First I see that You have Android and Java Tags mentioned So I'm assuming you have to code in JAVA and not Kotlin and If so Please check If you have selected the right Language while creating the Project

Second the Gradle Build is Failing make sure u have all the Gradle Plugins and that your gradle Build Passes as that is the most important part of Android Studio.
