Hey everyone,

I'm trying to get started with SQLite. My app keeps force closing on this activity:

public class ViewActivity extends Activity {
    private TextView company;
    private BillMeDB dh;
    public void onCreate(Bundle savedInstanceState) {
        company = (TextView) findViewById(R.id.Company1);
        BillMeDB db = new BillMeDB(this);
        long id;
        id = db.insertEntry("Power", "AEP", "item", "2010.9.15", "w2", "2010.9.24", "2011.1.1", 75.77);
        id = db.insertEntry("Cell Phone", "Verizon", "item", "2010.9.15", "w2", "2010.9.24", "2011.1.1", 185.45);
        Cursor c = db.getEntry(1);
        if (c.moveToFirst())
//       Cursor c = BillMeLoad.database.fetchAllEntries();


I can't figure out why though. It blows up(I think) when it starts creating a DB. Here's my DB file - I have no idea where I've gone wrong, but apparently something isn't right. Can someone give me a hand?

My DB File:

                null, null, null, null);
        if (c != null)
        return c;
    public boolean updateEntry(long rowId, String billname, String company, String item,
            String duedate, String remfreq, String remdate, String enddate, double dueamnt) {

Two things come to mind. One is you are doing a lot in onCreate. This runs before the UI is created. Maybe move the database code into a thread, ( and bear in mind that thread will have to create a handler to update the ui like that textview), that way your onCreate finishes and the program starts. Then I'd say maybe put some debug code into the db code, trys catches etc. Possibly printing to a file or even writing debug code to the textview.



really need to know what the line is and what error you are seeing.

Let it blow up and then post the logs here.
