Question: I haven't used Android Studio in a while, but decided to update everything and create a new project and I get the above error, if I go to Preferences -> Build, Execution, Deployment -> Gradle.

There's no option to 'Work Offline' as suggested here among other places [No cached version of gradle available for offline mode](https://stackoverflow.com/questions/45958541/no-cached-version-of-gradle-available-for-offline-mode)

I've also used the 'Command Shift A' and searched for 'Offline' and I get nothing. Anyway to disable this?

Answer: 
To Enable or Disable Gradle Offline Mode In Android Studio 3.6.1 please see in picture below :

If you want demo video so please have a look on : <https://www.youtube.com/watch?v=50WxM7mu6pg>
The toggle button always says - 'Toggle Offline Mode' and never changes to 'Toggle Online Mode' How will I know whether gradle sync will run in offline mode or online mode?
