I need your help.
I want to make an android app project for my final research and it's a campus virtual tour app.
After I found a lot of references, I finally decided to build something similar to this app Yale Virtual Campus Tour (for example)
What kind of open source tools (IDE, frameworks, etc) I can use to build something like that?
PS: I'm not picky with the programming language, you can recommend me any tools as long as it's open source (I'm a student so I don't have much budget).
There's VR feature in that app but I'm not going to add VR. Just a simple tour app and my campus is in a single building, so it doesn't really need gps locator.
My priority is to build it fast and can be done in 3-4 months and the main target is for android devices (don't have to look native).
I avoid using Android studio, because based on my experience it would take more than 4 months to build this app using Android studio.
I really need your recommendation. Sorry for bad English, I'm not a native speaker.
