Hello Commonsware community,
I want to build an application in which the user will have to answer a few questions, and the app will fetch in the database for the best car he/she can buy.
I think it’s something similar to a recommendation system.
Um, your question does not really have much to do with Android.
Beyond that, your question is very unclear:
We do not know what the questions are
We do not know how the questions tie to the database
We do not know what sort of “algorithm” you are seeking
