.M) {
   myWebView.postVisualStateCallback(requestId, callback);
}

New code:

if (WebViewFeature.isFeatureSupported(WebViewFeature.VISUAL_STATE_CALLBACK)) {
   WebViewCompat.postVisualStateCallback(myWebView, requestId, callback);
}
