I have an android application on which I want to add AR based exit system that will show a safe exit from the building in case of fire. The app shows notification only so, now I want an AR Map on android. Kindly send me your proposal with all the details of libraries, framework, and approach that you will use, and all the requirements you want in order to develop a map as well as mention your charges. The deadline is as soon as possible. Please note that no flutter or react native app is required only android with java.
