Android：在onSaveInstanceState之后无法执行此操作

我仍然不清楚处理碎片以及我活动中发生的其他事情 . 以下是堆栈跟踪：

java.lang.RuntimeException: Failure delivering result ResultInfo{who=null, request=2, result=-1, data=Intent { (has extras) }} to activity {com.ghcssoftware.gedstar/com.ghcssoftware.gedstar.GedStar}: java.lang.IllegalStateException: Can not perform this action after onSaveInstanceState

所以这看起来是我在这个函数中调用popBackStack，我在其中一个视图窗格中清理掉任何堆叠的碎片：

// Pop fragments from second pane
    private void popStack() {
        if (mDualPane && mBottomId >= 0) {
            mViewTab.getTabHelper().tabGetFragManager().popBackStack(mBottomId, 
                    FragmentManager.POP_BACK_STACK_INCLUSIVE);
            mBottomId = -1;
        }
    }

主要是我不确定为什么在“onSaveInstanceState之后”调用之后发生了这种情况，或者如果这是真正发生的事情 . 任何可能的解释？ popBackStackImmediate会有所作为吗？

对于它的 Value ，我无法在测试中重新创建环境，因此它只会出现在报告中 .
