Fresh Install of Android Studio, intellij is not showing me errors in the editor.
No lightbulb, no red underlined text. To know where I made errors (even the simplest error like a missing ';' ) I have to compile my Android project .
I'm on x64 all the way & Java JDK 1.7_40.
Thanks !
I found the answer !
Just on top of the right scrollbar there is a small eye icon, wich is called "Code Analysis", it should be green if the file opened in the code editor is without errors.
So what was the problem ? It seems that code analysis is battery hungry and it is desactivated by default when your laptop is on Power Saving Mode.
Uncheck Power Saving Mode, and Voilà !
