Error running MyActivity: Gradle project sync failed. Please fix your project and try again

Question

I am new to Android Studio and I have just created a new project with only one Activity with fragments(Android studio created that), and when I ran the MyActivity.java , error occurs:

Error running MyActivity: Gradle project sync failed. Please fix your project and try again.

Nothing more in my event log.

I have no idea why it is, and This link did not helps.

One clue is that Gradle project sync in progress is flowing all the time , just after I restart the Studio.

Answer 1

1. Goto File -> Invalidate caches / Restart
2. Shutdown Android Studio
3. Rename/remove .gradle folder in the user home directory
4. Restart Android Studio (It will download gradle metadata and data)
5. Gradle build succeed
6. Rebuild project
7. Done
