Adding an Image

For some reason, my app won't start on my Galaxy S3 testing phone, it always says: "Unfortunately, Crystal Ball has stopped working". I followed all the instructions, but it won't start.

For some reason, I can't figure out how to post the logcat error code, so I'll just type it in:

That was all I could get out of the LogCat before it started to delete the messages. Hope it was needed.
