How to use the Broadcast Receiver in android to vibrate the device ?

Question

public class MyBroadcastReceiver extends BroadcastReceiver{
    public void onReceive(Context context , Intent intent){
        Toast.makeText(context, "Your time is up", Toast.LENGTH_LONG).show();
        Vibrator vibrator; 
        // ERROR here (vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
        vibrator.vibrate(2000);
    }
}

While using the Broadcast Receiver to vibrate the device when using an Alarm, there's an error as shown above . What may be the possible reason for an error here ?

What's the error? Maybe you forgot to add the permission in the manifest. — iamtheexp01, Jun 04 '12 at 07:21
Its a syntax error that a ';' is missing but it isn't. and regarding the permission, yes i have added that. — Chetna, Jun 04 '12 at 07:29

Try this

Vibrator v;
v=(Vibrator)context.getSystemService(Context.VIBRATOR_SERVICE);
v.vibrate(3000);

This looks better - the vibrator variable wasn't being initialised. I'd have thought you'd be getting a NullPointerException... – barry Jun 04 '12 at 08:09

did you give permission?

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