Android App crashes upon creating Sqlite DB : I'm trying to use a database in my android app but when I start the activity that would use the DB helper/ Contract it crashes. I've tried some query validators and I don't seem to find any errors.
The following I use to use my dbhelper but the second line causes the crash.

        DBhelper dbHelper = new DBhelper(this);
        mDatabase = dbHelper.getWritableDatabase();

Code for my dbcontract is:

public final class DBcontract {

    private DBcontract(){}

    public static class DB_table1 implements BaseColumns {
        public static final String TABLE_Name = "Timer_table";
        public static final String COL_1 = "id";
        public static final String COL_2 = "Title";
        public static final String COL_3 = "Startvalue";
        public static final String COL_4 = "Endvalue";
        public static final String COL_5 = "Timer";

    }
}

and the dbhelper is:

    public class DBhelper extends SQLiteOpenHelper {

    public static final int DATABASE_VERSION = 1;
    public static final String DATABASE_NAME = "archeage.db";


    //Create table query
    public static final String CREATE_TABLE =
            ""      + "CREATE TABLE " + TABLE_Name + " ( "
                    + DBcontract.DB_table1.COL_1 + " INTEGER PRIMARY KEY AUTO_INCREMENT, "
                    + DBcontract.DB_table1.COL_2 + " TEXT NOT NULL, "
                    + DBcontract.DB_table1.COL_3 + " INTEGER NOT NULL, "
                    + DBcontract.DB_table1.COL_4 + " INTEGER NOT NULL, "
                    + DBcontract.DB_table1.COL_5 + " INTEGER NOT NULL"
                    + ");";

    //delete table query
    public static final String DELETE_TABLE = "DROP TABLE IF EXISTS " + TABLE_Name;

    public DBhelper(Context context) {
        super(context, DATABASE_NAME, null, DATABASE_VERSION);
    }

    @Override
    public void onCreate(SQLiteDatabase db) {
        db.execSQL(CREATE_TABLE);

    }

    @Override
    public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
        db.execSQL(DELETE_TABLE);
        onCreate(db);
    }
    }
