Trying to start a service on boot on Android

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 at a number of links online but none of the code works. Am I forgetting something?

AndroidManifest.xml

<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:name="com.test.RunService"
    android:enabled="true" />

BroadcastReceiver

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");
    }
}
