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
<application
android:name=".AppContext"
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<Class<? extends Fragment>> listFragment = new ArrayList();
listFragment.add(Tab1PosterMenuContainFragment.class);
listFragment.add(Tab1PosterMenuContainInvitationFragment.class);
Class<? extends Fragment> 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<BaseLazyLoadFragment> 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 <T> 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();
