# Haptic Feedback

Haptic feedback is generally manifested by a gentle vibration sensation provided by the device to give a response to the user. Some examples of haptic feedback are when a user types on a virtual keyboard or when they play a game where the player's character has an encounter with an enemy character.

### Android

The `Vibrate` permission is required and must be configured in the Android project. This can be added in the following ways:

* Add the assembly-based permission:

  Open the *Platforms/Android/MainApplication.cs* file and add the following assembly attributes after `using` directives:

  ```csharp
  [assembly: UsesPermission(Android.Manifest.Permission.Vibrate)]
  ```

{% hint style="warning" %}
This approach only applies to Wisej.NET Hybrid Local applications.
{% endhint %}

* \- or -
* Update the Android Manifest:

  Open the *Platforms/Android/AndroidManifest.xml* file and add the following in the `manifest` node:

  ```xml
  <uses-permission android:name="android.permission.VIBRATE" />
  ```

  \- or -
* Update the Android Manifest in the manifest editor:

  In Visual Studio double-click on the *Platforms/Android/AndroidManifest.xml* file to open the Android manifest editor. Then, under **Required permissions** check the **VIBRATE** permission. This will automatically update the *AndroidManifest.xml* file.

## Use haptic feedback <a href="#use-haptic-feedback" id="use-haptic-feedback"></a>

The haptic feedback functionality is performed in two modes: a short **Click** or a **LongPress**. The following code example initiates a `Click` or `LongPress` haptic feedback response to the user based on which **Button** they click:

```csharp
private void HapticShortButton_Clicked(object sender, EventArgs e) =>
    Device.HapticFeedback.Perform(HapticFeedbackType.Click);

private void HapticLongButton_Clicked(object sender, EventArgs e) =>
    Device.HapticFeedback.Perform(HapticFeedbackType.LongPress);
```
