java - Android Google Maps path between 2 markers

Question

I am trying to run the following example to display route directions between two locations on Google Map.

https://www.wingsquare.com/blog/drawing-driving-route-directions-between-two-locations-using-google-directions-in-google-map-android/

However, I keep getting the following error in Android Studio run tab when I click on the map to create two markers:

DownloadTask : { "error_message" : "This API project is not authorized to use this API.", "routes" : [], "status" : "REQUEST_DENIED"}

Also, a toast message shows "No route found".

I have the following APIs enabled in Google Developers Console:

• Maps SDK for Android
• Directions API
• Distance Matrix API
• Geocoding API
• Maps Embed API
• Maps JavaScript API
• Places API

However, the error message doesn't seem to have changed between enabling each of the APIs.

Answer 1

Once i face the same problem. Then i check the google account for map sdk. There i found that my account was not added with some payment options. Direction API requires payment method. And finally check that you put correct api key in google_maps_api.xml
