No information stored in SQLite Database

I've been working on a Login-Register application and is currently facing some problem. The problem I encountered was no data is stored into my SQLite Database even though I was able to enter information and click on the "sign up" button. And whenever I press on the "Login" button, the application will always show "Unfortunately this application stopped". Anyone know why and can help? I hope to get help soon as I am doing this for my final year project. Million of thanks to all of you.
