I am having problems locating the nullpointerexeption that keeps coming up. The log cat does not show a "caused by" tag and that is what is making it difficult to find out what the actual problem is. If anyone could just guide me to finding out what the problem is then that would be great. I have also tried running the debugger and I get the provided error, but I have no clue what to do about it. Below is the error messages that I keep getting, and if need be I will post the code.
Debugger:
