-
isFeatureSupported(
WebViewFeature feature) → Future< bool> -
Return whether a feature is supported at run-time. On devices running Android version
Build.VERSION_CODES.LOLLIPOPand 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 returnfalse. -
isStartupFeatureSupported(
WebViewFeature startupFeature) → Future< bool> -
Return whether a startup feature is supported at run-time.
On devices running Android version
Build.VERSION_CODES.LOLLIPOPand higher, this will check whether a startup 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 returnfalse.
