Having problem using Butter Knife for Building a Weather App

I'm getting a Cannot resolve symbol 'InjectView'. I copy/paste compile 'com.jakewharton:butterknife:7.0.1' into the build.gradle and then sync the gradle. copy/paste the code @InjectView(R.id.timeLabel) TextView mTimeLabel; and that's when I got the error.

Change the line in build.gradle to: compile 'com.jakewharton:butterknife:6.1.0' Then sync project with gradle and try again.

The update to ButterKnife from 6 to 7 changed the names on most of the annotation and functions. Keeping it at version 6 should let you follow along with the course without issue.

There have been a couple of changes in the ButterKnife API recently. either change it in the build.gradle file to a previous version (Version 6). Or use @Bind(R.id.loginText) TextView mLoginText; and @ButterKnife.bind(this);

If you want to continue using ButterKnife 7 you can take a look at the changelog on GitHub to learn the new function names, but if you're following along with the project it's easiest to use version 6, as Seth Kroger suggested.
