Answer 1

You are not allowed to send this broadcast. If applications could send this broadcast then this could cause problems on the device. This is a protected system broadcast.

Please approach your problem in a different way.

Refer: http://developer.android.com/reference/android/net/ConnectivityManager.html

Notice how there are only a few methods that use that action. This implies you cannot send this broadcast.
