Takes awhile to get good at diagnosing errors in logcat. I've had this issue several times before and was able to spot this as possible culprit to your issue.

{com.lukan.signalsfrommars/com.lukan.signalsfrommars.StoryActivity}; have you declared this activity in your AndroidManifest.xml?

I'd verify that you declared this activity in your android manifest.
