更改Facebook密码后,Facebook客户端崩溃了Facebook SSO登录对话框

Question

我遇到了使用SSO登录facebook的崩溃.我在任何类似的论坛都找不到任何报告.

当我们在Facebook网站上更改用户密码时,在大约15秒内,android facebook客户端将通过通知栏通知用户facebook身份验证失败.如果用户做出反应并登录,我们的应用程序SSO将毫无问题地获取新令牌.

如果用户更改密码,在用户对Facebook应用程序通知做出反应并使用新密码登录之前启动我们的应用程序facebook请求(如下载朋友列表),我们会收到SSO崩溃,这会错误地通知我们的应用程序用户取消登录.

不知何故,facebook应用程序登录对话框(蓝色对话框)和SSO登录对话框(白色对话框)无法共存.如果它们同时打开,SSO启动了Facebook客户端崩溃的实例,但有以下异常:

另一个提示是,在facebook应用程序中有一个窗口泄露非致命异常:Activity com.facebook.katana.ProxyAuth泄漏窗口com.android.internal.policy.impl.PhoneWindow$DecorView@406eecf0 that was originally added here 有没有人遇到过类似的崩溃？我真的很困惑,没有人提到那些崩溃,就谷歌所能找到的那样.我在实现这个时遵循了hackbook示例.我真的不知道可能导致它的原因.

Answer 1

可能与密码更改无关,但删除:

android:launchMode =来自AndroidManifest.xml的"singleInstance"

为我解决了一个类似的错误(com.facebook.katana/com.facebook.katana.ProxyAuth中也有java.lang.NullPointerException)
