I am making an android app that involves displaying locations on a map. Should I make an API that serves the locations? How would I go about doing that?
You can use Google Map SDK:
Google Map SDK Documents
You need a source of data. Building an api is a good choice. To display markers in a given location you need at least the longitude and latitude.
You can have simple objects with lat/long
and a description to show in a tooltip/infoWindow

I'm building a route recommendation app in Android Studio where the user can see the best route between two destinations on the map. I am using Google Maps APIs for that and I know that it's using Dijkstra's algorithm to determine the route. But I wonder if the API can update the route according to real-time traffic, I didn't find any information about that.
Google Maps is updated constantly – literally, every second of every day!

I am using Google Maps API v2 in my Android application, and I would like to know how could I get an elevation details of a specific route, e.g for a 10km route ahead. I'd like to update this graph on every location change.
I know I can get it like THIS. This however is not possible for me. I have the map area downloaded for an offline use. I just want the API to give me the elevation data from those, without connecting to the internet.
I am doing an app that allows users to get directions from one room to the next room of the same building and require the application to show the user indoor directions. I have tried and tested the Google Maps Intent which opened the Google Maps app and gave directions from one room to the next. I am required to not allow the user to open up an external map app and then receive directions. Instead they must use the Google Map built into my application. I was wondering if it's at all possible to do indoor directions on Google Maps Android API. Would genuinely appreciate any help I get. Thanks!
The Google Maps Android API v2 has options for indoor maps. See https://developers.google.com/maps/documentation/android/ under 'Indoor Maps' for a quick example.
Of course, that doesn't prevent them from using an external app by itself, but it does let you provide them indoor map data in your app.
Well I think you should have to start by using internal sensors to navigate. Add an indoor map of the building so that you would know where you are at in the building.
I want to show a google map of a place with custom markers for different places. I want to be able to edit these markers without updating the app. Best way to do this according to me is using Maps Engine layer in Maps api for android. I have tried searching but haven't gotten an answer.
If there is a better way to do what I am trying to achieve please suggest me that. Let me know if updating/adding markers is not possible without updating the app.
Yes you can pull maps engine data into your app via the API and populate markers on your map view.
Google give some great examples in the API docs # Maps Engine API docs
You could also roll a home brew solution and store your marker data on a server and have your application check for updates each run or daily.

Use Google-Place-Api for this.
There are nice tutorials for how to use this api in android.
