I'm a bit new to StackOverflow and I was wondering if I could have a bit of input on the following issue: I'm attempting to save a bit of data in a sqlite database but each time I attempt to do so the app force closes and I'm not sure why. I've cleaned the file and there are no issues. (I have no idea what I've done wrong - but something has been programmed incorrectly.)

The problem is here in your onCreate()
@Override
public void onCreate(Bundle savedInstanceState)
{
nameEt = (EditText) findViewById(R.id.nameEdit);
capEt = (EditText) findViewById(R.id.capEdit);
codeEt = (EditText) findViewById(R.id.codeEdit);
timeEt = (TimePicker) findViewById(R.id.timeEdit);
You need to call setContentView() before trying to access your EditTexts and so on. Your Views "live" within your layout (xml file) so they are null until you inflate the layout. Change it to someting like
@Override
public void onCreate(Bundle savedInstanceState)
{
setContentView(R.layout.your_layout); // where your_layout is the name of the xml file with the layout you want to use minus the .xml extention
//this layout must contain all of these views below that you are trying to initialize
nameEt = (EditText) findViewById(R.id.nameEdit);
capEt = (EditText) findViewById(R.id.capEdit);
codeEt = (EditText) findViewById(R.id.codeEdit);
timeEt = (TimePicker) findViewById(R.id.timeEdit);
Edit
Just like the error says, you are trying to cast a TextView to a TimePicker. Here
timeEt = (TimePicker) findViewById(R.id.timeEdit);
(R.id.timeEdit) points to a TextView but here
private TimePicker timeEt;
you declare it as a TimePicker. If you want it to be a TimePicker then change it in your xml
`<TimePicker
android:id="@+id/timeEdit"
style="@style/StyleText"/> `
Also, you have multiple ids in your xml
android:id="@+id/codeText"
might want to change that
Second Edit
03-29 13:23:33.790: E/AndroidRuntime(20744): android.app.SuperNotCalledException: Activity {com.app.gamedemo/com.app.gamedemo.AddEditCountry} did not call through to super.onCreate()
This line in the logcat says it all. You didn't call super.onCreate(). Add the following line as the first line in your onCreate() method
super.onCreate(savedInstanceState);
When reading your logcat, look for where it says Fatal Exception. The next line should say what it is (Null Pointer Exception, Class Cast Exception, etc...) then look for the first line that references your package name and it will tell you where to start looking for the error. Ex. Main.java 57 tells you that whatever the fatal exception was occurs in your Main.java file at line 57. The problem may originally come from somewhere else but this is always a good place to start so you can narrow it down and post relevant code if you need help.
