android - 第二次登录时facebook unity sdk 6.0崩溃应用程序

Question

使用 facebook unity sdk 6.0 创建了一个简单的应用程序。

在启动函数中调用 init facebook。

有一个按钮调用登录，登录回调只是输出字符串。

在装有 android 4.4.2 的 Samsung galaxy s5 上运行。

问题(100% 可重复):

 1. First time click login button, get the facebook login screen.
 2. Click exit button, back to app.
 3. Click login button again, app crashed.

Answer 1

在我的另一个帐户“Helath”上提供了一个更永久的解决方案:

http://answers.unity3d.com/questions/743523/facebook-sdk-cancelled-login-crash.html

公平点，这是我在其他网站上发表的帖子:

如果状态是“登录失败”和“已关闭”，他们基本上忘记了刷新 session 。

如果你愿意，你可以将facebook sdk 导入eclipse 并更改FBLogin.Java 的第63 行

if (SessionState.CLOSED.equals(session.getState())) {
            session = new Builder(FB.getUnityActivity()).setApplicationId(session.getApplicationId()).build();
            Session.setActiveSession(session);
        }

到

   if (SessionState.CLOSED.equals(session.getState()) || SessionState.CLOSED_LOGIN_FAILED.equals(session.getState())) {
                session = new Builder(FB.getUnityActivity()).setApplicationId(session.getApplicationId()).build();
                Session.setActiveSession(session);
            }

然后将项目导出为 jar，只包含类文件，作为 plugins/Android/facebook/bin 文件夹中的 classes.jar。

编辑:如果我上传我正在使用的 classes.jar 可能会更容易...在这里下载:http://speedy.sh/QPgUp/classes.jar并将其放入 Plugins/Android/facebook/bin 文件夹中。

编辑 2:如果您仍然遇到此问题，Facebook 似乎已于 2014 年 10 月 20 日发布了他们的修复程序。因此更新到他们最新的 sdk 现在可以解决这个问题!
