Error "Minimum supported Gradle version is 5.1.1. Current version is 4.4.1" after update android studio

You could just edit YOUR_APPLICATION_FOLDER/gradle/wrapper/gradle-wrapper.properties and change the last line to: distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip Android Studio will download necessary library.

This was my solution.

My_project
  /gradle
  /wrapper
  /gradle-wrapper.properties 

Modify this line with the Gradle 5.1.1

distributionUrl=https\://services.gradle.org/distributions/gradle-5.1.1-all.zip

Finally, I was able to solve this dropping the folders of the oldest version in ~/.gradle/wrapper/dists and leave only the gradle-5.1.1-all
