Android Studio 3.0 Flavor Dimension Issue

Android Studio 3.0 Flavor Dimension Issue

Upgraded to Studio Canary build. My previous project of Telegram Messenger is giving following error.

Error:All flavors must now belong to a named flavor dimension. The flavor 'armv7' is not assigned to a flavor dimension. Learn more at https://d.android.com/r/tools/flavorDimensions-missing-error-message.html 

build.gradle(app) edit file:

android {
  ...
  flavorDimensions "default"
  ...
}

 That all, worked my project in android studio 3.0

 Thank you, like and shared fanpage :D
