## Public methods
### isFeatureSupported
Added in [1.1.0](https://developer.android.com/jetpack/androidx/releases/webkit#1.1.0)
```
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 `https://developer.android.com/reference/androidx/webkit/WebViewFeature#isStartupFeatureSupported(android.content.Context,java.lang.String)` 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.
| Parameters |
|---|---|
| `@https://jspecify.dev/docs/api/org/jspecify/annotations/NonNull.html https://developer.android.com/reference/java/lang/String.html feature` | the feature to be checked |
| Returns |
|---|---|
| `boolean` | whether the feature is supported given the current platform SDK and WebView version |
