I have created an app that initiates a broadcast receiver class that should
auto respond to phone calls with a text message. The receiver is working
however I get the following exception:
*java.lang.IllegalArgumentException: Invalid destinationAddress*
It looks like "incomingNumber" isn't actually getting retrieved. Please
help!!!
