我认为生命周期状态可以帮助防止这种崩溃从Android支持库v26.1.0开始，你可以有以下检查:

if (getLifecycle().getCurrentState().isAtLeast(Lifecycle.State.STARTED)){
  // Do fragment's transaction commit
}

或者你可以试试:

Fragment.isStateSaved()

更多信息请点击这里 https://developer.android.com/reference/android/support/v4/app/Fragment.html isStateSaved ()

我对这个问题的解决方案是

在片段中添加方法:

@Override
public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
    ...
    guideMapFragment = (SupportMapFragment)a.getSupportFragmentManager().findFragmentById(R.id.guideMap);
    guideMap = guideMapFragment.getMap();
    ...
}

@Override
public void onDestroyView() {
    SherlockFragmentActivity a = getSherlockActivity();
    if (a != null && guideMapFragment != null) {
        try {
            Log.i(LOGTAG, "Removing map fragment");
            a.getSupportFragmentManager().beginTransaction().remove(guideMapFragment).commit();
            guideMapFragment = null;
        } catch(IllegalStateException e) {
            Log.i(LOGTAG, "IllegalStateException on exit");
        }
    }
    super.onDestroyView();
}

可能很糟糕，但找不到更好的了。

I noticed something very interesting. I have in my app the option to open the phone's gallery and the device asks what app to use, there I click on the gray area away from the dialog and saw this issue. I noticed how my activity goes from onPause, onSaveInstanceState back to onResume, it doesn't happen to visit onCreateView. I am doing transactions at onResume. So what I ended up doing is setting a flag being negated onPause, but being true onCreateView. if the flag is true onResume then do onCommit, otherwise commitAllowingStateLoss. I could go on and waste so much time but I wanted to check the lifecycle. I have a device which is sdkversion 23, and I don't get this issue, but I have another one which is 21, and there I see it.

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!

读 http://chris-alexander.co.uk/on-engineering/dev/android-fragments-within-fragments/

篇文章。 fragment. isresume()检查帮助我在onDestroyView w/o使用onSaveInstanceState方法。

我有这个问题。但是我认为这个问题与commit和commitAllowStateLoss无关。

下面的堆栈跟踪和异常消息是关于commit()的。

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(FragmentManager.java:1341)
at android.support.v4.app.FragmentManagerImpl.enqueueAction(FragmentManager.java:1352)
at android.support.v4.app.BackStackRecord.commitInternal(BackStackRecord.java:595)
at android.support.v4.app.BackStackRecord.commit(BackStackRecord.java:574)

但是这个异常是由onBackPressed()引起的

java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState
at android.support.v4.app.FragmentManagerImpl.checkStateLoss(Unknown Source)
at android.support.v4.app.FragmentManagerImpl.popBackStackImmediate(Unknown Source)
at android.support.v4.app.FragmentActivity.onBackPressed(Unknown Source)

它们都是由checkStateLoss()引起的

private void checkStateLoss() {
    if (mStateSaved) {
        throw new IllegalStateException(
                "Can not perform this action after onSaveInstanceState");
    }
    if (mNoTransactionsBecause != null) {
        throw new IllegalStateException(
                "Can not perform this action inside of " + mNoTransactionsBecause);
    }

mStateSaved在onSaveInstanceState之后为真。

这个问题很少发生。我从来没有遇到过这个问题。我不能再出现这个问题。

我找到了25517号

它可能在下列情况下发生

Back键在onSaveInstanceState之后，但在新活动开始之前被调用。 在代码中使用onStop()

我不确定问题的根源是什么。 所以我用了一个丑陋的方法。

@Override
public void onBackPressed() {

    try{
        super.onBackPressed();
    }catch (IllegalStateException e){
        // can output some information here
        finish();
    }
}
