Vibration

Get started​

To access the Vibration functionality, the following platform specific setup is required.

Android​

The VIBRATE permission is required, and must be configured in the Android project. This permission 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.

Vibrate the device​

The vibration functionality can be requested for a set amount of time or the default of 500 milliseconds. The following code example randomly vibrates the device between one and seven seconds.

private void VibrateStartButton_Clicked(object sender, EventArgs e)
{
    int millisecondsToVibrate = Random.Shared.Next(1000, 7000);
    
    Device.Vibration.Vibrate(vibrationLength);
}

private void VibrateStopButton_Clicked(object sender, EventArgs e) =>
    Device.Vibration.Cancel();

Platform differences​

This section describes the platform-specific differences with the vibration API.

iOS / Mac Catalyst​

  • Only vibrates when device is set to "Vibrate on ring".
  • Always vibrates for 500 milliseconds.
  • Not possible to cancel vibration.
