I have a class StartupReceiver:

public class StartupReceiver extends BroadcastReceiver {

@Override
public void onReceive(Context context, Intent intent) {
    Intent service = new Intent(context, ARMRService.class);
    context.startService(service);
}

and it is declared in my Manifest.xml as

<receiver android:name=".StartupReceiver">  
    <intent-filter>  
        <action android:name="android.intent.action.BOOT_COMPLETED" />  
    </intent-filter>  
</receiver>

and I have given the correct permission:

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

Why is this not working???
