Question

I am trying to use a BroadcastReceiver as an inner class to track the network state but I got the exception in the title. What should I do to

Answer 1

e~~I just meet that problem,and I refactor the class NetworkChangeReceiver to an another place

Answer 2

A non-static inner class cannot be registered via the AndroidManifest.xml. You can either:

Register it dynamically as outlined in this thread, and remove the empty constructor.

Or,

Make your inner class static, and register it in the AndroidManifext.xml.

Answer 3

Your

inner Broadcast receiver must be static ( to be registered through Manifest)

OR

Non-static broadcast receiver must be registered and unregistered inside the Parent class

for this.

I was using an Inner broadcast reciver, without registering it within the class. Either make it static and register in Manifest , or Make it non static and register and unregister inside the parent class .

Answer 4

just make your Receiver Class static like:

public [static] class ReceiverClass extends BroadcastReceiver
