Do I need to add an intent-filter when starting a service?

Question

I am following a tutorial to setup a service to start on boot where the last piece of the code is:

Make an entry of this service in AndroidManifest.xml as

<service android:name="MyService">
<intent-filter>
<action
android:name="com.wissen.startatboot.MyService" />
</intent-filter>
</service>

Now start this service in the BroadcastReceiver MyStartupIntentReceiver’s onReceive method as

public void onReceive(Context context, Intent intent) {
    Intent serviceIntent = new Intent();
    serviceIntent.setAction("com.wissen.startatboot.MyService");
    context.startService(serviceIntent);

}

As you see it uses intent-filters and when starts the service adds action. Can I just use

startService(new Intent(this, MyService.class));

What's the advantage of one compared to the other?

Answer 1

Assuming this is all in one application, you can use the latter form (MyService.class).

I'd use the custom action string if you wanted third parties to start this service.
