Android Studio - 保持MySQL连接AsyncTask

Question

我有一个名为ConectarAsyncTask的类，我想在MainActivity中连接我的应用程序并保留所有活动，我可以像做辅助线程类吗？

这是我的连接代码：

public class ConectarAsyncTask extends AsyncTask<String, Void, String> {

Connection conn;
String resultadoConexion;

@Override
protected String doInBackground(String... urls) {

    try {
        Class.forName("com.mysql.jdbc.Driver");
        conn = DriverManager.getConnection("jdbc:mysql://1111111/xxxxxxxxxxxxxxxxxxxxxx");
        System.out.println("CONEXION AsyncTask:   "+conn );
        Log.i("Exito", "Conexion a la base de datos realizada con exito");
        resultadoConexion = "Conectado";
    }

    catch (Exception e){
        resultadoConexion = "Error al conectar";
        Log.i("ErrorBBDD", "Error: " + e.getMessage());
        e.printStackTrace();
    }
    return resultadoConexion;
}

public Connection getConn() {
    return conn;
}

public void setConn(Connection conn) {
    this.conn = conn;
}
