- strings.xml 과 google-services.json 에 아래 내용을 추가

Eclipse Project > res > values > strings.xml 을 열어, 아래 내용을 추가.

    <string name="default_web_client_id" translatable="false"></string>

    <string name="firebase_database_url" translatable="false"></string>
    <string name="gcm_defaultSenderId" translatable="false"></string>
    <string name="google_api_key" translatable="false"></string>
    <string name="google_app_id" translatable="false"></string>
    <string name="google_storage_bucket" translatable="false"></string>

- Firebase 에서 google-services.json 파일을 다운로드 받아 아래 내용을 추가

(Firebase 로그인후, 앱을 선택한 다음, 기어아이콘.Project Setting 를 누르면 다운로드 받을 수 있다.)

  - 왼쪽이 strings.xml 파일의 name 이고 오른쪽이 google-services.json 파일의 항목을 의미한다.

  * default_web_client_id : client -> oauth_client -> client_id

  * firebase_database_url : project_info -> firebase_url

  * ​gcm_defaultSenderId : project_info -> project_number

  * ​google_api_key : client -> api_key -> current_key

  * ​google_app_id : client -> client_info -> mobilesdk_app_id

  * ​google_storage_bucket : project_info -> storage_bucket
