Connection.Server := '172.20.1.9:1521:pdksdb;
Connection.Username := 'dblive';
Connection.Password := 'dblive';
Connection.Connect;
finally
Connection.Free;
end;

i'm already make sure that my android connect with the ip server,

1. Make sure that the form contains the TOracleUniProvider component or the OracleUniProvider unit has been added to the USES section.
2. Make sure that you have access to the 172.20.1.9 server from a mobile device, e.g. by executing the following command: ping 172.20.1.9
3. Make sure that pdksdb is a valid SID
Also, let us know whether the error occurs when using our Mobile demo project, which is located in the 'Demos\Mobile' folder (the path is relative to your UniDAC demos installation path).
