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)]
warning

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);
