  • It says offline mode. Are you offline or have enabled offline mode from the Android Studio menus? The issue seems to be that a file cannot be downloaded because of offline mode. – Per Christian Henden Apr 05 '20 at 10:39

It's an internet connection problem. it happens to me from time to time. I usually use a VPN to fix it. and make sure your Gradle setting is not in offline mode.

I solved it! Earlier, after I set up everything on my Android Studio, I switched the Gradle Compiler work mode to --offline in Command-line Options in Settings:

File > Settings > Build, Execution, Deployment > Compiler

This solved the issue. Right after I solved it, I saw a similar solution and concluded that copy pasting the problem from build log may not always work, you should read it attentively, stop and think, and make a conscious search.

Let me know if it solves your problem too, if not we will try to come up with something else.

Toogle the offline mode in the upper right section. This should solve your problem

just go to the gradle section on top right corner, and switch off 'Toggle Offline Mode' (on the top toolbar) and you are good to go
