Hi,I try use your android-openerp class but i have an issue.
I'm using OpenErp v7
My code:

OpenErpConnect x=OpenErpConnect.login(servername, port_server, db_name,username, pass);
Long[] ids = x.search("res.partner",true, new Object[0]);
System.out.println("IDS="+ids);

servername, port_server, db_name, username and pass are correctly defined.I can connect with my openerp perfectly.
I can execute the methods of read or write(if you know the ids) and works! , but when i try searching the ids happens this:

You add a parameter with value=null: parameters.add(null);

this null is the problem? another parameters in theory aren't null....

Cheers!

using testConnection method i try to test the connection but it returns false.
passing values are correct.

Hi,
I download your last code and try to search, here is the code:

TextView TextDisplay = (TextView) findViewById(R.id.textView1);
OpenErpConnect oc = OpenErpConnect.connect("localhost", 8069, "testdb", "admin", "admin");
Long[] ids = oc.search("res.users", true, new Object[0]);
String result = "";
for(int index = 0; index < ids.length ; index++) {
result += ids[index] + "\n";
}
TextDisplay.setText(result);

But its always error with message: cannot serialize null (same as the first and closed issue).
Also, I think you need to update your README file...

when I call method search like:
Long[] task_detail_img_ids = oc.search("task.detail.img",true, new Object[0]);
it's return xmlexception

How to resolve?

Hi Enric Caumons
I try using your OpenErpConnect.java class and successful in using Create(), Read() methods. But I can't use your Search() method, it always returns null value.

My code is:

oec = OpenErpConnect.connect("192.168.0.106", 8069, "Chill", "admin", "1");
Long[] ids = oec.search("pos.category", new Object[0]);

My params is:
[Chill, 1, 1, pos.category, search, [Ljava.lang.Object;@40f5c5c0, 0, 0, null, null, false]

Thanks

I am struggling with this issue, my search finally works, but only works in the login activity where i created my openerp object, then i pass that object as an extra to other activity, i verify that all the data is alright printing it... seems ok, but when i try to do anything like search, read, testconnection... it fails. I don't know if i am missing something here.

Hi,

I am using your OpenErpConnect Class to login to the server. But I always get an html in the response. Response code is 200, but ends with html.

Below is my code,

OpenErpConnect op = OpenErpConnect.connect("http://192.168.100.29:8069/", 8069, "DevDB", "admin", "openerp");

And in XMLRPClient,

       URL loginUrl = new URL("http://192.168.100.29:8069/");
        XMLRPCClient client = new XMLRPCClient(loginUrl);
        Integer id = (Integer)client.call("login", db, user, pass);
        connection = new OpenErpConnect(server, port, db, user, pass, id);

But in the third line it is failing to login

Can any body tell me where I am going wrong. I am struggling from days for this
