Not able to connect to Oracle DB

While connecting to the DB via SQL Developer, I'm facing following error: Io Exception: The Network Adapter could not establish the connection

I tried to find out the issue and end up seeing that the OracleXETNsListener service is not started. I tried to start it but getting error as : The OracleXETNSListener service on local computer started and then stopped. Some services stop automatically if they are not in use by other services or programs

also tried it through command prompt as follows:

C:\Windows\system32>lsnrctl status

LSNRCTL for 32-bit Windows: Version 11.2.0.2.0 - Production on 16-JUN-2014 15:00

That happened to me when I set the variables ORACLE_HOME & ORACLE_SID, restarted and that error appeared.

Possible Solution: I deleted variables ORACLE_HOME & ORACLE_SID, restarted my computer and everything went ok.
