将facebook集成为firebase中的身份验证提供者(已经有了一个有效的gmail实现(。以下代码在Unity中运行良好，FB SDK提示输入令牌，手动输入，令牌被传递到firebase，在控制台中可以看到登录，然后加载所需的场景。
当这是建立在安卓设备上时，完全的行为不会发生，正确的Facebook令牌是从新登录或现有登录中收到的，我们输入SignInWithFacebookOnFirebase函数将此帐户登录到firebase中，没有发生任何其他事情，位于("您的令牌是"+aToken(的调试；
我很确定这与异步行为有关，可能不是在等待任务，但我不确定是什么，任何建议都会很棒！

编辑-所以问题与异步无关，而是firebase凭据在移动设备上被持久化的事实。我在下面取消了我所有已经在工作的谷歌认证代码的注释，我们用我们的脸书信誉登录firebase！因此，当A(用户注销和B(用户关闭应用程序(干净或不干净(时，我需要一些方法来清除我们的此令牌。任何帮助都会很棒！

这个问题已经解决了，因为我正在检查这两个脚本中是否存在firebase依赖关系，并且它抛出了一个异常。我使用logcat logs\adb logcat-s Unity ActivityManager PackageManager dalvikvm DEBUG 找到了这个
