安卓如何调用mysql数据库连接

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.SQLException;

public class MySQLConnector {
    private static final String DB_URL = "jdbc:mysql://<数据库地址>:<端口>/<数据库名>";
    private static final String USER = "<用户名>";
    private static final String PASS = "<密码>";

    public static Connection getConnection() throws SQLException {
        return DriverManager.getConnection(DB_URL, USER, PASS);
    }
}

try {
    Connection conn = MySQLConnector.getConnection();
    // 在这里进行数据库操作
} catch (SQLException e) {
    e.printStackTrace();
    // 处理数据库连接错误
}

try {
    Connection conn = MySQLConnector.getConnection();
    Statement stmt = conn.createStatement();
    String sql = "SELECT * FROM users";
    ResultSet rs = stmt.executeQuery(sql);
    
    // 处理查询结果
    while (rs.next()) {
        String username = rs.getString("username");
        String email = rs.getString("email");
        // 其他操作...
    }
    
    // 关闭连接和结果集
    rs.close();
    stmt.close();
    conn.close();
} catch (SQLException e) {
    e.printStackTrace();
    // 处理数据库操作错误
}
