Android Build a Weather App (2015) Hooking Up the Model to the View Using Butter Knife for Views

I can't get ButterKnife to work.

I am doing everything it says on github and it still doesn't work. I also saw some answers here, but the method of adding it is changed again. The answers I saw are for 8.1.0 and this version is 8.2.8.

Can you post your build.gradle file where you're adding the dependencies and also the activity or fragment code where you are using Butter knife?

In dependencies section of your module-level build.gradle file in addition to

apt 'com.jakewharton:butterknife-compiler:8.2.1'

you also need

compile 'com.jakewharton:butterknife:8.2.1'

i can't get this to work even after trying to follow the instructions on the github. What should the build.gradle file contain? It is disappointing that the appropriate information is not included in the teacher's notes to make this module work correctly.

Can you post your build.gradle files, project and module?

I assume you probably figured it out by now, but I had the same problem, and here's what I did in case someone needs it. I fixed it by putting:

apply plugin: 'com.neenbedankt.android-apt'

on the top of the build.gradle file. And then you need:

    dependencies {
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

in your project build.gradle file, and

dependencies {
    compile 'com.jakewharton:butterknife:8.2.1'
    apt 'com.jakewharton:butterknife-compiler:8.2.1'

in your module build.gradle file.

// Top-level build file where you can add configuration options common to all sub-projects/modules.

buildscript {
    repositories {
        jcenter()
    }
    dependencies {
        classpath 'com.android.tools.build:gradle:2.1.2'
        classpath 'com.neenbedankt.gradle.plugins:android-apt:1.8'

        // NOTE: Do not place your application dependencies here; they belong
        // in the individual module build.gradle files
    }
}

allprojects {
    repositories {

Both files look correct to me. Can you post any error messages and also the code where you're using butter knife?
