Firebase 인증 SDK초기화 문의

Question

dependencies {
  compile 'com.google.firebase:firebase-admin:4.0.3'
}

FirebaseOptions options = new FirebaseOptions.Builder()
  .setServiceAccount(new FileInputStream("path/to/serviceAccountKey.json"))
  .setDatabaseUrl("https://<DATABASE_NAME>.firebaseio.com/")
  .build();

FirebaseApp.initializeApp(options);

FirebaseAuth.getInstance().createCustomToken(uid).addOnSuccessListener(new com.google.firebase.tasks.OnSuccessListener<String>() {
    @Override
    public void onSuccess(String s) {
       
    }
});

토큰 구하려고 합니다.

제이슨 파일 생성 후

path/to/serviceAccountKe.json 이 부분에 경로를 적으면 실행이 안되네요............. 

아래 에러 문구입니다

 

Error:(64, 21) error: cannot find symbol method setServiceAccount(FileInputStream)

Error:(68, 39) error: incompatible types: FirebaseOptions cannot be converted to Context

Error:Execution failed for task ':app:compileDebugJavaWithJavac'.
