AppActivity template is conflicting with My project AppActivity

Hello Devs,

Encountered weird issue.I was integrating facebook sdk a week ago and I got some errors. I deleted the whole repository and cloned cocos project again and created build again. my facebook changes were right there again. Then I realised cocos kept a template copy of AppActivity in following path,

C:\CocosDashboard_1.0.11\resources\.editors\Creator\3.0.1\resources\resources\3d\cocos2d-x-lite\templates\android\template\app\src\com\cocos\game

I think I accidently opened original template in android studio and modified it. I am not sure. Could that be the case? Thanks.
