How To Vibrate The Android Phone

In this tutorial we learn How to Vibrate a phone in default manner or  in the pattern you want.

What we learn:
Service
Vibrating the Phone

Requires Knowledge:
Basic Android


To vibrate a phone we need following Permission Do not forget to declare this permission in Manifest.

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

We can Vibrate a Phone Using an Activity  , Service and Using Threads.

Using Activity will not be a good Idea because it takes time to vibrate the Phone and an Activity always runs in foreground.

We will implement using Service because  a Service runs in Background.

for we need to have an Object of Class Vibrator, we do not create the Object directly but we get Vibrate System Service.

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

Add    <uses-permission android:name="android.permission.VIBRATE"/>  in Your Manifest

So let's start.

Create a new Android Project  "Vibrate Phone".
and edit the manifest and main.xml file

manifest file

<manifest xmlns:android="http://schemas.android.com/apk/res/android"
    package="com.androidjuncture.vibrate"
    android:versionCode="1"
    android:versionName="1.0" >

    <uses-sdk
        android:minSdkVersion="8"
        android:targetSdkVersion="15" />
    
    <uses-permission android:name="android.permission.VIBRATE"/>

    <application
        android:icon="@drawable/ic_launcher"
        android:label="@string/app_name"
        android:theme="@style/AppTheme" >
        <activity
            android:name=".VibrateMainActivity"
            android:label="@string/title_activity_main" >
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />

                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
        </activity>
        
        <!-- Declare the Vibrate Service -->
        <service android:name=".VibrateService"/>
        
    </application>

</manifest>

main.xml

(to be inflated/used in VibrateMainActivity)

<LinearLayout 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:background="#99C2D6"
    android:orientation="vertical">
    
    

    <TextView
        android:layout_marginTop="140dp"
        android:layout_gravity="center_horizontal"
        android:layout_width="wrap_content"
        android:layout_height="wrap_content"
        android:textSize="20dp"
        android:text="Android Vibrate Service Example" />

    <Button
        android:id="@+id/buttonVibrate"
        android:layout_marginTop="20dp"
        android:layout_width="fill_parent"
        android:layout_height="wrap_content"
        android:text="Vibrate" />
    
</LinearLayout>

When User clicks on Vibrate Button we will start a new Service which will vibrate the phone.

VibrateMainActivity .java

public class VibrateMainActivity extends Activity 
{

     @Override
     public void onCreate(Bundle savedInstanceState)
     {
     super.onCreate(savedInstanceState);
     setContentView(R.layout.main);
    
     Button btnVibrate=(Button)findViewById(R.id.buttonVibrate);
    
    
     // Set on click listener and start vibrate service when clicked on Button Vibrate
    
     btnVibrate.setOnClickListener(new View.OnClickListener() {

public void onClick(View arg0) {
// TODO Auto-generated method stub

// Create a New Intent and start the service
Intent intentVibrate =new Intent(getApplicationContext(),VibrateService.class);
startService(intentVibrate);

}
});
     }

   
}

And The Service Class

Do Not Forget To Declare the Service in Manifest like
<service android:name=".VibrateService"/>

public class VibrateService  extends Service
{

    

           @Override
            public void onStart(Intent intent, int startId) 
           {
                // TODO Auto-generated method stub
                super.onStart(intent, startId);
                
                        
                        
                                    Vibrator v = (Vibrator)getSystemService(Context.VIBRATOR_SERVICE);

                                     // pass the number of millseconds fro which you want to vibrate the phone here we
                                     // have passed 2000 so phone will vibrate for 2 seconds.

                                      v.vibrate(2000);

                                   // If you want to vibrate  in a pattern
                                   //  long pattern[]={0,800,200,1200,300,2000,400,4000};
                                   // 2nd argument is for repetition pass -1 if you do not want to repeat the Vibrate
                                   // v.vibrate(pattern,-1);

                                  Toast.makeText(getApplicationContext(), "Phone is Vibrating", Toast.LENGTH_LONG).show();
                             }

        @Override
        public IBinder onBind(Intent intent) 
        {
            // TODO Auto-generated method stub
            return null;
        }
       
}

Point To Note:

   long pattern[]={0,800,200,1200,300,2000,400,4000}

this is pattern in which we want to Vibrate the Phone
first 0  means silent for 0 milisecond
800 means vibrate for 800 milisecond
200 means  means silent for 200 milisecond
1200  means vibrate for 1200 miliseconds

and So On.
