Have you ever seen a message box like below when you build your project with Android Studio 2.0 ?

If not , watch out for this window which will possibly appear when you build your project with studio 2.0 then update it. that will change your Gradle-plugin version to 'com.android.tools.build:gradle:2.0.0' and Gradle-wrapper to distributionUrl=https\://services.gradle.org/distributions/gradle-2.10-all.zip or you can do it yourself .
