Are you calling this activity using startActivity(intent)? or are you
explicitly calling the onCreate() from your GolfCaddie activity? If the
latter then it will not work as you are bypassing a lot of activity setup
logic that is needed. Using "DBHelper.this" as the context will not work as
the
Another issue is that even if it was working, the progress dialog would
never show up as you are blocking the GUI thread. You should use an
AsyncTask<> and show the progress dialog in onPreExecute(), do all the db
operations in doInBackground() and dismiss the dialog in onPostExecute().

When I had DBHelper not as an activity then I was getting a different
error for ProgressDialog, stating that the number of parameters for show

You must be passing the DBHelper.this as the Context parameter when it
clearly would not be if DBHelper was not an Activity.

Still newish to Java so trying to get my head around many things here :(
Ok, so I switched the DBHelper class back so that it wasn't an activity.
DBHelper.java now has an error and I can't even build my project.
This is the code that is stopping the compile:
ProgressDialog dialog;

It's generally recommended you learn Java on it's own, outside of Android,
or you're going to run into very silly issues like this.
Thanks,
I understand what you are saying, and I am trying to learn Java as I go
along (granted, not the best way) and do some research on line too.
If I change the context to *this* that still doesn't work and still
shows the error below, except the context it is showing now is:

DBHelper should take the Context object as a parameter in the ctor. Use this
passed context in the call to ProgressDialog.show(). When you instantiate
the DBHelper object in GolfCaddie activity, pass "this" as the parameter in
the ctor. Also make sure you call the DBHelper method to create the d

TreKing / Nadeem / Kostya,
Just wanted to say a big thanks to you all for helping me understand
AsyncTask and about what a context is and the interaction between the UI
thread and AsyncTask threads :)
I got it and I have (at least the start of) my app working the way I
want it to work.
