I'm creating an application for recognizing landmarks. When the image is recognized, the result should fall to onSuccess, but instead comes to onFailure.

The following message is displayed in the Log:

If you have not set up billing, please go to the Firebase Console to set up billing: https://firebase.corp.google.com/u/0/project/_/overview?purchaseBillingPlan= true

If you are specifying a debug API Key override and turning on API Key restrictions, make sure the restrictions are set up correctly.

When I click on the link I see the following page: https://login.corp.google.com/request?s=firebase.corp.google.com:443/uberproxy/&d=https://firebase.corp.google.com/u/0/project/_/overview%3FpurchaseBillingPlan%3Dtrue%26upxsrf%3DAKKYJRc2HD6ROcy9V9DxnYxw-pd8yGnml-oEi37m5hKhkWurWQ:1557057663745&maxAge=1200&authLevel=2000000&keyIds=X-q,k02

What will I need to to do?

ML Kit's landmark detection does not run on the device itself, but uses Google Cloud Vision. For this reason your project needs to be on a paid plan, before you can use landmark detection. The first 1000 calls are free, after which you will be charged for additional calls.
