Kotlin update for more type safety

Use it as a top level function in some common class of your project such as Utils.kt

// Vibrates the device for 100 milliseconds.
fun vibrateDevice(context: Context) {
    val vibrator = getSystemService(context, Vibrator::class.java)
    vibrator?.let {
        if (Build.VERSION.SDK_INT >= 26) {
            it.vibrate(VibrationEffect.createOneShot(100, VibrationEffect.DEFAULT_AMPLITUDE))
        } else {
            @Suppress("DEPRECATION")
            it.vibrate(100)
        }
    }
}

And then call it anywhere in your code as following:

vibrateDevice(requireContext())

Explanation

Using Vibrator::class.java is more type safe than using String constants.

We check the vibrator for nullability using let { }, because if the vibration is not available for the device, the vibrator will be null.

It's ok to supress deprecation in else clause, because the warning is from newer SDK.

We don't need to ask for permission at runtime for using vibration. But we need to declare it in AndroidManifest.xml as following:

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

Use this   import android os Vibrator                Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE           Vibrate for 1000 milliseconds      if  Build VERSION SDK INT  gt   Build VERSION CODES O                v vibrate VibrationEffect createOneShot 1000 VibrationEffect DEFAULT AMPLITUDE          else         deprecated in API 26              v vibrate 1000            Note   Don t forget to include permission in AndroidManifest xml file    lt uses-permission android name  android permission VIBRATE   gt

You can Vibrate the Device and its work     Vibrator v    Vibrator  context getSystemService Context VIBRATOR SERVICE              v vibrate 100     Permission is necessary but not on runtime permission required   lt uses-permission android name  android permission VIBRATE   gt

lt uses-permission android name  android permission VIBRATE   gt    should be added inside  lt manifest gt  tag and outside  lt application gt  tag

Grant Vibration Permission  Before you start implementing any vibration code  you have to give your application the permission to vibrate    lt uses-permission android name  android permission VIBRATE   gt    Make sure to include this line in your AndroidManifest xml file   Import the Vibration Library  Most IDEs will do this for you  but here is the import statement if yours doesn t    import android os Vibrator    Make sure this in the activity where you want the vibration to occur   How to Vibrate for a Given Time  In most circumstances  you ll be wanting to vibrate the device for a short  predetermined amount of time  You can achieve this by using the vibrate long milliseconds  method  Here is a quick example      Get instance of Vibrator from current Context Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE       Vibrate for 400 milliseconds v vibrate 400     That s it  simple   How to Vibrate Indefinitely  It may be the case that you want the device to continue vibrating indefinitely  For this  we use the vibrate long   pattern  int repeat  method      Get instance of Vibrator from current Context Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE       Start without a delay    Vibrate for 100 milliseconds    Sleep for 1000 milliseconds long   pattern    0  100  1000       The  0  here means to repeat indefinitely     0  is actually the index at which the pattern keeps repeating from  the start     To repeat the pattern from any other point  you could increase the index  e g   1  v vibrate pattern  0     When you re ready to stop the vibration  just call the cancel   method   v cancel      How to use Vibration Patterns  If you want a more bespoke vibration  you can attempt to create your own vibration patterns      Get instance of Vibrator from current Context Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE       Start without a delay    Each element then alternates between vibrate  sleep  vibrate  sleep    long   pattern    0  100  1000  300  200  100  500  200  100       The  -1  here means to vibrate once  as  -1  is out of bounds in the pattern array v vibrate pattern  -1     More Complex Vibrations  There are multiple SDKs that offer a more comprehensive range of haptic feedback  One that I use for special effects is Immersion s Haptic Development Platform for Android   Troubleshooting  If your device won t vibrate  first make sure that it can vibrate      Get instance of Vibrator from current Context Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE       Output yes if can vibrate  no otherwise if  v hasVibrator          Log v  Can Vibrate    YES      else       Log v  Can Vibrate    NO        Secondly  please ensure that you ve given your application the permission to vibrate  Refer back to the first point

Above answer is very correct but I m giving an easy step to do it    private static final long   THREE CYCLES   new long     100  1000  1000   1000  1000  1000       public void longVibrate View v            vibrateMulti THREE CYCLES          private void vibrateMulti long   cycles          NotificationManager notificationManager    NotificationManager  getSystemService NOTIFICATION SERVICE          Notification notification   new Notification           notification vibrate   cycles         notificationManager notify 0  notification         And then in your xml file     lt button android layout height  wrap content           android layout width   wrap content           android onclick        longVibrate           android text           VibrateThrice  gt   lt  button gt    That s the easiest way

I struggled understanding how to do this on my first implementation - make sure you have the following    1  Your device supports vibration  my Samsung tablet did not work so I kept re-checking the code - the original code worked perfectly on my CM Touchpad  2  You have declared  above the application level in your AndroidManifest xml file to give the code permission to run   3  Have imported both of the following in to your MainActivity java with the other imports  import android content Context  import android os Vibrator   4  Call your vibration  discussed extensively in this thread already   - I did it in a separate function and call this in the code at other points - depending on what you want to use to call the vibration you may need an image  Android  long click on a button - gt  perform actions  or button listener  or a clickable object as defined in XML  Clickable image - android     public void vibrate int duration         Vibrator vibs    Vibrator  getSystemService Context VIBRATOR SERVICE       vibs vibrate duration

Vibrate without using permission  If you want to simply vibrate the device once to provide a feedback on a user action  You can use performHapticFeedback   function of a View  This doesn t need the VIBRATE permission to be declared in the manifest   Use the following function as a top level function in some common class like Utils kt of your project          Vibrates the device  Used for providing feedback when the user performs an action      fun vibrate view  View        view performHapticFeedback HapticFeedbackConstants LONG PRESS      And then use it anywhere in your Fragment or Activity as following   vibrate requireView      Simple as that

Above answers are perfect  However I wanted to vibrate my app exactly twice on button click and this small information is missing here  hence posting for future readers like me      We have to follow as mentioned above and the only change will be in the vibrate pattern as below   long   pattern    0  100  1000  300   v vibrate pattern  -1     -1 is important   This will exactly vibrate twice  As we already know   0 is for delay 100 says vibrate for 100ms for the first time next comes delay of 1000ms and post that vibrate again for 300ms   One can go on and on mentioning delay and vibration alternatively  e g  0  100  1000  300  1000  300 for 3 vibrations and so on    but remember  Dave s word use it responsibly      Also note here that the repeat parameter is set to -1 which means the vibration will happen exactly as mentioned in the pattern

Try   import android os Vibrator      Vibrator v    Vibrator  getSystemService Context VIBRATOR SERVICE      Vibrate for 500 milliseconds if  Build VERSION SDK INT  gt   Build VERSION CODES O        v vibrate VibrationEffect createOneShot 500  VibrationEffect DEFAULT AMPLITUDE      else         deprecated in API 26      v vibrate 500       Note   Don t forget to include permission in AndroidManifest xml file      lt uses-permission android name  android permission VIBRATE   gt
