JavaAndroidKotlinVibrationAndroid Vibration

Java Problem Overview

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

Java Solutions

Solution 1 - Java

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);
}

Note:

Don't forget to include permission in AndroidManifest.xml file:

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

Solution 2 - Java

#Grant Vibration Permission#

Before you start implementing any vibration code, you have to give your application the permission to vibrate:

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

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.

Solution 3 - Java

Update 2017 vibrate(interval) method is deprecated with Android-O(API 8.0)

To support all Android versions use this method.

// Vibrate for 150 milliseconds
private void shakeItBaby() {
    if (Build.VERSION.SDK_INT >= 26) {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE));
    } else {
        ((Vibrator) getSystemService(VIBRATOR_SERVICE)).vibrate(150);
    }
}

Kotlin:

// Vibrate for 150 milliseconds
private fun shakeItBaby(context: Context) {
    if (Build.VERSION.SDK_INT >= 26) {
        (context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(VibrationEffect.createOneShot(150, VibrationEffect.DEFAULT_AMPLITUDE))
    } else {
        (context.getSystemService(VIBRATOR_SERVICE) as Vibrator).vibrate(150)
    }
}

Solution 4 - Java

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

  1. 0 is for delay
  2. 100 says vibrate for 100ms for the first time
  3. next comes delay of 1000ms
  4. 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. :)

Solution 5 - Java

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!

Solution 6 - Java

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 (https://stackoverflow.com/questions/4402740/android-long-click-on-a-button-perform-actions) or button listener, or a clickable object as defined in XML (https://stackoverflow.com/questions/4785544/clickable-image-android):

    public void vibrate(int duration) { Vibrator vibs = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE); vibs.vibrate(duration);
    }

Solution 7 - Java

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"/>

Solution 8 - Java

Vibrating in Patterns/Waves:

import android.os.Vibrator;
...
// Pause for 500ms, vibrate for 500ms, then start again
private static final long[] VIBRATE_PATTERN = { 500, 500 };

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

if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.O) {
    // API 26 and above
    mVibrator.vibrate(VibrationEffect.createWaveform(VIBRATE_PATTERN, 0));
} else {
    // Below API 26
    mVibrator.vibrate(VIBRATE_PATTERN, 0);
}

Plus

The necessary permission in AndroidManifest.xml:

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

Solution 9 - Java

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

should be added inside <manifest> tag and outside <application> tag.

Solution 10 - Java

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:

<button android:layout_height="wrap_content" 
        android:layout_width ="wrap_content" 
        android:onclick      ="longVibrate" 
        android:text         ="VibrateThrice">
</button>

That's the easiest way.

Solution 11 - Java

I use the following utils method:

public static final void vibratePhone(Context context, short vibrateMilliSeconds) {
	Vibrator vibrator = (Vibrator) context.getSystemService(Context.VIBRATOR_SERVICE);
	vibrator.vibrate(vibrateMilliSeconds);
}

Add the following permission to the AndroidManifest file

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

You can use overloaded methods in case if you wish to use different types of vibrations (patterns / indefinite) as suggested above.

Solution 12 - Java

Use this:

import android.os.Vibrator;
     ...
     Vibrator v = (Vibrator) getSystemService(Context.VIBRATOR_SERVICE);
     // Vibrate for 1000 milliseconds
     if (Build.VERSION.SDK_INT >= 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:

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

Solution 13 - Java

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

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