This is a bus tracking app that retrieves the location co-ordinates from firebase and shows is on a map. I set up google maps and Got the api key from the console. It works when I use it in the simulator but when I upload it to the playstore it does not work.
It starts in the MainActivity where the user selects the bus number, from there the user is taken to the maps activity where the location of the bus is shown. the data from the main activity to the maps activity is done using intents.
I am unable to figure out why the map isn't loading when downloaded from the playstore as it works perfectly when used with a simulator or a cable connected device.

I think this is the cause, if so how do I fix it?
Google Maps API Key issue It shows the api as (debug), does it affect the release version of this? if where do I enter the API Key for the release version?
Maps Activity XML XML issue?
