To make it work, I have already implemented below suggestions
Few tricks :
1.Clean and Run
File -> Invalidate Caches / Restart... -> Select Invalidate and Restart
2.Turned off Power Save
File -> Power Save Mode
- Delete .idea folder and all .iml and rebuild.
I have uninstalled android studio and re-installed it. None of above worked for me.
I don't understand what to do now? Kindly suggest me resolution of above issue. Thanks..
