Android LVL (License Verification Library) for Air

Please forgive all the noobishness of this question. I'm doing my first Android app.

Is this Android LVL necessary? Will it really help keep my paid app from getting pirated on Google Play?

If so, is there an easier way to do it than this: Licensing Adobe AIR applications on Android | Adobe Developer Connection

For instance, is there any reason I wouldn't just go with this: Android LVL (License Verification Library) for Air

I'd love to get this working on my app, but I was really hoping to do it without building my own ANE (as in the Adobe tutorial). I was hoping Adobe could just provide this ANE or build the licensing process into Flash Pro. Is there a reason this isn't done?

Thanks for your help on this.
