Ravi,
I think your current code looks pretty good. Please be aware that the
constant NETWORK_STATE_CHANGED_ACTION maps to
android.net.wifi.STATE_CHANGE.
I am running nearly the same code and I receive the
NETWORK_STATE_CHANGED_ACTION event. Please, make sure that the
addNetwork(configuration) is successful. But based on your post it is.
Could you post the catlog of the entents which you are receiving?
