最近升级support包到28包之后突然出现比较多的这种类型崩溃。之前有看到 #863 报出相似问题，看了下修复的代码的逻辑方式还是单独判断mStateSaved。
public static boolean isStateSaved(FragmentManager fragmentManager) {
if (!(fragmentManager instanceof FragmentManagerImpl))
return false;
try {
FragmentManagerImpl fragmentManagerImpl = (FragmentManagerImpl) fragmentManager;
return fragmentManagerImpl.mStateSaved;
} catch (Exception e) {
e.printStackTrace();
}
return false;
}
private static void hookStateSaved(FragmentManager fragmentManager, Runnable runnable) {
if (!(fragmentManager instanceof FragmentManagerImpl)) return;
FragmentManagerImpl fragmentManagerImpl = (FragmentManagerImpl) fragmentManager;
if (isStateSaved(fragmentManager)) {
fragmentManagerImpl.mStateSaved = false;
compatRunAction(fragmentManagerImpl, runnable);
fragmentManagerImpl.mStateSaved = true;
} else {
runnable.run();
}
}
是否会存在mStopped == true. mStateSaved == false的情况导致出现目前的崩溃
