How to make an Android device vibrate?

Question

I wrote an Android application. Now, I want to make the device vibrate when a certain action occurs. How can I do this?

Answer 1

It's too simple, just try:

import android.os.Vibrator;

...

Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);

// Vibrate for 500 milliseconds

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {

    v.vibrate(VibrationEffect.createOneShot(500, VibrationEffect.DEFAULT_AMPLITUDE));

} else {

    //deprecated in API 26 

    v.vibrate(500);

}

Also add permission in AndroidManifest.xml file:

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