Unable to start receiver nullpointerexeption

[Jonovono]

Hey. Can't remember if this will be possible with this but can I execute the java script once the app is closed (bring the app back to the foreground every time a text is received?)

When I run it it receives a text message and displays it on the screen. However if the app is closed and a text is received the phone crashes and the above error is returned (unable to start receiver). However in the logs it looks like the app is still able to get the message data (which is what i want) but then crashes.

Thanks!
