Are you using the following permissions?
<uses-permission
android:name="android.permission.ACCESS_NETWORK_STATE"/>
<uses-permission
android:name="android.permission.CHANGE_NETWORK_STATE"/>
<uses-permission
android:name="android.permission.ACCESS_WIFI_STATE"/>
<uses-permission
android:name="android.permission.CHANGE_CHANGE_STATE"/>
How do u setup your broadcast receiver?
Write a method:
private void registerForWifiBroadcasts() {
IntentFilter intentFilter = new IntentFilter();
intentFilter.addAction
(WifiManager.NETWORK_STATE_CHANGED_ACTION);
intentFilter.addAction
(WifiManager.SUPPLICANT_CONNECTION_CHANGE_ACTION);
intentFilter.addAction(WifiManager.WIFI_STATE_CHANGED_ACTION);
intentFilter.addAction
(WifiManager.SUPPLICANT_STATE_CHANGED_ACTION);
mContext.registerReceiver(this, intentFilter);
}
or do this in the Manifest file.
With doing this you should be able to get the state change intent.
