Android上的SQLite JDBC驱动程序 [英] SQLite JDBC driver on Android

问题描述

我正尝试使用 xerial sqlite-jdbc 在Android中管理我的数据库，但没有成功.我遇到了java.lang.NoClassDefFoundError: org.sqlite.SQLiteConnection异常.我已将此依赖项'org.xerial:sqlite-jdbc:3.18.0'导入了我的摇篮. 我的代码如下，

I'm trying to use xerial sqlite-jdbc to manage my database in Android with no success.I'm getting an java.lang.NoClassDefFoundError: org.sqlite.SQLiteConnection exception.I've imported this dependency 'org.xerial:sqlite-jdbc:3.18.0' in my gradle. My code is as follows,

 try {

        Class.forName("org.sqlite.JDBC");
        Connection connection = DriverManager.getConnection("jdbc:sqlite:hs.db");

    } catch (ClassNotFoundException eString) {System.err.println("Could not init JDBC driver - driver not found");
    } catch (java.sql.SQLException e) {e.printStackTrace();}

在我的项目中不能使用android.database.sqlite，因此请不要提出答案.

Using android.database.sqlite in my project is not option so please don't suggest that as an answer.

推荐答案

Gradle

 compile 'org.sqldroid:sqldroid:1.0.3'

JAVA

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

public class MainActivity extends AppCompatActivity {

    private Connection connection;

    @Override
    protected void onCreate(Bundle savedInstanceState) {
        super.onCreate(savedInstanceState);
        try {
            DriverManager.registerDriver((Driver) Class.forName("org.sqldroid.SQLDroidDriver").newInstance());
        } catch (Exception e) {
            throw new RuntimeException("Failed to register SQLDroidDriver");
        }
        String jdbcUrl = "jdbc:sqldroid:" + "/data/data/" + getPackageName() + "/my-database.db";
        try {
            this.connection = DriverManager.getConnection(jdbcUrl);
        } catch (SQLException e) {
            throw new RuntimeException(e);
        }
    }

    @Override
    public void onDestroy() {
        if (connection != null) {
            try {
                connection.close();
            } catch (SQLException e) {
                throw new RuntimeException(e);
            }
        }
        super.onDestroy();
    }
}
