Yup, the syntax changed in the version 8.0.

You can check the changelog here: to see al the changes. But from 7.X to 8.X the changelog is:

  • @Bind becomes @BindView and @BindViews (one view and multiple views, respectively).
  • Calls to bind now return an Unbinder instance which can be used to null references. This replaces the unbind API and adds support for being able to clear listeners.
  • New: @BindArray binds String, CharSequence, and int arrays and TypeArray to fields.
  • New: @BindBitmap binds Bitmap instances from resources to fields.
  • @BindDrawable now supports a tint field which accepts a theme attribute.
  • The runtime and compiler are now split into two artifacts.
    compile 'com.jakewharton:butterknife:8.0.0'
    apt 'com.jakewharton:butterknife-compiler:8.0.0'

  • New: apply overloads which accept a single view and arrays of views.

  • ProGuard rules now ship inside of the library and are included automatically.
  • @Optional annotation is back to mark methods as being optional.
