I've been trying to start a service when a device boots up on android, but I cannot get it to work.

I've looked a number of links online but none of the code is working. Am I forgetting something? This is my code.

Manifest

<receiver   android:name=".StartServiceAtBootReceiver"
  android:enabled="true" 
  android:exported="false"
  android:label="StartServiceAtBootReceiver">
  <intent-filter>
    <action android:name="android.intent.action._BOOT_COMPLETED"/>
   </intent-filter>
</receiver>
<service android:enabled="true" android:name="com.test.RunService"/>

Receiver OnReceive

public void onReceive(Context context, Intent intent)
{
  if("android.intent.action.BOOT_COMPLETED".equals(intent.getAction()))
  {
     Intent serviceLauncher = new Intent(context, RunService.class);
     context.startService(serviceLauncher);
     Log.v("TEST", "Service loaded at start");
  }
}

Thanks,
