[Q] Problem developing app for Android

Hi All,

I am a not experienced developer. All I want to do is make a small app to track information of football on TV. I want to do it through a small DB however I've been struggling a lot with an error I've been trying to discover in the last two weeks but I have not been able.

I have teh following code in the class I create the DB

public class DBAdapter {
public static final String KEY_ROWID = "_id";
public static final String KEY_GDATE = "gdate";
public static final String KEY_GTIME = "gtime";
public static final String KEY_GGAME = "ggame";
public static final String KEY_GCOMPETITION = "gcompetition";
public static final String KEY_GCHANNEL = "gchannel";

private static final String TAG = "DBAdapter";

private static final String DATABASE_NAME = "FonTV";
private static final String DATABASE_TABLE = "games";
private static final int DATABASE_VERSION = 2;

private static final String DATABASE_CREATE =
"create table games (_id integer primary key autoincrement, "
+ "gdate text not null, gtime text not null, ggame text not null" +
"gcompetition text not null, gchannel text not null);";

private final Context context;

private DatabaseHelper DBHelper;
private SQLiteDatabase db;

public DBAdapter(Context ctx)
this.context = ctx;
DBHelper = new DatabaseHelper(context);

private static class DatabaseHelper extends SQLiteOpenHelper
DatabaseHelper(Context context)
super(context, DATABASE_NAME, null, DATABASE_VERSION);

public void onCreate(SQLiteDatabase db)
try {
} catch (SQLException e) {

public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion)
Log.w(TAG, "Upgrading database from version " + oldVersion + " to "
+ newVersion + ", which will destroy all old data");
db.execSQL("DROP TABLE IF EXISTS contacts");

//---opens the database---
public DBAdapter open() throws SQLException
db = DBHelper.getWritableDatabase();
return this;

//---closes the database---
public void close()

//---insert a contact into the database---
public long insertContact(String gdate, String gtime, String ggame, String gcompetition, String gchannel )
ContentValues initialValues = new ContentValues();
initialValues.put(KEY_GDATE, gdate);
initialValues.put(KEY_GTIME, gtime);
initialValues.put(KEY_GGAME, ggame);
initialValues.put(KEY_GCOMPETITION, gcompetition);
initialValues.put(KEY_GCHANNEL, gchannel);

return db.insert(DATABASE_TABLE, null, initialValues);

And the main class where I try to insert data has this:

public class ResultsDBActivity extends Activity {
/** Called when the activity is first created. */
public void onCreate(Bundle savedInstanceState) {

DBAdapter db = new DBAdapter(this);;
long id = db.insertContact("12/may", "08:00", "Leeds vs York", "JUME Cup", "ITV, BBC");
id = db.insertContact("13/may", "09:00", "London vs Bath", "JUME Cup", "ITV, BBC2");

However when I try to run it, the debugger shows and error that says:

E/Database(330): android.database.sqlite.SQLiteException: no such table: games: , while compiling: INSERT INTO games(gchannel, ggame, gtime, gdate, gcompetition) VALUES(?, ?, ?, ?, ?);

Iíve trying to change parameters and many things but I havenít found where the problem is. Can someone help me please?
