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 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>
(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.
{
@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);
}
});
}
}
<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;
}
}
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.

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.
