我正在尝试按照 facebook 开发人员的指南使用 Facebook 3.0 SDK 登录： https://developers.facebook.com/docs/tutorials/androidsdk/3.0/scrumptious/authenticate/
我的问题是，当用户单击登录按钮时，我的 Activity 关闭，Facebook 的进程终止。
这是 Android Studio 的 logcat：
08-20 12:17:40.124 353-353/system_process I/ActivityManager: START u0 {act=SSO_WITH_FALLBACK cmp=com.my.app/com.facebook.LoginActivity (has extras)} from pid 30362

08-20 12:17:45.494 353-12974/system_process I/ActivityManager: Process com.facebook.katana:dash (pid 30233) has died.
对我的问题有什么建议吗？

编辑2： 在模拟器上尝试会出现相同的错误，因为未安装 facebook APK，它会显示一个 webview，要求登录，然后关闭该活动。 我添加了方法跟踪日志记录，MainActivity 中的最后一个调用是 onDestroy...
刚刚找到了这个问题的解决方案。
确保您不使用
android:noHistory="true"
在清单中，相对于 MainActivity（在给定的示例中）。
