java - Unable to insert data in Sqlite Database android

Following code is used to insert data in the database.

When application is launched, following code is executed.

After RecentDBManager is executed, when I PULL database from emulator memory, it shows no record in FavoriteScrip table.

When I logged InsertStmt in setData method, it works fine. It shows

insert into FavoriteScrip(sym,cmp,chg) values ('value1','value2','value3')

but it is not getting inserted in table...

In main class

 rdbM = new RecentDBManager(CompanyView.this);
                        try {
                            if (!rdbM.checkDataBase()) {
                                rdbM.createDataBase();
                            }
                            rdbM.openDB();
                            rdbM.setData("value1");
                            rdbM.closeDB();

                        } catch (Exception e) {
                            throw new Error("ERROR in DB Access"+ e.toString());
                    }

RecentDBManager class

    public class RecentDBManager {
    private DatabaseHelper dataHelper;
    private SQLiteDatabase mDb;
    private Context ctx;
    private String DATABASE_PATH = "/data/data/com.mypackage/databases/";
    private static String DATABASE_NAME = "ScripMasterDB";
    private static String TABLE_NAME = "FavoriteScrip";
        private String InsertStmt;
    private static final int DATABASE_VERSION = 1;
    private Cursor cur;

    RecentDBManager(Context ctx) {
        this.ctx = ctx;
        dataHelper = new DatabaseHelper(ctx);
    }

    private static class DatabaseHelper extends SQLiteOpenHelper {
        Context myContext = null;

        public DatabaseHelper(Context context) {
            super(context, DATABASE_NAME, null, DATABASE_VERSION);
            this.myContext = context;
        }

        @Override
        public void onCreate(SQLiteDatabase db) {
        }

        @Override
        public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
            Log.w("DBHelper", "Upgrading database from version " + oldVersion
                    + " to " + newVersion + ", which will destroy all old data");
            onCreate(db);
        }
    }

    public boolean checkDataBase() {
        String myPath = DATABASE_PATH + DATABASE_NAME;
        File f = new File(myPath);
        return f.exists();
    }

    public void createDataBase() {
        openDB();
        try {
            OutputStream myOutput = new FileOutputStream(DATABASE_PATH+ DATABASE_NAME);

            if (mDb.isOpen())
                mDb.close();
            myOutput.flush();
            myOutput.close();

        } catch (Exception e) {
            throw new Error("RecentDbManager Exception - " + e.getMessage());
        }
    }

    public RecentDBManager openDB() throws SQLException {
        mDb = dataHelper.getWritableDatabase();
        return this;
    }

    public void setData(String value1, String value2, String value3) {
                ContentValues cv = new ContentValues();
cv.put("sym", value1);
cv.put("dt_tm", "datetime()");
mDb.insert(TABLE_NAME, null, cv);

        } catch (SQLiteException e) {
            throw new Error("RecentDbManager Exception in inserting data"
                    + e.getMessage());
        }
    }

    public void closeDB() {
        try {
            mDb.close();
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
}

EDIT

I have one column which contains current datetime.

So query is of the form "insert into " + TABLE_NAME+ " (sym,dt_tm) values ('" + value1 + "',datetime())"

I tried

    ContentValues cv = new ContentValues();
cv.put("sym", value1);
cv.put("dt_tm", "datetime()");
mDb.insert(TABLE_NAME, null, cv);

value1 column is getting inserted into table but not datetime. What can be the problem?

Final edit

DONE... I used following :

                Calendar date1 = Calendar.getInstance();
                    SimpleDateFormat dateformatter = new SimpleDateFormat(
                            "dd/MM/yyyy HH:mm:ss");

                    String currentdate = dateformatter.format(date1
                            .getTime());

and passed currentdate as second parameter.

THNX ALL !!!!

ANY HELP WILL BE LIFE-SAVER !!!

try

@Override
public void onCreate(SQLiteDatabase db) {
    db.execSQL(Create table Memo (ID INTEGER PRIMARY KEY AUTOINCREMENT, sym TEXT, cmp TEXT, cng TEXT);
}

.

public void setData(String value1, String value2, String value3) {

            ContentValues cv = new ContentValues();
            cv.put("sym", value1);
            cv.put("cmp", value2);
            cv.put("cng", value3);

            mDb.insert(TABLE_NAME, null, cv);
    }
