如何解决Facebook登录按钮中的内存泄漏？

我在我的应用程序中使用Facebook SDK v4.25.0进行登录。当我点击登录按钮并打开Facebook登录webview，现在我回来按回到登录，然后再按关闭应用程序。由于登录按钮导致内存泄漏。请帮我弄清楚这一点。提前致谢。如何解决Facebook登录按钮中的内存泄漏？

我使用下面的代码使用Facebook登录功能：

rlFacebook.setOnClickListener(new View.OnClickListener() { 
      @Override 
      public void onClick(View v) { 
       callbackManager = CallbackManager.Factory.create(); 
       loginButton = new LoginButton(mActivity); 

       loginButton.setReadPermissions(Collections.singletonList("public_profile, email")); 
       loginButton.performClick(); 
       loginButton.setPressed(true); 
       loginButton.invalidate(); 
       loginButton.registerCallback(callbackManager, mCallBack); 
       loginButton.setPressed(false); 
       loginButton.invalidate(); 
      } 
     });

这里是我的注销代码的onStop方法：

@Override 
protected void onStop() { 
    super.onStop(); 

    if(callbackManager != null) 
     loginButton.unregisterCallback(callbackManager); 

    if(loginButton != null) 
     loginButton.invalidate(); 
}

以下是我LeakCanary跟踪结果：

你不应该注销mCallback？ –

我有同样的问题，但我决定做一个克隆，因为我无法修复漏洞

XML 
<Button android:id="@+id/facebook_button" 
      android:drawableStart="@drawable/com_facebook_button_icon_white" 
      android:background="@color/com_facebook_blue" 
      android:text=" Continue with Facebook" 
      android:textStyle="bold" 
      android:layout_width="wrap_content" 
      android:layout_height="wrap_content" 
      android:gravity="center" 
      android:layout_gravity="center_horizontal" 
      android:layout_marginBottom="8dp" 
      android:layout_marginEnd="8dp" 
      android:layout_marginStart="8dp" 
      android:layout_marginTop="8dp" />

然后使用LoginManager来处理回调。 登录用户与：

LoginManager.getInstance() 
      .logInWithReadPermissions(this, Arrays.asList("public_profile"));
在 OnClickListener

。 希望它有帮助！ :)
