Click on the File menu in the menu bar and Select Invalidate Caches/ Restartmenu.

Close the project and open it again.

There may be various reasons for not building the project:

2. Make sure Java is installed on your system.

3. Install Android Studio as per the instruction given in https://spoken-tutorial.org/media/videos/105/Android-app-using-Kotlin-Installation-Sheet-English.pdf

4.There should not be drop in Internet connection while installing and building the First project. Some of the gradle may not be downloaded completely.

5. It may be due to the long path of the project directory.
