Can't get android to run

Been trying to set up android for past 2 days.

When I try to run android emulator, I get this error:

[ERROR] :  "Missing Java SDK. Please make sure Java SDK is on your PATH
[ERROR] Application Installer abnormal process termination. Process exit value was 1

?  selected sdk       selected Titanium SDK "vundefined" is not installed
 ?  tools              unsupported version 21.1
 ?  platform tools     unsupported version 16

Here's the LOG file from within titanium. It says there's an issue with updating titanium but when I run check for updates, it's already updated.
