I have similar problem and I found some id values of R(main project) and R2(library project) are same. ``` // SettingsActivity.java (in main project) ... @BindView(R.id.nickname) TextView mNicknameView; ... ```...

Oh, I used 8.5.1 before and just found it fixed on 8.6.0 (https://github.com/JakeWharton/butterknife/blob/master/CHANGELOG.md#version-860-2017-05-16) It works well on 8.6.0. Thanks for resolving the issue :)
