描述在Debug模式下使用Eclipse时这个代码为Android处理行： con = DriverManager.getConnection（connectionUrl）; 它在Logcat中产生错误，如：

错误

代码这只是本课程的一部分：

import java.sql.*;

public class ConnectURL {

    public static void main() {

        // Create a variable for the connection string.
        String connectionUrl = "jdbc:sqlserver://192.168.1.20:1433;" +
            "databaseName=BD;user=sa;password=pass1;integratedSecurity=true;";

        // Declare the JDBC objects.
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;

            try {
                // Establish the connection.
                Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
                con = DriverManager.getConnection(connectionUrl);
....

请注意我已经在一个文件夹中下载了Microsoft sqlserver jdbc 4.0，在这个项目中有一条带有这条路径的Java构建路径。

java.sql.SQLFeatureNotSupportedException仅在API级别9之后可用。

我猜您的目标是较低的API级别。

找不到类'java.sql.SQLFeatureNotSupportedException'
