问题详细描述 Detailed description of the problem

Plugin使用FragmentActivity会导致plugin打包时无法把该Activity替换为PluginFragmentXActivity，提示：
[Warning] --> javassist.NotFoundException: androidx.fragment.app.FragmentActivity

复现问题步骤 Steps to reproduce the problem

1. 把demo1中的MainActivity改为继承FragmentActivity
2. 打包demo1
3. 这导致MainActivity的超类完全没有被替换，最终导致由host打开demo1的MainActivity时R.layout.main索引到错误资源导致崩溃
