无法添加窗口 - 令牌android.os.BinderProxy无效;在您的活动运行？ [英] Unable to add window -- token android.os.BinderProxy is not valid; is your activity running?
问题描述
我尝试连接到Facebook throught Facebook的API，我按照这个例子：<一href="https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple">https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple
I try to connect to Facebook throught Facebook API, I follow this example: https://github.com/facebook/facebook-android-sdk/tree/master/examples/simple
一切正常，但是当我尝试编辑一些code，我的意思是我要显示该对话框后消息后登录成功，这样的：
Everything is ok, but when I try to edit some code, I mean I want to display the dialog post message after the login is successful like this:
public void onAuthSucceed() {
mText.setText("You have logged in! ");
//This is the code to call the post message dialog.
mFacebook.dialog(Example.this, "feed",new SampleDialogListener());
}
我收到了logcat的这个错误：
I receive this error in the logcat:

你知道吗？
Any idea?
推荐答案
这可以当你表示一个上下文不再存在的对话框出现。常见的情况 - 如果显示对话框操作是一种异步操作之后，并在操作过程中原来的活动（即是你的对话框的父）被破坏。对于一个很好的说明，请参阅此博客文章和评论：
This can occur when you are showing the dialog for a context that no longer exists. A common case - if the 'show dialog' operation is after an asynchronous operation, and during that operation the original activity (that is to be the parent of your dialog) is destroyed. For a good description, see this blog post and comments:
<一个href="http://dimitar.me/android-displaying-dialogs-from-background-threads/">http://dimitar.me/android-displaying-dialogs-from-background-threads/
从上面的堆栈跟踪，似乎Facebook的库旋转关闭身份验证操作异步，和你有一个处理程序 - 回调机制（的onComplete叫上监听器），可以很容易地创建这种情况下
From the stack trace above, it appears that the facebook library spins off the auth operation asynchronously, and you have a Handler - Callback mechanism (onComplete called on a listener) that could easily create this scenario.
当我已经看到了这个报道，我的应用程序，它的pretty的珍稀匹配的博客文章的经验。出事了该活动/它的AsyncTask的工作中被摧毁。我不知道你的修改会如何导致每次都在，但也许你所引用的活动为背景的，就是始终由您code执行时破坏了对话？
When I've seen this reported in my app, its pretty rare and matches the experience in the blog post. Something went wrong for the activity/it was destroyed during the work of the the AsyncTask. I don't know how your modification could result in this every time, but perhaps you are referencing an Activity as the context for the dialog that is always destroyed by the time your code executes?
此外，虽然我不知道这是否是说，如果你的活动正在运行，看到这个答案，这样做的一个方法的最佳方式：
Also, while I'm not sure if this is the best way to tell if your activity is running, see this answer for one method of doing so:
