Check that you've declared an <activity> tag for the Sec activity in your AndroidManifest.xml.

But posting (or simply reading) the crash stacktrace from logcat would be more instructive.

Without knowing what the error is, it is really hard to guess what the problem is, but usually when this happens, the button (continueButton in your case) could not be found in the layout. So make sure that you have a View with id continue_button in main.xml.
