Answer 1

None of the above worked for me ....

You just need to go to File -> Project Structure or jus press Ctrl+Alt+Shift+S

and then on the top left click Project Make sure that your Android Plugin Version is the same as you Android Studio Version .. This should fix it

additionally

You can also create a new Project and check under Project view initially you'll be in Android .. change the view to ... Project - > gradle (Note .. not .gradle only gradle ) ->wrapper ->gradle-wrapper properties.. open this file and you can see the last line ie ..

distributionUrl=https\://services.gradle.org/distributions/gradle-2.14.1-all.zip

make sure you have the same gradle version in your old files as well
