android local broadcast not received from Adapter to service

Question

I have a Expandable List Adapter, which i am instantiating in MainActivity

ExpAdap adap = new ExpAdap(MainActivity.this);

And the constructor of ExpAdap is as below

public void ExpAdap(Context cntext){
    mInflator = LayoutInflater.from(context);
}

I am sending LocalBroadcast, as below

LocalBroadcastManager.getInstance(mInflator.getContext()).sendBroadcast(myIntent);

In my service, I have registered for a Broadcast receiver to receive . But it's not registering.

The same Broadcast receiver received broadcast, when it is sent from From an adapter, which is set to a ListFragment.

What could be the problem?
