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
Plugin is too old
You can always check the latest gradle plugin version here: https://bintray.com/android/android-tools/com.android.tools.build.gradle
So as of today you should use:
classpath 'com.android.tools.build:gradle:2.2.2'
accordingly.
