Adding Firebase to existing Android app -

i trying add firebase existing android app, i'm having trouble deciding parts of provided google-services.json file should import app. can't override because json file firebase spits out doesn't have info need. know need add? in advance!

edit add sample code: firebase gives me: { "project_info": { "project_number": "a project project number", "firebase_url": "https://my-project.firebaseio.com", "project_id": "a project id", "storage_bucket": "my-project.appspot.com" }, "client": [{ "client_info": { "mobilesdk_app_id": "an id", "android_client_info": { "package_name": "my-package-name" } }, "oauth_client": [ ... ], "api_key": [{ "current_key": "a key" }], "services": { ... } }], "configuration_version": "1" }

and have on project: { "project_info": { "project_id": "a different project id", "project_number": "a different project number" }, "client": [{ "client_info": { "mobilesdk_app_id": "a different id", "client_id": "android:my-package-name", "client_type": 1, "android_client_info": { "package_name": "my-package-name" } }, "oauth_client": [ ... ], "api_key": [], "services": { ... } } ], "client_info": [], "artifact_version": "1" }
