app grdle error

I am looking for a freelancer to help me with an app gradle error. The specific error message I am encountering is "Gradle sync failed". The app is meant for the Android platform. Currently, I am using a not the latest, but recent version of gradle.

Caused by: org.codehaus.groovy.control.MultipleCompilationErrorsException: startup failed:


Skills and experience required:
- Proficiency in Android app development
- Experience with resolving gradle sync issues
- Familiarity with different versions of gradle and their compatibility with Android apps
