join tables sqlite android

I have two tables: user and balance. User DAO:

public class NewUserDAO {
    public static final String TAG = "NewUserDAO";
    public static final String TABLE_NEWUSER = "newUser";
    //database fields
    private SQLiteDatabase mDataBase;
    private DatabaseHandler mDbHelper;
    private Context mContext;
    private String [] mAllColumns = {
            DatabaseHandler.COLUMN_NEWUSER_ID,
            DatabaseHandler.COLUMN_NEWUSER_NAME, DatabaseHandler.COLUMN_NEW_USER_PASSWORD,
            DatabaseHandler.COLUMN_NEW_USER_AGE };

    public NewUserDAO(Context context){
        this.mContext = context;
        mDbHelper = new DatabaseHandler(context);
        try{
            open();
        } catch (SQLException e){
            Log.e(TAG,"SQLexception on opening database" + e.getMessage());
            e.printStackTrace();
        }
    }
    public void open() throws SQLException{
        mDataBase = mDbHelper.getWritableDatabase();
    }
    public void close(){
        mDbHelper.close();
    }
    public void createNewUser(NewUserTable newUserTable){
        ContentValues values = new ContentValues();
        values.put(DatabaseHandler.COLUMN_NEWUSER_NAME,newUserTable.getName());
        values.put(DatabaseHandler.COLUMN_NEW_USER_PASSWORD, newUserTable.getPassword());
        values.put(DatabaseHandler.COLUMN_NEW_USER_AGE, newUserTable.getAge());
        mDataBase.insert(TABLE_NEWUSER, null, values);
        mDataBase.close();
    }

} balance DAO:

public class BalanceDAO {
public static final String TAG = "BalanceDAO";
public static final String TABLE_BALANCE = "balanceOfUser";
private Context mContext;

//Database fields
private SQLiteDatabase mDatabase;
private DatabaseHandler mDhelper;
private String[] mAllColumns = {
        DatabaseHandler.COLUMN_BALANCE_ID,
        DatabaseHandler.COLUMN_BALANCE_DOLLARBALANCE,
        DatabaseHandler.COLUMN_BALANCE_RUBBALANCE,
        DatabaseHandler.COLUMN_BALANCE_NEW_USER_ID
};
public BalanceDAO (Context context){
    mDhelper = new DatabaseHandler(context);
    this.mContext = context;
    try{
        open();
    }
    catch (SQLException e){
        Log.e(TAG, "SQLException on openning database" + e.getMessage());
        e.printStackTrace();
    }
}
public void open() throws SQLException {
    mDatabase = mDhelper.getWritableDatabase();
}
public void close(){
    mDhelper.close();
}
public void createBalance (BalanceTable balanceTable){
    ContentValues values = new ContentValues();
    values.put(DatabaseHandler.COLUMN_BALANCE_DOLLARBALANCE,balanceTable.getDollarBalance());
    values.put(DatabaseHandler.COLUMN_BALANCE_RUBBALANCE,balanceTable.getRubBalance());
    mDatabase.insert(TABLE_BALANCE, null, values);
    mDatabase.close();
}

} And SQLiteOpenHelper class:

public class DatabaseHandler extends SQLiteOpenHelper {

//COLUMNS OF THE NEW USER TABLE public static final String TABLE_NEWUSER = "newUser"; public static final String COLUMN_NEWUSER_ID = "id"; public static final String COLUMN_NEWUSER_NAME = "name"; public static final String COLUMN_NEW_USER_PASSWORD = "password"; public static final String COLUMN_NEW_USER_AGE = "age";

//COLUMNS OF THE BALANCE TABLE
public static final String COLUMN_BALANCE_ID = "id";
public static final String TABLE_BALANCE = "balanceOfUser";
public static final String COLUMN_BALANCE_DOLLARBALANCE = "dollarBalance";
public static final String COLUMN_BALANCE_RUBBALANCE = "rubBalance";
public static final String COLUMN_BALANCE_NEW_USER_ID = "newUserId";

private static final String DATABASE_NAME = "webStore";
private static final int DATABASE_VERSION = 1;


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

@Override
public void onOpen(SQLiteDatabase db) {
    super.onOpen(db);
    if (!db.isReadOnly()) {
        // Enable foreign key constraints
        db.execSQL("PRAGMA foreign_keys=ON;");
    }
}

@Override
public void onCreate(SQLiteDatabase db) {
    String SQL_CREATE_NEWUSER = "CREATE TABLE " + TABLE_NEWUSER + "("
            + COLUMN_NEWUSER_ID + " INTEGER PRIMARY KEY autoincrement,"
            + COLUMN_NEWUSER_NAME + " TEXT not null,"
            + COLUMN_NEW_USER_PASSWORD + " TEXT not null,"
            + COLUMN_NEW_USER_AGE + " INTEGER"
            + ")";
    db.execSQL(SQL_CREATE_NEWUSER);
    String SQL_CREATE_BALANCE = "CREATE TABLE " + TABLE_BALANCE + "("
            + COLUMN_BALANCE_ID + " INTEGER PRIMARY KEY autoincrement,"
            + COLUMN_BALANCE_DOLLARBALANCE + " INTEGER,"
            + COLUMN_BALANCE_RUBBALANCE + " INTEGER,"
            + COLUMN_BALANCE_NEW_USER_ID + " INTEGER," + "FOREIGN KEY("+COLUMN_BALANCE_NEW_USER_ID+") REFERENCES "
            + TABLE_NEWUSER + "(id) "+ ")" ;
    db.execSQL(SQL_CREATE_BALANCE);
    onCreate(db);
}

@Override
public void onUpgrade(SQLiteDatabase db, int oldVersion, int newVersion) {
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_NEWUSER);
    db.execSQL("DROP TABLE IF EXISTS " + TABLE_BALANCE);
}

} I want to join user and balance tables. How can i do? When i call Create Method, i have exception.

public void CreateUser(View view) {
    etName = (EditText)findViewById(R.id.etName);
    etPassword = (EditText)findViewById(R.id.etPassword);
    etAge = (EditText)findViewById(R.id.etAge);
    String name = String.valueOf(etName.getText());
    String password = String.valueOf(etPassword.getText());
    int age = Integer.parseInt(String.valueOf(etAge.getText()));
    BalanceTable balanceTable = new BalanceTable(0,0);
    NewUserTable newUserTable = new NewUserTable(name,password,age);
    //write to database of user from our edit texts
    DatabaseHandler databaseHandler = new DatabaseHandler(this);
    Log.d("Insert: ", "Inserting ..");
    NewUserDAO dbForUser = new NewUserDAO(this);
    dbForUser.createNewUser(newUserTable);
    BalanceDAO balanceDAO = new BalanceDAO(this);
    balanceDAO.createBalance(balanceTable);
}

From edit text i take data. Help please
