Plugin is too old, please update to a more recent version, or set ANDROID_DAILY_OVERRIDE environment variable to

Question

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

Answer 1

This is android's way of telling you to upgrade gradle to the most recent version. You can do two things-

1. Upgrade to the newer version of gradle. You may face new errors after the upgrade (eg, if you are upgrading to 4.1, you will have to adapt to new syntax - "compile" is no longer valid, use "implementation").
2. Update your ANDROID_DAILY_OVERRIDE variable to the value given. Go to Computer -> Properties -> Advanced System Settings -> Environment Variables, and create a new variable or update value of existing ANDROID_DAILY_OVERRIDE. As the name suggests, this value is only valid for one day and next day you will again have to override the variable.
