Force close when get values from sqlite

It's my first time to dev android, also SQLite. I follow some tutorials to get values from SQLite. This is my code:

Edit:

 public void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        setContentView(R.layout.main);
        myManager = (LocationManager) getSystemService(LOCATION_SERVICE);
        tv = (TextView) findViewById(R.id.test);

    }
public void onLocationChanged(Location location) {
        // TODO Auto-generated method stub

        latitude = ((Double) location.getLatitude()).toString();
        longitude = ((Double) location.getLongitude()).toString();
        date = getDate();
        time = getCurrentTime();

        if (location != null) {
            if (checkInternet()) {

                String s = "";
                s += "\tLatitude:  " + latitude + "\n";
                s += "\tLongitude: " + longitude + "\n";
                s += "\tDate: " + date + "\n";
                s += "\tTime: " + time + "\n";

                tv.setText(s);
                //lookupData();

                }

            } else {
                Toast.makeText(this, "network connection is not available",
                        Toast.LENGTH_SHORT).show();
                keepSQLite();

            }
        }
    }

    public void keepSQLite() {
        try {
            locationDB = openOrCreateDatabase("locationDB", MODE_PRIVATE, null);
            createTable();
            insertTable();
        } catch (SQLiteException se) {
            Log.e(getClass().getSimpleName(),
                    "Could not create or Open the database");
        } finally {
            locationDB.close();
        }

    }

    private void createTable() {

        locationDB.execSQL("CREATE TABLE IF NOT EXISTS " + "ben_logs_boss"
                + " (username VARCHAR, " + " date VARCHAR, " + "time VARCHAR, "
                + " lat VARCHAR, " + " lng VARCHAR);");
    }

    private void insertTable() {
        locationDB.execSQL("INSERT INTO " + "ben_logs_boss" + " Values ("
                + "ben" + "," + getDate() + "," + getDate() + ","
                + getCurrentTime() + "," + latitude + "," + longitude + ");");
        Toast.makeText(this, "insert", Toast.LENGTH_SHORT).show();
    }


    private void lookupData() {
            **String DB_PATH = "/data/data/test.test.test/databases/";
        String DB_NAME = "ben_logs_boss";
        String myPath = DB_PATH + DB_NAME;
        locationDB = SQLiteDatabase.openDatabase(myPath, null,
                SQLiteDatabase.OPEN_READONLY);**
            cursor = locationDB.rawQuery("SELECT lat,lng FROM " + "ben_logs_boss",
                    null);

            if (cursor != null) {
                if (cursor.moveToFirst()) {
                    do {
                        cursor.getString(cursor.getColumnIndex("lat"));
                        cursor.getString(cursor.getColumnIndex("lng"));

                    } while (cursor.moveToNext());
                }
                cursor.close();
                }
                locationDB.close();
            }

When application run until the step that call this method, force close occurred. I don't know why. Anyone can tell me the mistake(s) ? Thank you.

Update Logcat:

When it call lookupData():

i think you are missing your database extension ie(.sqlite)

String DB_NAME = "ben_logs_boss.sqlite";
