Android Studio 3.0 Flavor Dimension Issue : <p>Upgraded to Studio Canary build. My previous project of Telegram Messenger is giving following error.</p>

<blockquote>
  <p>Error:All flavors must now belong to a named flavor dimension. The flavor 'armv7' is not assigned to a flavor dimension.

<p>What should I do? I have already seen that link but couldn't understand what to do. I have 3 build variants now, release,debug and foss.</p>
