isFeatureSupported

open static fun isFeatureSupported(@NonNull feature: String): Boolean

Return whether a feature is supported at run-time. On devices running Android version and higher, 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. If running on a device with a lower API level, this will always return false.

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.
