For Android training in Allahabad, I don't think there is any good institute/coaching that can provide the best training in the developer or software development field, my suggestion is that they should go to Hyderabad. Hyderabad is the best place for any kind of software training in a very less amount. In Hyderabad, the fee for any programming language like Java, .Net, and Android is about 3000 to 5000 INR.
It is too cheap in comparison to other cities like Lucknow, Delhi, Pune, Bangalore, and Mumbai. If any case you are not able to go to Hyderabad then you can join Spectrum Technologies in Allahabad which is the best in Allahabad.
