首先框架不支持startActivityFromFragment...当重写了startActivityFromFragment之后,从含有fragment的activity中进入其他activity,再后退回来的时候,会报nullpointerException,这是由于在框架里面fragmentmanager得到的mContext是proxyActivity的,而fragment又是在pluginActivity中初始化的.后退重建fragment的时候,会试图用proxyActivity的classloader加载fragment,但此时proxyActivity的getClassLoader得到的值是null(mPluginPackage还没初始化)
