public static boolean isFeatureSupported(@NonNull String feature)

Return whether a feature is supported at run-time. This will check whether a feature is supported, depending on the combination of the desired feature, the Android version of device, and the WebView APK on the device.

Note: This method is different from isStartupFeatureSupported and this method only accepts certain features. Please verify that the correct feature checking method is used for a particular feature.

Note: If this method returns false, it is not safe to invoke the methods requiring the desired feature. Furthermore, if this method returns false for a particular feature, any callback guarded by that feature will not be invoked.
