在广播接收器中接收时重新启动片段活动

Question

I have an ongoing activity but once I receive a broadcast from the android.net.conn.CONNECTIVITY_CHANGE I wish to display to the users that there is no internet connection from an already active fragment activity

Container app = (Container) context.getApplicationContext();
app.recreate();

But the above code does not work in the onreceive method in my broadcast intent reciever and cause a can not cast android app to fragment activity Container. How do I fix this?

Try having a "BaseFragmentActivity" that has a broadcast receiver member that does this. And each FragmentActivity in your app should extend it.
