android app publishing in playstore

i want to buy 1 android app source, with regular licence,but i dont understand,when i bought app source, can publish only 1 app in playstore or how I wish
by the app sources, thanks

It doesn’t gives you any guarantee after purchasing from any author

Like if you haven’t got any rights from seller then it’s best to have it in written because later when you are publishing the application code on google play store then you may get in to trouble if he finds out that you are using his code and uploading on play store without his consent or approval.

Thank you
