Hi guys it has been a long time i updated my ADT. In office it is very difficult to get something updated or installed. Yesterday in my home machine i thought of updating ADT and found superb enhancements. like opening xml layout from java code by Ctrl click. And major change is in Layout editor , In visual layout editor itself you can see your custom view just drag and drop edit xml attributes etc. If you haven’t updated yet do it now its definitely worth.
