第一个问题
clasdef 4.4 明明多个dex都设置正常，包括依赖引用 multiDexEnabled true
implementation 'com.android.support:multidex:1.0.1'
并在appcontext里面加上
protected void attachBaseContext(Context base) {
super.attachBaseContext(base);
MultiDex.install(this);
}
并且
依然没有错误，太让我怀疑人生了，于是我打包看了看就一个dex,好吧，我全部删掉，关闭 多个dex好了，ok完美，这个问题是逃避的解决方法，因为其它重新编译的方法都尝试过了。
第二个问题
横屏切换 测试内存不足界面被销毁回来之后崩溃，调用onRestoreInstanceState 和onRestoreInstanceState`
结果打死都不调用onRestoreInstanceState 只调用前者,这个问题就算了，不管了，那么内存不足引发的崩溃问题复现了,

java.lang.IllegalArgumentException: No view found for id 0x7f09009f (cn.qssq666.robot:id/fragment_space_x) for fragment Tab1PosterMenuContainFragment{df83d73 #10 id=0x7f09009f}
网上的方法无非就是使用getChildFragmenManager，我使用childFragmentManager 页面是空白的，我头脑发胀，反复的 调试parent fragment的替换方式为getChildManager或者fragmetn的 fragmentManager或者getActivity().getSuppoertFragmentManager()都不能解决问题,到底应该怎么做，
在我写这篇文章的时候我突然焕然大悟，空白是不是因为 fragment被窝做了某些懒加载等导致的。
final ArrayList> listFragment = new ArrayList();
listFragment.add(Tab1PosterMenuContainFragment.class);
listFragment.add(Tab1PosterMenuContainInvitationFragment.class);
Class fragmentClass = listFragment.get(index);
try{
FragmentUtil.replaceFragment(getActivity(), fragmentClass, R.id.fragment_space_x, false);//todo 空白问题没法解决了。 但是onSaveInstanceState No view found for id for...
}catch (IllegalArgumentException e){
final ArrayList list = new ArrayList();
list.add(new Tab1PosterMenuContainFragment());
list.add(new Tab1PosterMenuContainInvitationFragment());
list.add(new Tab1PosterMenuContainVideoFragment());
BaseLazyLoadFragment fragment = list.get(index);
fragment.setLazyLoadMode(false);
FragmentUtil.replaceChildFragment(PosterFragment.this,getActivity(), fragment,R.id.fragment_space_x,false);
}
那么我就这样写，或者直接使用catch里面的代码应该就可以了。
由于fragment一个嵌套一个嵌套了很多个了，
那么问题太多了。
java.lang.IllegalStateException: Fragment has not been attached yet.
at android.support.v4.app.Fragment.instantiateChildFragmentManager(Fragment.java:2308)
包括vivewpager里面使用getFragmentManger导致滑动不流畅之类的。
改良之后的fragment替换代码
public static void replaceFragment(final Fragment parentFragment, final FragmentActivity activity, final Fragment fragment, final Bundle bundle,
final int containerId, final String tag, final String backStackName,
final boolean addToBackStack, final boolean needAnim) {
Bundle tempBundle = bundle;
if (tempBundle != null) {
fragment.setArguments(tempBundle);
}
FragmentManager supportFragmentManager;
if (parentFragment != null) {
if (!parentFragment.isAdded()) {
Log.e(TAG, "fragment not added");
return;
}
if (parentFragment.getActivity() == null) {
Log.e(TAG, " java.lang.IllegalStateException: Fragment has not been attached yet.");//继续调用也没用 还是会崩溃
return;
}
supportFragmentManager = parentFragment.getChildFragmentManager();
} else {
supportFragmentManager = activity.getSupportFragmentManager();
if (fragment instanceof FragmentOnStartNeedCheckVisible) {
((FragmentOnStartNeedCheckVisible) fragment).setOnStartNeedCheckData(true);
}
}
if (fragment != null && supportFragmentManager != null) {
FragmentTransaction transaction = supportFragmentManager.beginTransaction();
if (needAnim) {
transaction.setCustomAnimations(android.R.anim.slide_in_left, android.R.anim.slide_out_right);
}
if (Build.VERSION.SDK_INT >= Build.VERSION_CODES.JELLY_BEAN_MR1) {
if (activity == null || activity.isDestroyed()) {
Log.e(TAG, "activity is destory! " + Log.getStackTraceString(new Throwable()));
return;
}
}
// transaction.setCustomAnimations(R.animator.fragment_enter_left, R.animator.fragment_exit_left);
Log.i(TAG, "containerId:" + (containerId == CONTAINER_ID_DEFAULT ? R.id.fragment_space : containerId) + "");
transaction.replace(containerId == CONTAINER_ID_DEFAULT ? R.id.fragment_space : containerId, fragment, tag);
if (addToBackStack) {
transaction.addToBackStack(backStackName);
}
transaction.commitAllowingStateLoss();
