onActivityResult가 실패했습니다 - Google Auth Firebase

Question

Firebase와 Google 계정으로 내 앱 인증을 시도했습니다. 공식 자습서를 읽고 Google 로그인 버튼을 선택하면 계정 목록이 표시되고 그 중 하나를 선택하여 가져옵니다. onActivityResult 메소드의 메시지를 기록하십시오.

GoogleSignInOptions googleSignInOptions = new 
GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
      .requestIdToken("here is my client id") 
      .requestEmail() 
      .build(); 


mGoogleApiClient = new GoogleApiClient.Builder(this) 
       .enableAutoManage(this, new GoogleApiClient.OnConnectionFailedListener() { 
        @Override 
        public void onConnectionFailed(@NonNull ConnectionResult connectionResult) { 
         Log.d(TAG, "onConnectionFailed: failed"); 
        } 
       }) 
       .addApi(Auth.GOOGLE_SIGN_IN_API, googleSignInOptions) 
       .build(); 


mGoogleSignIn.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View view) { 
       Log.d(TAG, "onClick:"); 
       Intent signInIntent = Auth.GoogleSignInApi.getSignInIntent(mGoogleApiClient); 
       startActivityForResult(signInIntent, RC_SIGN_IN); 
      } 
     }); 

그리고에서 onCreate 방법 밖에

:

@Override 
protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 

    if (requestCode == RC_SIGN_IN) { 
     Log.d(TAG, "onActivityResult: requestCode = " + requestCode); 
     GoogleSignInResult result = Auth.GoogleSignInApi.getSignInResultFromIntent(data); 
     if (result.isSuccess()) { 
      Log.d(TAG, "onActivityResult: successful"); 
      GoogleSignInAccount account = result.getSignInAccount(); 
      firebaseAuthWithGoogle(account); 
     } else { 
      Toast.makeText(getApplicationContext(), "Sign In Failed", Toast.LENGTH_LONG).show(); 
      Log.d(TAG, "onActivityResult: failed"); 
     } 
    } 
} 

private void firebaseAuthWithGoogle(GoogleSignInAccount account) { 
    Log.d(TAG, "firebaseAuthWithGoogle: " + account.getId()); 

    AuthCredential credential = GoogleAuthProvider.getCredential(account.getIdToken(), null); 
    mFirebaseAuth.signInWithCredential(credential).addOnCompleteListener(this, new OnCompleteListener<AuthResult>() { 
     @Override 
     public void onComplete(@NonNull Task<AuthResult> task) { 
      if (task.isSuccessful()) { 
       Log.d(TAG, "onComplete: successful"); 
       FirebaseUser user = mFirebaseAuth.getInstance().getCurrentUser(); 
       Intent intent = new Intent(getApplicationContext(), HomeTabActivity.class); 

       startActivity(intent); 
      } else { 
       // If sign in fails, display a message to the user. 
       Log.d(TAG, "signInWithCredential:failure" + task.getException()); 
       Toast.makeText(getApplicationContext(), "Authentication failed.", 
         Toast.LENGTH_SHORT).show(); 
      } 
     } 
    }); 
}

그 열쇠 조심이

GoogleSignInOptions gso = new GoogleSignInOptions.Builder(GoogleSignInOptions.DEFAULT_SIGN_IN) 
      .requestIdToken("here is my client id") 
      .requestEmail() 
      .build(); 
    mGoogleApiClient = new GoogleApiClient.Builder(this) 
      .enableAutoManage(this, this) 
      .addApi(Auth.GOOGLE_SIGN_IN_API, gso) 
      .build(); 
    GLogin.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 

      startActivityForResult(
        AuthUI.getInstance() 
          .createSignInIntentBuilder() 
          .setIsSmartLockEnabled(false) 
          .setProviders(Collections.singletonList(new AuthUI.IdpConfig.Builder(AuthUI.GOOGLE_PROVIDER).build() 
          )) 
          .build(), 
        RC_SIGN_IN); 




     } 
    }); 

onActivityResult를

protected void onActivityResult(int requestCode, int resultCode, Intent data) { 
    super.onActivityResult(requestCode, resultCode, data); 
    if (requestCode == RC_SIGN_IN) { 
     IdpResponse response = IdpResponse.fromResultIntent(data); 
     if (resultCode == ResultCodes.OK) { 
      Intent in = new Intent(this, YourActivity.class); 
      startActivity(in); 
      finish(); 
      return; 
     } else { 
      // Sign in failed 
      if (response == null) { 
       Log.e("Login","Login canceled by User"); 
       return; 
      } 
      if (response.getErrorCode() == ErrorCodes.NO_NETWORK) { 
       Log.e("Login","No Internet Connection"); 
       return; 
      } 
      if (response.getErrorCode() == ErrorCodes.UNKNOWN_ERROR) { 
       Log.e("Login","Unknown Error"); 
       return; 
      } 
     } 
     Log.e("Login","Unknown sign in response"); 
    } 
} 


@Override 
public void onConnectionFailed(@NonNull ConnectionResult connectionResult) { 
    Toast.makeText(getApplicationContext(), "Connection Failed", Toast.LENGTH_SHORT).show(); 
}
