Question

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:

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

My connectivity code is:

    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");

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

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.
