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.

Get started

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:

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

This approach only applies to Wisej.NET Hybrid Local applications.

• - or -

• Update the Android Manifest:

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

  <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

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:

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);
