Vibrate Phone | Android Studio | Kotlin

How to vibrate phone programmatically for a specific time?

You can easily implement the phone vibrate programmatically using Android Vibrator API. In this example, we will vibrate the phone for 1000 microseconds i.e. 1 second by clicking a button you can change the duration according to your requirements.

>>Watch For Java

Step 1: Create a new project OR open an existing project

Open AndroidManifest and add VIBRATE permission.
