android - IllegalStateException - 堆栈跟踪中没有对我的代码的引用

Question

此堆栈跟踪已提交到我的项目问题跟踪器。由于您没有对我的代码的引用，所以有人知道如何修复它吗？我正在使用支持库 v19.0.1，如果需要，我可以提供有关设备/平台的更多详细信息

Answer 1

我做的第一个改变是

 getSupportFragmentManager().beginTransaction()
.add(R.id.container,new CatListFragment(null)).commitAllowingStateLoss();

第二个变化是拦截 Activity 的 onPause onStop 和 onResume，如果应用程序处于暂停状态(或任何其他方式)，则维护一个标志。目的不是在暂停状态下调用 .commit() 或 .commitAllowingStateLoss()。恢复应用程序后，您可以调用 FragmentManager 提交。为我工作:)
