App crashes when chooseing activity

I know I could Just manually set this up but I should be able to use a array, but I keep getting a crash, I am thinking it is something simple nut I just cannot find the issue, the crash occurs once a button is pressed :

I can only guess without seeing the logcat, but probably the exception you're getting is an ActivityNotFoundException. In your manifest, your Activities respond to actions whose names start with "android.intent.action", and in code you're initiating actions with names starting with "com.eric.theworks.". I'd recommend you changing actions described in manifest to the "com.eric.theworks." variant, cause using default Android naming for custom actions is not a good thing to do. Hope this solves your problem.

Most probably its the code in your activities rather than the manifest or layouts. Check your logcat logs and the exception that is crashing your app is shown and will give you information what is wrong.
