Hi everybody.
I'm new to android programming and I'm currently trying to build a
basic app that will take some user input and at the press of a button
parse the input using a service and then send it back to the
activity to be printed onto the screen. My problem is that it seems
like the screen is only updated when I click on the text box. Also,
I'm trying to print from the activity by calling an activity function
in the service and none of the is being printed on the screen. Can
anybody take a look at the code and tell me what your think?
Any help would be much appreciated
