Android：FirebaseAuth - 来自Facebook

Question

我正在尝试使用firebase为我的应用程序制作Facebook登录方法。我设置了我的Facebook应用程序和sdk。 登录到Facebook工作正常..问题是当Firebase尝试signInWithCredential身份验证失败时。我还没有找到任何有效的解决方案。所以这是我的Logcat：

signInWithCredential:failure
                                                           com.google.firebase.FirebaseException: An internal error has occurred. [ Unsuccessful debug_token response from Facebook:{"error":{"message":"(#100) You must provide an app access token or a user access token that is an owner or developer of the app","type":"OAuthException","code":100,"fbtrace_id":"CnaYlxG66lv"}} ]
                                                               at com.google.android.gms.internal.zzdxm.zzao(Unknown Source)
                                                               at com.google.android.gms.internal.zzdwn.zza(Unknown Source)
                                                               at com.google.android.gms.internal.zzdxx.zzap(Unknown Source)
                                                               at com.google.android.gms.internal.zzdya.onFailure(Unknown Source)
                                                               at com.google.android.gms.internal.zzdxo.onTransact(Unknown Source)
                                                               at android.os.Binder.execTransact(Binder.java:573)

这是我的代码：

• Facebook按钮和CallbackManager ：

  mAuth = FirebaseAuth.getInstance();
  mCurrentUser = mAuth.getCurrentUser();
  mCallbackManager = CallbackManager.Factory.create();
  mFacebook.setOnClickListener(new View.OnClickListener() {
      @Override
      public void onClick(View v) {
          mFacebook.setEnabled(false);
          LoginManager.getInstance().logInWithReadPermissions(SignUp.this, Arrays.asList("email", "public_profile"));
          LoginManager.getInstance().registerCallback(mCallbackManager, new FacebookCallback<LoginResult>() {
              @Override
              public void onSuccess(LoginResult loginResult) {
                  Log.d(TAG, "facebook:onSuccess:" + loginResult);
                  handleFacebookAccessToken(loginResult.getAccessToken());
              }
  
              @Override
              public void onCancel() {
                  Log.d(TAG, "facebook:onCancel");
                  Toast.makeText(SignUp.this, "Facebook Login is Canceled",Toast.LENGTH_LONG).show();
                  // ...
              }
  
              @Override
              public void onError(FacebookException error) {
                  Log.d(TAG, "facebook:onError", error);
                  Toast.makeText(SignUp.this, "Facebook Login    Error",Toast.LENGTH_LONG).show();
                  // ...
              }
          });
      }
  });
  

• OnActivityResult ：

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

• Firebase handleFacebookAccessToken ：

  private void handleFacebookAccessToken(AccessToken token) {
  Log.d(TAG, "handleFacebookAccessToken:" + token);
  
  AuthCredential credential = FacebookAuthProvider.getCredential(token.getToken());
  mAuth.signInWithCredential(credential)
          .addOnCompleteListener(SignUp.this, new OnCompleteListener<AuthResult>() {
              @Override
              public void onComplete(@NonNull Task<AuthResult> task) {
                  if (task.isSuccessful()) {
  
                      Log.d(TAG, "signInWithCredential:success");
                      Toast.makeText(SignUp.this,"Logged in", Toast.LENGTH_LONG).show();
  
                  } else {
                                                  Log.w(TAG, "signInWithCredential:failure", task.getException());
                      Toast.makeText(SignUp.this, "Authentication failed.",
                              Toast.LENGTH_SHORT).show();
                  }
  
                  // ...
              }
          });
  }
  

• Strings.xml ：所有内容都是Facebook登录快速入门的副本

• AndroidManifest ：所有内容都是来自Facebook登录快速入门的副本。

• Project Build.gradle ：

  buildscript {
  
  repositories {
  google()
  jcenter()
  mavenCentral()
  }
  dependencies {
  classpath 'com.android.tools.build:gradle:3.0.1'
  classpath 'com.google.gms:google-services:3.2.0'
  }
  }
  
  allprojects {
  repositories {
  google()
  jcenter()
  mavenCentral()
  maven {
      url "https://maven.google.com" // Google's Maven repository
  }
  }
  }
  
  task clean(type: Delete) {
  delete rootProject.buildDir
  }
  

• Firebase控制台Facebook登录方法：

• Facebook App基本设置：

• Facebook App高级设置：

• 客户端OAuth设置：

• Key Hashes ：

我认为这就是一切，如果还有别的东西指向我，我会更新我的答案，谢谢！

尝试并更新onClick功能中的功能。我测试了下面的方法并登录。我有一个单独的firebase问题（我相信）
