today I just imported a sample app from Android SDK as a module in my project (analytics) and suddenly I got this gradle error when I try to sync it: Plugin is too old
This issue occurs because of the Gradle version changes, since your application uses old version of gradle, you need to update to new version.
This changes needs to be done in build.gradle file, have look at this link http://www.feelzdroid.com/2015/11/android-plugin-too-old-update-recent-version.html. to know how to update the gradle and detailed steps are provided. there.
