If he takes the job, then this is certainly wise. But it is still most likely a bad idea to take the job. * As an undergrad on summer internships, and in your first few years of professional work, it is better to optimise for learning rather than earning. A project where you work alone with unfamiliar technology at a non-software company won't provide that. He should instead find a software company with a culture of strong mentoring and code reviews. * It's possible to learn Android, iOS or web development over a summer if you have some previous C++ development experience. But learning all three, and designing and building a reasonable quality app on two platforms + a server backend is just not feasible. The end result will be poor, and the client will not realise that this was because of their own unrealistic expectations. As a result, OP may not get a great reference to use after graduating. I mean, if the other alternatives are fast food jobs, then sure. But he needs to manage the expectations of the employer very carefully - maybe proposing a mobile website only, no native or hybrid apps for the first version.
