Step 1 − Create a new project in Android Studio, go to File ⇒ New Project and fill all required details to create a new project.

Step 2 − Add the following code to res/layout/activity_main.java

<? xml version= "1.0" encoding= "utf-8" ?>
<RelativeLayout xmlns: android = "http://schemas.android.com/apk/res/android"
   xmlns: tools = "http://schemas.android.com/tools"
   android :layout_width= "match_parent"
   android :layout_height= "match_parent"
   android :orientation= "vertical"
   tools :context= ".MainActivity" >
   <TextView
      android :id= "@+id/textView"
      android :layout_width= "match_parent"
      android :layout_height= "wrap_content"
      android :layout_centerInParent= "true"
      android :gravity= "center"
      android :padding= "16dp"
      android :text= "Vibration example"
      android :textAppearance= "@style/Base.TextAppearance.AppCompat.Large" />
</RelativeLayout>

Step 3 − Add the following code to src/MainActivity.java

package app.tutorialspoint.com.sample ;
import android.content.Context ;
import android.os.Build ;
import android.os.Bundle ;
import android.os.VibrationEffect ;
import android.os.Vibrator ;
import android.support.v7.app.AppCompatActivity ;
public class MainActivity extends AppCompatActivity {
   @Override
   protected void onCreate (Bundle savedInstanceState) {
      super .onCreate(savedInstanceState) ;
      setContentView(R.layout. activity_main ) ;
      Vibrator v = (Vibrator) getSystemService(Context. VIBRATOR_SERVICE ) ;
      assert v != null;
      // 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 ) ;
      }
   }
}

Step 4 − Add the following code to androidManifest.xml

<? xml version= "1.0" encoding= "utf-8" ?>
<manifest xmlns: android = "http://schemas.android.com/apk/res/android"
   package= "app.tutorialspoint.com.sample" >
   <uses-permission android :name= "android.permission.VIBRATE" />
   <application
      android :allowBackup= "true"
      android :icon= "@mipmap/ic_launcher"
      android:label= "@string/app_name"
      android:roundIcon= "@mipmap/ic_launcher_round"
      android:supportsRtl= "true"
      android:theme= "@style/AppTheme" >
      <activity android:name= ".MainActivity" >
         <intent-filter>
            <action android:name= "android.intent.action.MAIN" />
            <category android:name= "android.intent.category.LAUNCHER" />
         </intent-filter>
      </activity>
   </application>
</manifest>

Let's try to run your application. I assume you have connected your actual Android Mobile device with your computer. To run the app from android studio, open one of your project's activity files and click Run  icon from the toolbar. Select your mobile device as an option and then check your mobile device.
