Android的连接到Oracle数据库 [英] Android connect to oracle database

问题描述

我是在连接到Oracle数据库的问题。当我启动我的应用程序在模拟器它工作得很好。但是，当我尝试在我的手机上运行它崩溃。我得到以下错误：

Hi i'm having a problem connecting to an oracle database. When I launch my application in emulator it works just fine. But when I try to run it on my phone it crashes. I get the following error:

detailMessageIO异常：网络适配器无法建立连接

detailMessage "Io exception: The Network Adapter could not establish the connection

我的连接code是：

    try {
        Class.forName("oracle.jdbc.driver.OracleDriver");
    } catch (ClassNotFoundException e) {
        e.printStackTrace();
    }
    Connection conn;
    try {
        conn = DriverManager.getConnection("jdbc:oracle:thin:@ip:port/dtabase name","user", "port");

所以，什么可能是一个问题的任何想法吗？在我的手机我有数据连接打开...

So any ideas on what could be a problem? I have the data connection turned on on my phone...

推荐答案

我会猜，要么你有没有要求上网权限您​​的清单，或者你使用的是本地IP和您的设备正在尝试连接通过广域网和不是局域网。

I am going to guess that either you have not requested internet permissions in your manifest or you are using a local IP and your device is trying to connect over WAN and not LAN.
