Question

此stacktrace已提交给我的项目问题跟踪器。因为你没有引用我的代码，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();

第二个更改是截取onPause onStop和onResume用于活动，如果应用程序处于暂停状态（或任何其他方式），则保持标志。意图不是在暂停状态下调用.commit（）或.commitAllowingStateLoss（）。恢复应用后，您可以调用FragmentManager提交。为我工作:)）

IllegalStateException - 在stacktrace中没有对我的代码的引用
