Protection to install without google play from.

Hi,

Is there any way on Unity to deny install game which had been downloaded from somewhere instead of install via google play?

How can i block installation like that?

Thank you for now!

 

Are you using the Anti-Piracy check? http://docs.unity3d.com/Manual/AndroidMobileAdvanced.html

 

Thanks for reply.

No i dont use it currently. Actually i dont know what is it. i Will research for it.

 

Is there another idea about question?

Thanks.
