Answer 1

I think the most significant lines are these two:

com.chris.mydays.UpdateWidgets.onStart(UpdateWidgets.java:50) at android.app.Service.onStartCommand(Service.java:450) at

So I'd open your UpdateWidgets.java file and go to line 50, which should be in a Service in the onStartCommand() method.
