As an Android Developer, I believe Gradle Project Sync Failed error is the first error almost every developer get while creating their first project. If you are too one of them, then you are in right place. Here is the full error, “Gradle Project Sync Failed. Basic functionality (e.g. editing, debugging) will not work properly“.

Select Android

From the list of options, select SDK Manager

A new window will open, select SDK Update Site Tab
isable and Re-enable Android Repository option. (Sometime, it may also show you red symbol error.)

Wait for few seconds until it complete the loading process

Once loading complete, click on Apply and OK.

Now, from the area you are able to see this gradle project sync failed error, click on Try Again
