获取异常"IllegalStateException: onSaveInstanceState后不能执行此操作"

我有一个Live Android应用程序，从市场上我收到了以下堆栈跟踪，我不知道为什么它会发生，因为它不是发生在应用程序代码中，而是由应用程序的一些或其他事件引起的(假设)

我没有使用片段，仍然有一个FragmentManager的参考。如果有人能揭示一些隐藏的事实，以避免这类问题:

我认为在这些操作之前调用FragmentActivity.onStateNotSaved()可能是目前最好的选择。

在我的例子中，有相同的错误异常，我把“onBackPressed()”放在一个可运行对象中(你可以使用你的任何视图):

myView.post(new Runnable() {
                    @Override
                    public void run() {
                        onBackPressed()
                    }
                });

我不知道为什么，但它有效!

在屏幕被锁定\blank并且Activity +对话框的实例状态被保存之后，在对话框片段上调用dismiss()也会发生这种情况。要绕过这个调用:

dismissAllowingStateLoss()

实际上，每次我解散一个对话框时，我都不再关心它的状态了，所以这样做是可以的——实际上你并没有失去任何状态。

只需在显示你的片段之前调用super.onPostResume()，或者在调用super.onPostResume()之后在onPostResume()方法中移动你的代码。这就解决了问题!

My use case: I have used listener in fragment to notify activity that some thing happened. I did new fragment commit on callback method. This works perfectly fine on first time. But on orientation change the activity is recreated with saved instance state. In that case fragment is not created again implies that the fragment have the listener which is old destroyed activity. Any way the call back method will get triggered on action. It goes to destroyed activity which cause the issue. The solution is to reset the listener in fragment with current live activity. This solve the problem.
