A:

You need to create a Database file as shown below:
public class SQLiteDataBaseAdapter extends Activity {

    SQLiteHelper helper;
    SQLiteDatabase db, db1;

    long id, id1, id2;

    public SQLiteDataBaseAdapter(Context context) {
        helper = new SQLiteHelper(context);

    }

    // Inserting Data into the DaTaBase
    public long insertData(String task_name, String contact_name, String contact_number, String description, String remarks,
                           String date, String time, String est_comp_date, String est_comp_time, String act_comp_date, String act_comp_time, String notify_date, String notify_time) {

        db = helper.getWritableDatabase();

        ContentValues contentValues = new ContentValues();

        contentValues.put(SQLiteHelper.TASK_NAME, task_name);
        contentValues.put(SQLiteHelper.CONTACT_NAME, contact_name);
        contentValues.put(SQLiteHelper.CONTACT_NUMBER, contact_number);
        //contentValues.put(SQLiteHelper.CONTACT_EMAIL, contact_email);
        contentValues.put(SQLiteHelper.DESCRIPTION, description);
        contentValues.put(SQLiteHelper.REMARKS, remarks);
        contentValues.put(SQLiteHelper.DATE, date);
        contentValues.put(SQLiteHelper.TIME, time);
        contentValues.put(SQLiteHelper.ESTIMATED_COMPLETION_DATE, est_comp_date);
        contentValues.put(SQLiteHelper.ESTIMATED_COMPLETION_TIME, est_comp_time);
        contentValues.put(SQLiteHelper.ACTUAL_COMPLETION_DATE, act_comp_date);
        contentValues.put(SQLiteHelper.ACTUAL_COMPLETION_TIME, act_comp_time);
        contentValues.put(SQLiteHelper.NOTIFY_DATE, notify_date);
        contentValues.put(SQLiteHelper.NOTIFY_TIME, notify_time);

        id = db.insert(SQLiteHelper.TABLE_NAME, null, contentValues);

        Log.d("PaNa", "The value of Id is " + id);

        db.close();
        return id;
    }

    public Cursor getAllData() {
        db = helper.getWritableDatabase();
        String[] columns = {SQLiteHelper.UID,
                SQLiteHelper.TASK_NAME,
                SQLiteHelper.CONTACT_NAME,
                SQLiteHelper.CONTACT_NUMBER,
                //SQLiteHelper.CONTACT_EMAIL,
                SQLiteHelper.DESCRIPTION,
                SQLiteHelper.REMARKS,
                SQLiteHelper.DATE,
                SQLiteHelper.TIME,
                SQLiteHelper.ESTIMATED_COMPLETION_DATE,
                SQLiteHelper.ESTIMATED_COMPLETION_TIME,
                SQLiteHelper.ACTUAL_COMPLETION_DATE,
                SQLiteHelper.ACTUAL_COMPLETION_TIME,
                SQLiteHelper.NOTIFY_DATE,
                SQLiteHelper.NOTIFY_TIME};
        Cursor cursor = db.query(SQLiteHelper.TABLE_NAME, columns, null, null,
                null, null, null);
        StringBuffer buffer = new StringBuffer();
        while (cursor.moveToNext()) {
            int cid = cursor.getInt(0);
            String taskName = cursor.getString(1);
            String est_comp_time = cursor.getString(6);
            buffer.append(cid + " " + taskName + " " + est_comp_time + "\n");
        }

        if (cursor != null) {
            cursor.moveToFirst();
        }

        return cursor;

    }

    //Obtain a single row
    public Task getTask(String id) {

        Log.d("Pana", "The value of id is " + String.valueOf(id));
        db = helper.getReadableDatabase();

        String[] columns = {SQLiteHelper.UID,
                SQLiteHelper.TASK_NAME, SQLiteHelper.CONTACT_NAME, SQLiteHelper.CONTACT_NUMBER, SQLiteHelper.DESCRIPTION, SQLiteHelper.REMARKS, SQLiteHelper.DATE, SQLiteHelper.TIME, SQLiteHelper.ESTIMATED_COMPLETION_DATE, SQLiteHelper.ESTIMATED_COMPLETION_TIME,

                SQLiteHelper.ACTUAL_COMPLETION_DATE, SQLiteHelper.ACTUAL_COMPLETION_TIME, SQLiteHelper.NOTIFY_DATE, SQLiteHelper.NOTIFY_TIME};

        Cursor cursor = db.query(SQLiteHelper.TABLE_NAME, columns, SQLiteHelper.UID + "= ?",
                new String[]{String.valueOf(id)}, null, null, null, null);

        if (cursor != null)
            cursor.moveToFirst();

        Task task = new Task(cursor.getString(1), cursor.getString(2), cursor.getString(3), cursor.getString(4), cursor.getString(5),
                cursor.getString(6), cursor.getString(7), cursor.getString(8), cursor.getString(9), cursor.getString(10),
                cursor.getString(11), cursor.getString(12), cursor.getString(13));

        cursor.close();

        return task;

    }

}

        }
        onCreate(db);

    }

}

I have shown sample example of creating database in android, how to insert data and how to read data. You need to follow this and modify as per your application. The inner class extends SQLiteOpenHelper and the attributes are accessed from Main Class.
Hope this helps you.
