How do I store TimePicker Data in my simple record

I've created a simple record keeping application using various resources around the internet. I'm able to successfully store text data - however when I attempt to incorporate a TimePicker I end up crashing my entire app.

Any input on how this can be implemented (as well as any code examples) are greatly appreciated!

in you create table statement define a type

CREATE TABLE ...... dtField date, tmpName Text.....

use following for saving date as text

//sample date format - 2013-03-21 13:12:00
android.text.format.DateFormat.format("yyyy-MM-dd hh:mm:ss", dtDate.getTime())
