宿主不能显示插件的DialogFragment

[jiashie]

问题详细描述 Detailed description of the problem

参照官方demo1和host，在demo1里新增加一个MyDialogFragment，在host里参照PluginFragmentActivity的方式，能够生成MyDialogFragment对象，但是fragment.show(getSupportFragmentManager(), "testdialog2");时崩溃。

android.view.WindowManager$BadTokenException: Unable to add window -- token null for displayid = 0 is not valid; is your activity running? at android.view.ViewRootImpl.setView(ViewRootImpl.java:931) at android.view.WindowManagerGlobal.addView(WindowManagerGlobal.java:400) at android.view.WindowManagerImpl.addView(WindowManagerImpl.java:129) at android.app.Dialog.show(Dialog.java:471) at android.support.v4.app.DialogFragment.onStart(DialogFragment.java:418)

复现问题步骤 Steps to reproduce the problem

1. demo1里的MyDialogFragment

   public class MyDialogFragment extends DialogFragment {
   public MyDialogFragment() {
   }
   
   @Override
   public View onCreateView(LayoutInflater inflater, ViewGroup container, Bundle savedInstanceState) {
           LayoutInflater pluginInflater = LayoutInflater.from(RePlugin.getPluginContext());
           return pluginInflater.inflate(R.layout.main_fragment, container, false);
   }
   }

2. host里的调用代码

   private void showDialogFragment() {
       boolean isBuiltIn = true;
       String pluginName = isBuiltIn ? "demo1" : "com.qihoo360.replugin.sample.demo1";
       RePlugin.registerHookingClass("com.qihoo360.replugin.sample.demo1.fragment.MyDialogFragment", RePlugin.createComponentName(pluginName, "com.qihoo360.replugin.sample.demo1.fragment.MyDialogFragment"), null);
       //代码使用插件Fragment
       ClassLoader d1ClassLoader = RePlugin.fetchClassLoader(pluginName);//获取插件的ClassLoader
       try {
           DialogFragment fragment = d1ClassLoader.loadClass("com.qihoo360.replugin.sample.demo1.fragment.MyDialogFragment").asSubclass(DialogFragment.class).newInstance();//使用插件的Classloader获取指定Fragment实例
           //getSupportFragmentManager().beginTransaction().add(R.id.container2, fragment).commit();//添加Fragment到UI
           Log.d("showDialog", "fragment=" + fragment);
           fragment.show(getSupportFragmentManager(), "testdialog2");
       } catch (InstantiationException e) {
           e.printStackTrace();
       } catch (IllegalAccessException e) {
           e.printStackTrace();
       } catch (ClassNotFoundException e) {
           e.printStackTrace();
       }
   }

补充：群里的热心网友用同样的代码，生成apk发给我安装后可以正常显示dialogFragment。 诡异的是：卸载这个apk后，再运行之前我自己生成的demo host apk，也同样地可以正常显示了！！！ 甚至连公司实际项目里原先使用Replugin遇到的这个问题也不一样了！（原先是连插件里的view都inflate不了，现在报和上面一样的log)
