ファイヤーベースのfacebookログインで認証に失敗しました

Question

firebaseのデモアプリケーションを開発していますが、firebaseのfacebookとgoogleのログインを追加していますので、グーグルはうまく動作しますが、いつでもfacebookを使用してログインしようとしていれば実行時にAuthentication failedすべてのstackOverflowソリューションを試してみましょうが、うまくいかなかったので、誰もこの問題を解決する方法を知っていますか？以下は

私のログインコードです： -

public class SplashScreen extends AppCompatActivity implements GoogleApiClient.OnConnectionFailedListener { 

    //constant values 
    public static final String USER_NAME="com.gaurav.javascripttutorial.username"; 
    public static final String USER_IMAGE="com.gaurav.javascripttutorial.userimage"; 
    public static final String USER_ID="com.gaurav.javascripttutorial.userid"; 

    int RC_SIGN_IN = 1000;

     pref = this.getSharedPreferences("user",0); 
     editor = pref.edit(); 

     dialog = new ProgressDialog(this); 
     dialog.setMessage("Loading, Please wait...."); 

     //Google configuration 
     GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN)

あなたは（read the docs、そうでない場合は）正しく設定すべてを持っていると仮定すると、これはKotlinコードは申し訳ありませんが、（私のために正常に動作しているあなたは、Javaが必要な場合は、ちょうど。作る翻訳）：

マイActivityが伸びるAppCompatActivity：

class ActivityLogin : AppCompatActivity() { 

    private val callbackManager: CallbackManager = CallbackManager.Factory.create() 
    private val mAuth: FirebaseAuth = FirebaseAuth.getInstance() 

    override fun onCreate(savedInstanceState: Bundle?) { 
     super.onCreate(savedInstanceState) 
     setContentView(R.layout.main_splashscreen) 

     loginButton.setReadPermissions("email", "public_profile") 
     loginButton.registerCallback(callbackManager, object : FacebookCallback<LoginResult> { 
      override fun onSuccess(result: LoginResult) { 
       handleFacebookAccessToken(result.accessToken) 
      } 

      override fun onCancel() { 
       Toast.makeText(this@ActivityLogin, "Facebook Authentication canceled.", Toast.LENGTH_SHORT).show() 
      } 

      override fun onError(error: FacebookException?) { 
       Toast.makeText(this@ActivityLogin, "Facebook Authentication failed.", Toast.LENGTH_SHORT).show() 
      } 
     }) 
    } 

    override fun onActivityResult(requestCode: Int, resultCode: Int, data: Intent) { 
     super.onActivityResult(requestCode, resultCode, data) 
     callbackManager.onActivityResult(requestCode, resultCode, data) 
    } 

    private fun handleFacebookAccessToken(token: AccessToken) { 
     val credential = FacebookAuthProvider.getCredential(token.token) 
     mAuth.signInWithCredential(credential) 
       .addOnCompleteListener(this) { task -> 
        if (task.isSuccessful) { 
         val mainIntent = Intent(this@ActivityLogin, ActivityFeed::class.java) 
         startActivity(mainIntent) 
         finish() 
        } else { 
         Toast.makeText(this@ActivityLogin, "Firebase Authentication failed.", Toast.LENGTH_SHORT).show() 
        } 
       } 
    } 
} 

あなたが見ることができるように、あなたの活動のonCreate()中に

FacebookSdk.setApplicationId(getString(R.string.fb_app_id)); 
FacebookSdk.sdkInitialize(getApplicationContext()); 

を呼び出す必要はありません。
