Rahat :
My android studion was working fine. But suddenly I can't refactor any of my projects. When I got to the Refactor->rename then the Button Grayed.
I tried re-installing android studio but did not work. Then I updated it to the latest version (From 173.4720617 to Build# AI-173.4819257) but got the same problem.
Even I tried to refactor different projects on another pc but got the same problem.
I don't know how this problem is generated within a night to all of my pc's.
Please help me solving this problem

The button is disabled because you are not changing the package name. Try to change the package name to different text, this will enable the button automatically.
